Sarin is an extremely toxic synthetic organophosphorus compound. A colourless, odourless liquid, it is used as a chemical weapon due to its extreme potency as a nerve agent. Exposure is 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, but do not receive immediate medical treatment, may suffer permanent neurological damage.
The following is a timeline of the Syrian Civil War from May to August 2012. The majority of death tolls reported for each day comes from the Local Coordination Committees, an opposition activist group based in Syria, and the Syrian Observatory for Human Rights, another opposition group based in London.
Human rights violations during the Syrian civil war have been numerous and serious, with United Nations reports stating that the war has been "characterized by a complete lack of adherence to the norms of international law" by the warring parties who have "caused civilians immeasurable suffering". For a relatively small number of these war crimes, prosecution of Syrian civil war criminals has resulted.

There have been very many 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 and the April 2017 sarin attack in Khan Shaykhun. 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. According to a February 2019 study by researchers at the Berlin-based Global Public Policy Institute, chlorine was used in 91.5% of chemical attacks since 2012.
The Ghouta chemical attack occurred in Ghouta, Syria, during the Syrian civil war, in the early hours of 21 August 2013. 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 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.
The Jobar chemical attacks allegedly occurred in Jobar, Damascus, Syria, in April 2013. A reporter and a photographer for the French newspaper Le Monde spent two months in Jobar reporting on the attacks. However, the U.N. mission which investigated the attack could not find "sufficient or credible information" to support the allegation.
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.
Khan al-Assal is a district of Aleppo city in northern Syria. It is administratively a sub-district of Aleppo, which is a part of the Mount Simeon District in the Aleppo Governorate. Khan al-Assal is located 12 kilometers (7.5 mi) west-southwest of the center of Aleppo.
The United Nations Mission to Investigate Allegations of the Use of Chemical Weapons in the Syrian Arab Republic was a fact-finding mission to investigate possible use of chemical weapons in Syria. The mission was established by the U.N. Secretary-general Ban Ki-moon on 21 March 2013 to investigate the 19 March 2013 Khan al-Assal chemical attack that was brought to the Secretary-general's attention by the Syrian Government. On 27 March 2013, the secretary-general appointed Åke Sellström to head the mission. The mission had an OPCW component headed by Scott Cairns and a WHO component headed by Maurizio Barbeschi.
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 Basha'ir al-Nasr Brigade, was an opposition group active in the Syrian Civil War. According to the Russian UN ambassador Vitaly Churkin, the group was affiliated with the Free Syrian Army and was known to produce rocket-propelled unguided missiles in the north of Syria.
The Khan Shaykhun chemical attack took place on 4 April 2017 on the town of Khan Shaykhun in the Idlib Governorate of Syria. The town was reported to have been struck by an airstrike by government forces followed by massive civilian chemical poisoning. The release of a toxic gas, which included sarin, or a similar substance, killed at least 89 people and injured more than 541, according to the opposition Idlib Health Directorate. The attack was the deadliest use of chemical weapons in the Syrian civil war since the Ghouta chemical attack in 2013.
The Jobar sarin attack took place on 24 August 2013 around 11:00 in Jobar, a suburb of the Syrian capital city Damascus.
The Saraqib chemical attack is an alleged attack that supposedly took place in Saraqib in Idlib Governorate in Syria on 29 April 2013.
On 7 April 2018, a chemical warfare attack was carried out in the Syrian city of Douma. 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. The Syrian and Russian governments asserted that a widely circulated video allegedly showing the aftermath of the attack was staged.
