The Khan Shaykhun chemical attack took place on 4 April 2017 on the town of Khan Shaykhun in the Idlib Governorate of Syria. [6] The town was reported to have been struck by an airstrike by government forces followed by massive civilian chemical poisoning. [5] [7] The release of a toxic gas, which included sarin, or a similar substance, [8] killed at least 89 people and injured more than 541, according to the opposition Idlib Health Directorate. [9] [4] [10] The attack was the deadliest use of chemical weapons in the Syrian civil war since the Ghouta chemical attack in 2013. [11]

Contents

The OPCW-UN Joint Investigative Mechanism attributed the responsibility of the attack to the Syrian government. [12] [13] [14] [15] The OPCW-UN JIM described chemicals that it said linked the sarin used to the Syrian government: "The samples from Khan Shaykhun contain the three types of marker chemicals described above: PF6 [HFP], isopropyl phosphates and isopropyl phosphorofluoridates. Their presence is a strong indicator that the sarin disseminated in Khan Shaykhun was produced from DF from the Syrian Arab Republic stockpile." [16] [17]

The governments of the United States, United Kingdom, Turkey, Saudi Arabia, France, and Israel as well as Human Rights Watch attributed the attack to the forces of Syrian President Bashar al-Assad. [18] [19] [20] [21] The Syrian government said the attack was a "fabrication" [22] while the Russian government said that the incident was staged. [23]

On 7 April, the United States launched 59 cruise missiles at Shayrat Air Base, which U.S. intelligence cited as the source of the attack. [24] [25]

Background

Use of chemical weapons in the Syrian Civil War has been confirmed by the local sources in Syria and by the United Nations. Deadly attacks by chemical weapons during the war include the Ghouta attack in the suburbs of Damascus in August 2013 and the Khan al-Assal attack in the suburbs of Aleppo in March 2013. While no party took responsibility for the chemical attacks, a U.N. fact-finding mission and a UNHRC Commission of Inquiry have both investigated the attacks.

The U.N. mission found likely use of the nerve agent sarin in the case of Khan al-Asal (19 March 2013), Saraqib (29 April 2013), Ghouta (21 August 2013), Jobar (24 August 2013) and Ashrafiyat Sahnaya (25 August 2013). The UNHRC commission later confirmed the use of sarin in the Khan al-Asal, Saraqib and Ghouta attacks, but did not mention the Jobar and the Ashrafiyat Sahnaya attacks. The UNHRC commission also found the sarin used in the Khan al-Asal attack bore "the same unique hallmarks" as the sarin used in the Ghouta attack and indicated the perpetrators likely had access to chemicals from the Syrian Army's stockpile. Those attacks prompted the international community to pressure disarmament of the Syrian Armed Forces from chemical weapons, which was executed during 2014. Despite the disarmament process, dozens of incidents with suspected use of chemical weapons followed throughout Syria, the majority being attributed to anti-government fighters, in particular the Al Qaeda affiliate Al Nusra Front. [26]

In August and October 2016, United Nations reports explicitly blamed the Syrian military of Bashar al-Assad for dropping chlorine bombs on the towns of Talmenes on 21 April 2014, Sarmin on 16 March 2015. [27] [28] and Qmenas, also on 16 March 2015. [29] Several other attacks have been alleged, reported and/or investigated. In December 2016, at least 53 people were killed in an alleged chemical weapons attack in ISIL-held villages near Uqairabat that bore similarities to the Ghouta attack, with none of the dead having blast injuries. [30] [31]

The immediate context for the Khan Shaykhun attack was the intensified aerial campaign in March and April 2017 by the government and its Russian ally to gain control of Kafr Zeita, Murek and al-Lataminah, then the three remaining rebel-held towns in the northern Hama Governorate. [32] (See Hama offensive (March–April 2017).) On 30 March 2017, an airstrike hit al-Lataminah, around 15 kilometers (9 miles) from Khan Shaykhun. More than 70 people in the area were then exposed to an unidentified chemical agent and showed symptoms of nausea, agitation, foaming, muscle spasm, and miosis (constriction of the pupil of the eye). Cardiac arrest occurred in two of the victims [33] and an orthopedic doctor died. [34] On 3 April 2017, one day before the Khan Shaykhun attack, a "regime aircraft" allegedly carried out a similar chlorine gas attack on Al-Habit, a nearby village, injuring dozens and killing two children. [35] [36] [37]

The attack took place around 6:30 a.m. local time on 4 April, before most children and parents had left for school or work. [1] [38] [39] Witnesses reported smelling a strange odor about ten minutes after a rocket attack and airstrike, followed by visible symptoms of poisoning. [40] White Helmets volunteers reported four unusually weak explosions. [41] Victims were treated at al-Rahma hospital in Idlib. [39] Medical workers and witnesses said the attack was different than the chlorine gas attacks they had experienced in the past, in which the chlorine gas usually killed a few people in confined spaces and buildings. In contrast, in this attack, many people died outside. Furthermore, the victims exhibited pinpoint pupils, a sign of contact with nerve agents and sarin specifically. [42] [43] [39] Other symptoms reported included coldness in the extremities, decreased heart rate, and low blood pressure, [40] convulsions, foaming at the mouth or vomit, and respiratory paralysis. [39] Some first responders became ill when they came into contact with the victims. [42] [38]

Rescue workers gathered soil and tissue samples and sent them to Western intelligence officials for analysis. [44] On 6 April, the Turkish Ministry of Health, which had conducted tests on people transported to Turkey, said it had identified the chemical used in the attack as sarin, citing lung damage found in victims. [45] On 11 April, Turkish Minister of Health Recep Akdağ stated that isopropyl methylphosphonic acid—a known byproduct of sarin reacting with other compounds—was "identified in the blood and urine tests conducted on samples taken from the victims". [46] Tests by British scientists of samples found at the scene indicated the chemical involved was "sarin or a sarin-like substance". [47] [48]

The Guardian's Kareem Shaheen, the first reporter from western media to visit the town after the attack, photographed the crater where the chemical weapon was reported to have hit an apparently abandoned warehouse and silos near the crater. [49] [50]

Casualties

Medical sources in Idlib in the immediate aftermath of the attack reported more than 58 people, including 11 children, were killed and over 300 were wounded. [5] Test results of samples collected from ten of them indicated they had been exposed to sarin or a sarin-like substance. [51]

By 7:30 a.m. EEST 100 wounded people arrived at a local field hospital. The opposition minister of health, Mohamad Firas al-Jundi, said victims experienced suffocation, fluid in the lungs, foaming at the mouth, unconsciousness, spasm, and paralysis. [42] A few hours after the attack, a nearby clinic treating victims was hit by an airstrike, with reports that Russians bombed the hospital with the victims in an attempt to destroy the evidence. [52] The area's largest hospital was bombed two days prior. [42] According to Dr. Abdel Hay Tennari, who treated 22 victims of the attack, the symptoms of victims corresponded to symptoms of exposure to sarin. Patients who received pralidoxime, an antidote of sarin, reportedly stabilized their medical state in around an hour. [53] Médecins Sans Frontières visited Bab Al Hawa hospital where they determined symptoms consistent with sarin. They also visited other hospitals where victims were taken and reported, "that victims smelled of bleach, suggesting they had been exposed to chlorine." They concluded that the "reports strongly suggest that victims of the attack on Khan Sheikhoun were exposed to at least two different chemical agents." [54]

On 5 April, local doctors and rescue workers at the scene said the number of dead had risen to 74, with 600 injured, [55] and later that day The Daily Telegraph reported 86 deaths, including 30 children, and noted the death toll was rising as so many had died in their homes and only taken to hospitals later. [39] Turkish President Recep Tayyip Erdoğan and French Ambassador to the United Nations François Delattre said over 100 had died. [56] On 7 April, the opposition Idlib Health Directorate said 89 had died, 18 women and 33 children. [57] On 9 May 2017, a report from CNN said the attack killed 92 people in all. [58]

Responsibility

On 6 September 2017, the UN Office of the High Commissioner for Human Rights' Independent International Commission of Inquiry on the Syrian Arab Republic concluded that a Syrian Air Force aircraft was responsible the sarin attack, saying "the Syrian air force used sarin in Khan Sheikhoun, Idlib, killing dozens, the majority of whom were women and children". [2] It dismissed the Syrian and Russian claim that a bomb struck an opposition chemical weapons depot on the outskirts of the northern town as “fabricated”. The report found that a Sukhoi 22 jet, which is only flown by the Syrian airforce, had carried out four airstrikes at 6.45am on 4 April. Three bombs carried conventional explosives, but one, which struck a road, carried the deadly nerve agent, which was carried as far as 600 metres away on a gentle wind. “Weather conditions at 6.45am on 4 April were ideal for delivering a chemical weapon,” the report said. “The wind speed was just over 3km/h, with no rain and practically no cloud cover. Under such conditions, the agent cloud would have drifted slowly downhill following the terrain features at the location.” [59]

The Assad government has repeatedly denied using chemical weapons, but the report said the Syrian government's version of events, that an unknown weapons depot had been hit, was “extremely unlikely”. It said sarin stored in such circumstances would have mostly burned off or been absorbed by rubble, and that there was no evidence of the building being contaminated.

A visit by The Guardian to Khan Sheikhun two days after the attack revealed that the site officials claimed had been hit had been empty for many months, and contained only animal feed and a volleyball net. Witnesses described the frantic aftermath of a series of airstrikes, which overwhelmed the limited capacity of local medics and rescue workers. This finding was confirmed in a report released on 26 October 2017 by the OPCW-UN Joint Investigative Mechanism. [3]

Many governments, such as the United States and some European countries [60] [20] and the Gulf Cooperation Council [61] attributed the attack to the Syrian government. [44] [62] [63] [64] According to investigation by Human Rights Watch, the attack was conducted by Syrian government forces from the air using Soviet-made KhAB-250 aerial bombs designed to deliver sarin. [65] [66] The investigative journalism website Bellingcat suggested Russia may have inadvertently provided evidence of the Syrian government's use of the M4000 chemical bomb. [67] [68] The Syrian government denied any involvement. [44] Immediately following the attacks, Russia said the Syrian Air Force had struck Khan Shaykhun "between 11:30am and 12:30pm local time" on 4 April, but that the target had been "a large terrorist ammunition depot" on its eastern outskirts. "On the territory of the depot, there were workshops which produced chemical warfare munitions", [69] [70] and following the OPCW conclusions, in October 2017, it strongly disputed the conclusion that the Syrian government was responsible.[ citation needed ] The UN Security Council session unanimously declared the need for an investigation of the chemical attack. [71] According to an OPCW report, [72] an investigation into the attack was concluded and released on 29 June 2017, which confirmed the use of sarin gas, or a similar substance. [73] [74] [8] [75]

The United Kingdom’s assessment is that it is almost certain that the Syrian Government was responsible for a sarin attack on Khan Shaykhun on 4 April. (...) There is no evidence to suggest that any party to the conflict in Syria, other than the Syrian Government, has access to a complex nerve agent such as sarin. We note that the FFM’s report refers to testimony from witnesses describing the presence of jets in the area at the time of the attack. Only the Syrian Air Force has the capability to launch a chemical weapons attack from aircraft, and it has already been condemned by this Council for having been found to have used chemical weapons, deployed from aircraft, on at least three occasions in 2014 and 2015.

Claims by the Syrian government, Syrian opposition and Russian government

Syrian opposition claims

According to the Idlib Media Centre, the chemical agent had the characteristics of sarin. The National Coalition for Syrian Revolutionary and Opposition Forces accused the Syrian government and the Syrian Armed Forces of carrying out the attack and called for an immediate investigation by the United Nations Security Council. [5] The opposition groups said the Syrian air force dropped chemical bombs on a civilian population. [26] [77]

Syrian government claims

On the day of the attack, a Syrian government official told Reuters "the government does not and has not used chemical weapons, not in the past and not in the future." [78] Later, the Russian Ministry of Defence reiterated the statement made by the Syrian Armed Forces, and said the attack on the ammunition depot took place between 11:30 and 12:30 EEST. [79]

In a 13 April interview to AFP, President Assad said the attack is "100 per cent fabrication" by the United States "working hand-in-glove with the terrorists", intended to provide a pretext for the airstrike on the Shayrat Airbase. [80] [22]

Russian government claims

The Russian government denied involvement in the chemical attack; Russia's Defence Ministry issued a statement saying the Russian Air Force had "not carried out any strikes near Khan Shaykhun of Idlib province", [81] but said a Syrian aircraft did conduct an airstrike on a warehouse containing ammunition and equipment belonging to rebels near Khan Shaykhun, "yesterday, from 11:30 a.m. to 12:30 p.m". [70] The Russian Foreign Ministry said it was "premature to accuse the Syrian government of using chemical weapons in Idlib", and insist on full and impartial investigation. [74] [82] Shortly after the attack Russian presidential spokesman Dmitry Peskov told reporters the use of chemical weapons is a "dangerous and monstrous crime" and that Russia's support for Assad is not "unconditional". He also said he doubted information was based on "objective materials or evidence", and that only Syrian government can resist "terrorists on the ground." [83] Mikhail Ulyanov, head of the Russian delegation to UNGA First Committee and Director of the Department for Non-Proliferation and Arms Control of the MFA of Russia, stated on the sidelines of the 72nd session of the UN General Assembly that Russia tended to 'more and more to opt for that version' that explained the event as a staged incident, and to doubt that it was the result of an air bomb strike. [84]

Later, President Vladimir Putin said the attack could be a provocation, but that several versions were possible, and the UN should investigate the attack. [85] [86] On 11 April, Putin suggested the chemical attack was a false flag operation intended to discredit the Syrian government. [23]

UK based Bellingcat founder Eliot Higgins observed that Russian claims that a warehouse containing chemical weapons was bombed related to a raid carried out "two to three hours" after the first images of victims appeared. A statement made on the day of the attack by Major General Igor Konashenkov, a spokesperson for the Russian Ministry of Defence was also criticised by Higgins' Bellingcat colleague Dan Kaszeta, a veteran of the US Army Reserve's Chemical Corps, who called it "an infantile argument", and by the anti-Kremlin Russian non-profit Conflict Intelligence Team. [87] [88]

United States reaction

Responsibility assessment

According to the US government, the Syrian government under Assad was behind the chemical attack, [42] and Syrian jets carried out the bombing of a rebel stronghold. [82] U.S. Secretary of State Rex Tillerson was quoted as saying "Either Russia has been complicit or Russia has been simply incompetent". [89] According to Tillerson, the U.S. appealed to Assad to cease the use of chemical weapons, and "[o]ther than that, there is no change to our military posture", [90] with ISIS remaining the primary priority. [91] [92]

President Donald Trump called the attack "reprehensible" and attributed it to the Syrian government, saying the act could not be ignored "by the civilized world" during his meeting with King Abdullah II of Jordan. [93] [94] [95] Trump also blamed the attack on supposed failures of the administration of his predecessor, Barack Obama. [95] [96] U.S. Secretary of State Rex Tillerson said: "Anyone who uses chemical weapons to attack his own people shows a fundamental disregard for human decency and must be held accountable." [95] [97] US representative to the UN Nikki Haley has stated that, though before the chemical attack the US had not considered overthrowing Syrian President Bashar al-Assad from power a top US priority, it is now prominent among US priorities in the region. [91] At the UN Security Council, Haley said "When the United Nations consistently fails in its duty to act collectively, there are times in the life of states that we are compelled to take our own action", [98] by it implying if the UN failed to hold Assad accountable for the use of chemical weapons on civilians, the US will. [99] CIA Director Mike Pompeo confirmed on Thursday 13 April that his agency concluded the Syrian government was responsible for the chemical attack in Khan Shaykhun. “We were good and fast,” Pompeo said. [100] The top Democrat on the house intelligence committee, Rep. Adam Schiff, agreed that the Syrian government was responsible for the attack. [101] [102]

A few members of Congress and former officials expressed skepticism, like Democratic Congresswoman Tulsi Gabbard, [103] Republican Congressman Thomas Massie, [104] and former Republican Congressman Ron Paul. [105]

Missile strike

On the morning of 7 April 2017, 72 hours after the attack, the United States launched 59 cruise missiles on Shayrat Airbase, a Syrian airfield near Shayrat, believed to be the base for the aircraft that carried out the chemical attack. [24] In contrast to the coalition's accidental air raid on Deir ez-Zor in 2016, this was both a unilateral action and the first intentional strike against the Syrian government. [106] [107]

Sanctions

On 24 April 2017, the United States Department of the Treasury imposed sanctions on 271 employees of the Syrian Scientific Studies and Research Center for their alleged role in producing chemical weapons. [108] [109]

International reactions

Supranational and non-governmental organizations

Secretary-General António Guterres said he was "deeply disturbed" by reports of the Idlib chemical attack, noting that the use of chemical weapons is banned under international law. [110] Federica Mogherini, the European Union's diplomatic chief, called the attack "awful" and said Bashar al-Assad's government bore "primary responsibility" for it. [111]

The Organisation for the Prohibition of Chemical Weapons (OPCW) expressed "serious concern" and said its Fact-Finding Mission in Syria was "gathering and analysing information from all available sources." [112] The following day, the Technical Secretariat of the OPCW, referring to the media reports, requested all member states of the Chemical Weapons Convention to share available information on what it described preliminary as "allegations of use of chemical weapons in the Khan Shaykhun area of Idlib province in the Syrian Arab Republic." [113] Amnesty International said the evidence points to an "air-launched chemical attack", [114] while the World Health Organization said victims carried the signs of exposure to nerve agents. [114] On 26 October, an investigative panel created by the UN Security Council said it was "confident" that Assad's air force was behind the chemical attack. Further, that the attack was possible because it drew from old Syrian stockpiles that Assad had vowed to destroy in 2013, indicating that Damascus has systematically cheated international inspectors for the past four years. [84] [12] [14] [13]

UN Security Council countries

France called for an emergency meeting of the United Nations Security Council after the attack. [115] [116] France, Britain, and the United States (who are among the permanent members of the Security Council), circulated a draft to the council's 15 members condemning the attack in Syria and demanding a full investigation into it. The emergency closed-door meeting was set on 5 April in New York. [117] [118] United States Ambassador to the United Nations Nikki Haley, serving as president of the Security Council for the month, announced there would not be a vote on a draft resolution to respond to the chemical weapons attack, but instead of one resolution by the U.S. and a second resolution by Russia, there was a third resolution unexpectedly submitted by Sweden and nine other non-permanent members. When the council concluded its meeting without conclusion on the morning of 6 April, the U.S. launched a missile strike. [119] On 12 April, the proposed draft resolution was vetoed by Russia as it attributed blame to the Syrian government before any investigation had been undertaken.[ citation needed ] This was the eighth time that Russia vetoed a Security Council resolution on Syria. [120] [121] Instead, on 20 April, Russia and Iran formally proposed to start an OPCW investigation (which was rejected as an investigation is already in progress) [122] and then on 26 April blocked UN resolution calling Syria to disclose information for the first OPCW investigation [123] at the same accusing UN of "blocking independent international investigation" earlier proposed by Russia and Iran. [124]

On 26 April 2017, French Foreign Minister Jean-Marc Ayrault said France had concluded that the Syrian government was "unquestionably" the perpetrator of the attack. [125] [126] He added that the same mixture of sarin and hexamine had been used in the 2013 Saraqib chemical attack. [125]

United Kingdom government defense minister, Michael Fallon said he believed the Syrian air force responsible for the attack. Opposition leader Jeremy Corbyn said "There should now be an immediate ceasefire and a UN-led investigation rapidly into what is a horrific and totally illegal action by somebody using chemical weapons against innocent people." [127]

The Egyptian Foreign Ministry released a statement saying the "painful and unacceptable" images of the massacre reaffirm the necessity of reaching a political solution to end the crisis in Syria, in light of the international community decisions and Security Council Resolution 2254, as well as the Geneva Conventions. [128]

Other countries

Iranian President Hassan Rouhani called for an "impartial international fact-finding body" to be set up to investigate the attack. [129] Foreign minister Mohammad Javad Zarif described the incident as "very painful" and condemned it, but also criticized US for attacking the Syrian airbase "without doing investigation". [130] Iranian Foreign ministry spokesman Bahram Ghassemi condemned "all use of chemical weapons," but suggested the blame for the attack lay with "terrorist groups" rather than the Syrian government. [131]

Canadian Prime Minister Justin Trudeau said: "There are continuing questions ... about who is responsible for these horrible attacks against civilians, and that's why I'm impressing on the UN Security Council to pass a strong resolution that allows the international community to determine first of all who was responsible for these attacks and how we will move forward." [132] Israeli Prime Minister Benjamin Netanyahu called on the international community "to fulfill its obligation from 2013 to fully and finally remove these horrible weapons from Syria". [133] Other countries who condemned the chemical attack include the Czech Republic, [134] Italy, [135] Pakistan, [136] Saudi Arabia, [137] Switzerland, [138] United Kingdom, [117] and the Vatican City. [139]

The Iraqi government condemned the chemical attack and called for an "initiative aimed at punishing those responsible". The next day, Iraqi cleric Muqtada al-Sadr also condemned the attacks and called for President Assad to step down. [140] Australian Prime Minister Malcolm Turnbull said if al-Assad was found to be behind the attack, as the United States believe, it represented "a shocking war crime." [141] Other countries who accused Assad for responsibility include Qatar [142] and Turkey. [143] [144]

Other views

Former head of the International Atomic Energy Agency (IAEA), Hans Blix, described the US retaliation as "measured" and specific, [145] but later criticized the rapid American military response. [146] He initially raised concern that the responsibility of the Syrian government was not yet proven, [145] but stated on 11 April 2017, "On balance it seems probable that the attack with gas was undertaken by the Syrian government air force," adding that "the factual circumstances known so far do not point to the rebels as arranging the gas action". [146]

Other people who have expressed skepticism of the Syrian government being responsible for the attack include former UN weapons inspector   Scott Ritter, [26] [147]  [ non-primary source needed ] US based weapons expert and MIT professor emeritus Theodore Postol, [148] [149] former UK ambassador to Syria  and director of the British Syrian Society Peter Ford, [150] [151] investigative Israeli journalist Uri Avneri, [152] [ non-primary source needed ] and investigative journalist Seymour Hersh. [149] [153] [154] The OPCW-UN JIM report found no merit in any of these views and concluded that the sarin used in the attack bore the Syrian government's signature; "the Leadership Panel is confident that the Syrian Arab Republic is responsible for the release of sarin at Khan Shaykhun on 4 April 2017". [84] [155]

In 2019, the Princeton University-linked journal Science & Global Security , on whose editorial board Ted Postol sat, [156] intended to publish a paper titled "Computational Forensic Analysis for the Chemical Weapons Attack at Khan Sheikhoun on 4 April 2017" written by Goong Chen, Cong Gu, Postol, Alexey Sergeev, Sanyang Liu, Pengfei Yao and Marlan O. Scully. The article questioned the findings of the UN/OPCW investigation which concluded that the Syrian government had used sarin. [157] The report's arguments were rebutted in a Bellingcat article that detailed inconsistencies and anomalies in the report's analysis. [158] In response to the Bellingcat article, the editors of Science & Global Security said “Regrettably, the Bellingcat group blog post contains a number of incorrect statements about the contents and conclusions of the paper to be published. Some of the statements appear to refer to an earlier manuscript and do not take account of all the changes made during the peer review and editorial process managed by this journal”. [157] The journal later decided not to publish the paper. [157] [159]

Sarin is an extremely toxic organophosphorus compound. A colourless, odourless liquid, it is used as a chemical weapon due to its extreme potency as a nerve agent. Exposure can be lethal even at very low concentrations, where death can occur within one to ten minutes after direct inhalation of a lethal dose, due to suffocation from respiratory paralysis, unless antidotes are quickly administered. People who absorb a non-lethal dose and do not receive immediate medical treatment may suffer permanent neurological damage.

There have been numerous reports of chemical weapons attacks in the Syrian Civil War, beginning in 2012, and corroborated by national governments, the United Nations (UN), the Organisation for the Prohibition of Chemical Weapons (OPCW), Human Rights Watch (HRW), and media organizations. The attacks occurred in different areas of Syria, including Khan al-Assal, Jobar, Saraqib, Ashrafiyat Sahnaya, Kafr Zita, Talmenes, Sarmin and Douma. The deadliest attacks were the August 2013 sarin attack in Ghouta, the April 2017 sarin attack in Khan Shaykhun and April 2018 Douma chemical attacks. The most common agent used is chlorine, with sarin and sulphur mustard also reported. Almost half of the attacks between 2014 and 2018 were delivered via aircraft and less than a quarter were delivered from the ground, with the remaining attacks having an undetermined method of delivery. Since the start of uprisings across Syria in 2011, Syrian Arab Armed Forces and pro-Assad paramilitary forces have been implicated in more than 300 chemical attacks in Syria.

The Ghouta chemical attack was a chemical attack carried out by the forces of Syrian President Bashar al-Assad, in the early hours of 21 August 2013 in Ghouta, Syria during the Syrian civil war. Two opposition-controlled areas in the suburbs around Damascus were struck by rockets containing the chemical agent sarin. Estimates of the death toll range from at least 281 people to 1,729. The attack was the deadliest use of chemical weapons since the Iran–Iraq War.

The Independent International Commission of Inquiry on the Syrian Arab Republic was set up by the United Nations Human Rights Council (UNHRC) on 22 August 2011 to investigate human rights violations during the Syrian Civil War to establish the facts and circumstances that may amount to violations and crimes and, where possible, to identify those responsible to be held accountable with a future prosecution of Syrian civil war criminals. The Commission posts regular updates via its official Twitter page.

The Khan al-Assal chemical attack was a chemical attack in Khan al-Assal, Aleppo, Syria on 19 March 2013, which according to the Syrian Observatory for Human Rights resulted in at least 26 fatalities including 16 government soldiers and 10 civilians, and more than 86 injuries. Immediately after the incident, the Syrian government and opposition accused each other of carrying out the attack, but neither side presented clear documentation. The Syrian government asked the United Nations to investigate the incident, but disputes over the scope of that investigation led to lengthy delays. In the interim, the Syrian government invited Russia to send specialists to investigate the incident. Samples taken at the site led them to conclude that the attack involved the use of sarin, which matched the assessment made by the United States. Russia held the opposition responsible for the attack, while the US held the government responsible. UN investigators finally arrived on the ground in Syria in August, but their arrival coincided with the much larger-scale 2013 Ghouta attacks which took place on 21 August, pushing the Khan al-Assal investigation "onto the backburner" according to a UN spokesman. The UN report, which was completed on 12 December, found "likely use of chemical weapons in Khan al-Assal" and assessed that organophosphate poisoning was the cause of the "mass intoxication".

Syria's chemical weapons program began in the 1970s with weapons and training from Egypt and the Soviet Union, with production of chemical weapons in Syria beginning in the mid-1980s. For some time, Syria was believed to have the world's third-largest stockpile of chemical weapons, after the United States and Russia. Prior to September 2013 Syria had not publicly admitted to possessing chemical weapons, although Western intelligence services believed it to hold one of the world's largest stockpiles. In September 2013, French intelligence put the Syrian stockpile at 1,000 tonnes, including Yperite, VX and "several hundred tonnes of sarin". At the time, Syria was one of a handful of states which had not ratified the Chemical Weapons Convention. In September 2013, Syria joined the CWC, and agreed to the destruction of its weapons, to be supervised by the Organisation for the Prohibition of Chemical Weapons (OPCW), as required by the convention. A joint OPCW-United Nations mission was established to oversee the destruction process. Syria joined OPCW after international condemnation of the August 2013 Ghouta chemical attack, for which Western states held the Syrian government responsible and agreed to the prompt destruction of its chemical weapons, resulting in U.S. Secretary of State John Kerry declaring on 20 July 2014: "we struck a deal where we got 100 percent of the chemical weapons out." The destruction of Syria's chemical weapons that the Assad government had declared was completed by August 2014, yet further disclosures, incomplete documentation, and allegations of withholding part of Syria's chemical weapons stockpile since mean that serious concerns regarding chemical weapons and related sites in Syria remain. On 5 April 2017, the government of Syria allegedly unleashed a chemical attack that killed 70 civilians. A suspected chemical attack on Douma on 9 April 2018 that killed at least 49 civilians has been blamed on the Syrian Government.

<span class="mw-page-title-main">Destruction of Syria's chemical weapons</span> Part of the Syrian peace process

The destruction of Syria's chemical weapons began on 14 September 2013 after Syria entered into several international agreements which called for the elimination of Syria's chemical weapon stockpiles and set a destruction deadline of 30 June 2014. Also on 14 September 2013, Syria acceded to the Chemical Weapons Convention (CWC) and agreed to its provisional application pending its entry into force on 14 October. Having acceded to the CWC, the Organisation for the Prohibition of Chemical Weapons (OPCW) Executive Council on 27 September approved a detailed implementation plan that required Syria to assume responsibility for and follow a timeline for the destruction of Syrian chemical weapons and Syrian chemical weapon production facilities. Following the signing of the Framework Agreement on 14 September 2013 and after the OPCW implementation plan, on 27 September the United Nations Security Council unanimously adopted Resolution 2118 which bound Syria to the timetable set out in the OPCW implementation plan. The joint OPCW-UN mission was established to oversee the implementation of the destruction program.

The Report on the Alleged Use of Chemical Weapons in the Ghouta Area of Damascus on 21 August 2013 was a 2013 report produced by a team appointed by United Nations Secretary-General (UNSG) Ban Ki-moon to investigate alleged chemical weapon attacks during the Syrian civil war. The report published on 16 September 2013 focused on the 21 August 2013 Ghouta chemical attack, which took place whilst the Mission was in Damascus to investigate prior alleged incidents, including the Khan al-Assal chemical attack in March 2013.

The 2014 Kafr Zita chemical attack occurred on 11 April 2014, in the rebel-held northern Syrian town of Kafr Zita during the Syrian Civil War. The attack reportedly wounded around 100 people and killed three. Syria's state television, SANA blamed the attack on the Islamist Al-Nusra Front using "toxic chlorine", while the opposition blamed barrel bombs dropped by government forces.

The OPCW Fact-Finding Mission in Syria is a mission of the Organisation for the Prohibition of Chemical Weapons (OPCW) to investigate some possible cases of the use of toxic chemicals in Syria during the civil war, including chlorine. The 21 August 2013 Ghouta chemical attack used sarin. The OPCW-Director General Ahmet Üzümcü announced the creation of the mission on 29 April 2014. This initial mission was headed by Malik Ellahi. The Syrian Government agreed to the Mission.

The United Nations Security Council adopted United Nations Security Council resolution 2235 (2015) on 7 August 2015, in response to use of chemical weapons in the Syrian Civil War. The resolution condemned "any use of any toxic chemical, such as chlorine, as a weapon in the Syrian Arab Republic" and expressed determination to identify and hold accountable those responsible for such acts. The resolution established a Joint Investigative Mechanism (JIM), a partnership between the United Nations (UN) and the Organisation for the Prohibition of Chemical Weapons (OPCW). The Security Council renewed the JIM's mandate in resolution 2319 (2016) on 17 November 2016, for a further period of one year.

During the Syrian Civil War, Russian and Syrian government forces have conducted a campaign that has focused on the destruction of hospitals and medical facilities within areas not under the control of the Syrian government. Russian and Syrian officials have repeatedly denied deliberately targeting medical facilities.

The Saraqib chemical attack is an alleged attack that was reported to take place in Saraqib in Idlib Governorate in Syria on 29 April 2013. A further attack occurred in February 2018, during which, according to the United Nations Organisation for the Prohibition of Chemical Weapons (OPCW) Investigation and Identification Team (IIT), “at least one cylinder” of chlorine gas was dropped, spreading “over a large area” and affecting at least 12 Syrians on the ground. The IIT attributed the attack to Syrian government military, specifically the Syrian Arab Army's Tiger Forces.

On 7 April 2018, a chemical warfare attack was launched by the forces of the government of Bashar al-Assad in the city of Douma, Syria. Medics and witnesses reported that it caused the deaths of between 40 and 50 people and injuries to possibly well over 100. The attack was attributed to the Syrian Army by rebel forces in Douma, and by the United States, British, and French governments. A two-year long investigation by the Organisation for the Prohibition of Chemical Weapons (OPCW) Investigation and Identification Team (IIT) concluded in January 2023 that the Syrian Air Force perpetrated the chemical attacks during its military campaign in Douma. On 14 April 2018, the United States, France and the United Kingdom carried out a series of military strikes against multiple government sites in Syria.

<span class="mw-page-title-main">Northwestern Syria offensive (April–August 2019)</span> Syrian government military operation against rebels

The 2019 northwestern Syria offensive, codenamed "Dawn of Idlib", was a military operation launched on 30 April 2019 by the Syrian Armed Forces and its allies against rebel groups in northwestern Syria during the Syrian civil war in a region known as "Greater Idlib", consisting of northwest Hama, southern Idlib and northeastern Latakia provinces. The government's main objectives were to open the M5 highway and to expel non-compliant militant groups, particularly the internationally proscribed al-Qaeda-linked group known as Hayat Tahrir al-Sham (HTS), from the 15–20 km demilitarized zone demarcated by Turkey and the Russian Federation at Sochi in 2018. The offensive was seen by both parties as crucial to the outcome of the war.
