Tens of thousands of civilians killed by IS (per Iraqi Body Count and SOHR)[93][94] Between 8,214 and 13,125 civilians killed by Coalition airstrikes in Syria and Iraq (per Airwars)[95] 1,335 civilians killed by Coalition Operations (per AirWars)[95]
Over 970,000 civilians in Iraq and Syria displaced, or fled to Turkey and other countries[96][97][98][99]
According to the Pentagon, by March 2019, the day of the territorial defeat in Syria of IS, CJTF-OIR and its partner forces had liberated nearly 110,000 square kilometers (42,471 square miles) of land and 7.7 million people from IS, the vast majority of the self-proclaimed caliphate's territory and subjects.[103] By October 2017, around the time of IS's territorial defeat in Iraq, CJTF-OIR claimed that around 80,000 IS militants had been killed by it and its allies (excluding those targeted by Russian and Syrian Air Force strikes). By the end of August 2019, it had conducted 34,573 strikes.[85][104][105] Tens of thousands more were killed by partner forces on the ground (the SDF alone claimed to have killed 25,336 IS fighters by the end of 2017).[106]
Unlike their coalition partners, and unlike previous combat operations, no name was initially given to the conflict against IS by the U.S. government.[107] The decision to keep the conflict nameless drew considerable media criticism.[108][109][110][111][112]
The U.S. decided in October 2014 to name its military efforts against IS as "Operation Inherent Resolve"; the U.S. Central Command (CENTCOM) news release announcing the name noted that:
According to CENTCOM officials, the name INHERENT RESOLVE is intended to reflect the unwavering resolve and deep commitment of the U.S. and partner nations in the region and around the globe to eliminate the terrorist group ISIL and the threat they pose to Iraq, the region and the wider international community. It also symbolizes the willingness and dedication of coalition members to work closely with our friends in the region and apply all available dimensions of national power necessary—diplomatic, informational, military, economic—to degrade and ultimately destroy ISIL.[113]
By 4 December 2014, three U.S. service members had died from accidents or non-combat injuries.[116]
2015
In November of 2015, Commodore Captain Augustus Bennett commanding the USS Kearsarge (LHD-3) Amphibious Ready Group entered the 5th Fleet AOR in conjunction with the 26th Marine Expeditionary Unit under the command of Colonel Robert Fulford, consisting of the, USS Arlington (LPD-24) and USS Oak Hill (LSD-51)[117] to commence airstrikes on IS. Prior to this, the ARG rendezvoused with the Turkish Navy for Egemen 2015.[118] They concluded their OIR mission on March 10 with a total of 130 sorties and 60 strikes.[119]
From May, North American Rockwell OV-10 Broncos joined the operation, flying more than 120 combat sorties over 82 days. It is speculated they provided close air support for special forces missions. The experiment ended satisfactorily, but a US Air Force spokesman stated it remains unlikely they will invest in reactivating the OV-10 on a regular basis because of the overhead cost of operating an additional aircraft type.[123][124]
By 9 March 2016, nearly 11,000 airstrikes had been launched on IS (and occasionally Al-Nusra), killing over 27,000 fighters[125] and striking over 22,000 targets, including 139 tanks, 371 Humvees, and 1,216 pieces of oil infrastructure. Approximately 80% of these airstrikes have been conducted by American forces, with the remaining 20% being launched by other members of the coalition, such as the United Kingdom and Australia. 7,268 strikes hit targets in Iraq, while 3,602 hit targets in Syria.[86] On 12 June 2016, it was reported that 120 IS leaders, commanders, propagandists, recruiters and other high-value individuals were killed so far this year.[126]
Until March 2016, U.S. military members were ineligible for Campaign Medals and other service decorations due to the continuing ambiguous nature of the continuing U.S. involvement in Iraq.[127] However, on 30 March 2016, U.S. Secretary of Defense Ash Carter announced the creation of a new medal, named "Inherent Resolve Campaign Medal".[128]
On 3 June 2016, aircraft flying from the USSHarry S. Truman in the Mediterranean Sea began airstrikes on IS.[129] On 16 June 2016, AV-8B II+ Harriers of the 13th MEU flying from the USSBoxer in the Persian Gulf also began airstrikes on IS, marking the first time the U.S. Navy used ship-based aircraft from both the Mediterranean and the Persian Gulf at the same time during Operation Inherent Resolve.[130]
By 27 July 2016, U.S. and coalition partners had conducted more than 14,000 airstrikes in Iraq and Syria: Nearly 11,000 of those strikes were from U.S. aircraft and the majority of the strikes (more than 9,000) were in Iraq. Of the 26,374 targets hit, nearly 8,000 were against IS fighting positions, while approximately 6,500 hit buildings; IS staging areas and oil infrastructure were each hit around 1,600 times.[131] On 15 December 2016, the U.K. Defense Secretary Michael Fallon said that "more than 25,000 Daesh fighters have now been killed," a number that was half of the United States' estimate.[132] When asked about this discrepancy, the UK's Ministry of Defense said that it stood by his estimate.[132]
Since the first U.S. airstrikes on IS targets in Iraq on 8 August 2014, over two years, the U.S. military has spent over $8.4 billion fighting IS.[133]
BBC News reported in 2017 that according to the American think tank Council on Foreign Relations, in 2016 alone, the U.S. dropped 12,192 bombs in Syria and 12,095 in Iraq.[134]
Operation Odyssey Lightning
From August to December 2016, the U.S. conducted another similar operation in Libya, code-named Operation Odyssey Lightning, during the battle to capture Sirte, which was the local capital of IS's Libyan branch.[135][136] In September 2017, the US Africa Command announced that 495 precision airstrikes were carried out and 800 to 900 IS fighters were killed during the operation in Sirte between 1 August and 19 December 2016.[137] On 18 January 2017, US B-2 bombers bombed two IS camps to the south of Sirte, killing ninety IS militants.
According to the Syrian Observatory for Human Rights, Coalition airstrikes have killed 7,043 people across Syria, of which: 5,768 dead were IS fighters, 304 Al-Nusra Front militants and other rebels, 90 government soldiers and 881 civilians. The air strikes occurred in the period between 22 September 2014 and 23 January 2017.[138]
In March 2017, various media outlets reported that conventional forces from the 11th MEU, as well as special operations forces in the form of the 75th Ranger Regiment[139] deployed to Syria to support U.S.-backed forces in liberating Raqqa from IS occupation. The deployment marked an escalation in the U.S. intervention in Syria.[140]
By 28 February, the Coalition had conducted 3,271 sorties in 2017, 2,129 of which resulted in at least one weapon released. In total, the coalition released 7,040 weapons in Iraq and Syria in this same time period in an effort to destroy IS.[141]
As of 9 August 2017, coalition aircraft flew a total of 167,912 sorties, and conducted 13,331 strikes in Iraq and 11,235 strikes in Syria, for a total of 24,566 strikes.[142]
In February 2018, the 2nd Brigade Combat Team, 101st Airborne Division was awarded a campaign streamer following its deployment to Iraq. In May 2016, the brigade deployed to advise and assist, train and equip Iraqi security forces to fight the Islamic State of Iraq. The 2nd Brigade also conducted precision surface-to-surface fires and supported a multitude of intelligence and logistical operations for coalition and Iraqi forces. They also provided base security throughout more than twelve areas of operations. The Brigade also aided in the clearance of IS from Fallujah, the near elimination of suicide attacks in Baghdad, and the introduction of improved tactics that liberated more than 100 towns and villages. The 2nd Brigade, 101st Airborne Division also played a significant role in the liberation of Mosul.[143]
In early 2019, the US-led coalition focused on the final assault on ISIS in the Euphrates pocket, including the Battle of Baghuz Fawqani in the first quarter of the year. Civilian human shields held by ISIS were among the victims, including in one reported massacre on 19 March in which up to 300 civilians, including 45 children, were alleged to have been killed by Coalition forces.[144]
From 8 August 2014, to 29 August 2019, coalition aircraft conducted a total of 34,573 strikes.[105]
On 31 December 2019, the CJTF-OIR reported its forces were "closely monitoring the current situation of the protests at the US Embassy in Baghdad", adding that they were "taking the appropriate force protection measures to ensure [US Embassy personnel] safety".[146]
CJTF-OIR paused all training and anti-ISIS operations on 5 January 2020, to focus on protecting Iraqi bases hosting Coalition troops in the wake of several rocket attacks.[147] This action was also linked to the anticipated response against Coalition forces in the wake of the killing of Iranian General Qasem Soleimani.[148] In March 2020, the U.S. military started to withdraw from various bases in Iraq.[149]

On 31 March 2021, Carrier Air Wing Three launched naval flight operations in support of Operation Inherent Resolve. The USS Dwight D. Eisenhower and its carrier strike group were expected to lead Task Force 50, which oversees Operation Inherent Resolve's naval strike operations.[150]
On 3 April, U.S. forces killed senior Islamic State leader Khalid 'Aydd Ahmad al-Jabouri, who was allegedly planning attacks in Europe during Easter, in an overnight drone strike on the outskirts of rebel-held town of Killi, Idlib in northwest Syria.[151]
On 9 July, US Central Command announced that a U.S. MQ-9 drone which had been harassed by Russian aircraft for almost two hours had on 7 July killed an ISIS leader called Usamah al-Muhajir,[152] who had been riding his motorcycle on the road linking al-Bab with Bizaah.[153]
On 24 August, the U.S. Military stated that Major General Joel ‘JB’ Vowell had assumed command of anti-ISIS operation also known as Operation Inherent Resolve, from Major General Matthew McFarlane.[154]
On 20 November, the United States Central Command has announced that, in the months of September and October, it has conducted, along with coalition and other partners, a total of 79 operations in Iraq and Syria resulting in 13 ISIS operatives killed and 78 detained.[155][156]
On 30 August, United States Central Command reported that "[U.S.] forces and Iraqi Security Forces conducted a partnered raid in Western Iraq in the early hours of Aug. 29, resulting in the death of 15 ISIS operatives."[157] It was later confirmed that 7 U.S. troopers were injured during the operation.[158]
U.S. and coalition forces are training Iraqi forces at four sites: in al-Asad in Anbar province, Erbil in the north, and Taji and Besmayah in the Baghdad area.
Meanwhile, The New York Times reported that the Pentagon was planning to "leave 150 Special Operations forces at a base called al-Tanf".[180] In addition, 200 U.S. soldiers would remain in eastern Syria near the oil fields, to prevent the Islamic State, Syrian government and Russian forces from advancing in the region.[181] However, at least 600–900 U.S. Troops are expected to stay in Syria,[182] in Al-Hasakah and Deir ez-Zor Governorates.[183] In July 2020, the U.S. military built a new base including an airport, located between Um Kahif village and Tal Alu silos near Al-Yaarubiyah.[184]
According to Airwars, in 2014 there were 63 incidents involving the US-led coalition in Iraq and Syria in which there were civilian casualties, causing at least 160 civilian deaths. In 2015, there were 268 incidents and 708 deaths. In 2016, there were 483 incidents and 1,372 deaths. Civilian casualties peaked in 2017, with 1,841 incidents and at least 4,677 civilian deaths.[144]
According to Airwars, 1,472 civilians were killed by the U.S. air campaign in Iraq and Syria in March 2017 alone.[185] On 17 March, a U.S.-led coalition airstrike in Mosul killed more than 200 civilians.[186] Data compiled by Airwars shows that 229 strikes in Iraq and 878 strikes in Syria were carried out by Coalition forces in June 2017, killing an alleged total of 1,483 people. The reporting of 875 of those total alleged deaths is contested. In July 2017, Airwars recorded reports of an alleged 1,342 people were killed in Iraq and Syria by Coalition airstrikes. Of the allegations 812 were contested, and two were disproved.[187]
Casualty figures fell after the 2017 peak. According to Airwars, 2018 saw 192 incidents and 846 deaths; 2019 saw 72 incidents and 467 deaths.[144] In 2019, the casualties were concentrated in the first quarter during the Battle of Baghuz Fawqani including an alleged massacre of civilian human shields on 19 March.[144]
By 2020, Airwars had recorded a five-year total of 14,771 US-led Coalition strikes in Iraq and 19,829 in Syria and investigated 2,921 alleged civilian casualty incidents, estimating 8,259–13,135 civilian deaths, of whom around 2,000 were children, although the Coalition itself estimated just 1,377 or 1,417 civilian deaths.[188][189][190]
The New York Times reported that efforts to minimize and count civilian deaths fell far short of the approach promised by the US military for its use of airstrikes in the war against IS. The newspaper reported that airstrikes against IS, as well as in the war in Afghanistan, was marked by "flawed intelligence, poor targeting and thousands of civilian deaths." It also reported that efforts to minimize civilian casualties diminished after President Trump assumed office in 2017, stating "... the authority to approve strikes was pushed further down the chain of command, even as an overwhelming majority of strikes were carried out in the heat of war, and not planned far in advance." Finally, the paper reported that the US military systematically under-reported casualties, providing a total death count of 1,417, when the actual count was significantly higher. The report states that the military made little effort to accurately determine civilian casualties after the airstrikes. The military was also reluctant to divulge information about the casualties, in spite of promises of transparency, and news media were required to make numerous requests under the Freedom of Information Act, and had to repeatedly sue the US military to produce data.[191][192][193]
Talon Anvil
During the years 2014 to 2019, an Air Force special operations group named Talon Anvil killed a significant number of non-combatant civilians, and often failed to follow US military protocols designed to minimize civilian casualties.[194] In one particular strike, the March 2019 Baghuz airstrike, approximately 50 women and children were killed, and the Air Force subsequently covered the deaths up.[195] The Talon Anvil group operated under the auspices of Task Force 9, which was the US military unit responsible for ground operations in the war against IS in Syria. The group consisted of about twenty plainclothes military personnel that operated out of anonymous office buildings in Iraq and Syria.[194] In December 2021, the US Secretary of Defense ordered an investigation into the civilian deaths caused by Talon Anvil's bombing strikes.[194]
The War in Iraq (2013–2017) was an armed conflict between Iraq and its allies and the Islamic State. Following December 2013, the insurgency escalated into full-scale guerrilla warfare following clashes in the cities of Ramadi and Fallujah in parts of western Iraq, and culminated in the Islamic State offensive into Iraq in June 2014, which lead to the capture of the cities of Mosul, Tikrit and other cities in western and northern Iraq by the Islamic State. Between 4–9 June 2014, the city of Mosul was attacked and later fell; following this, Prime Minister Nuri al-Maliki called for a national state of emergency on 10 June. However, despite the security crisis, Iraq's parliament did not allow Maliki to declare a state of emergency; many legislators boycotted the session because they opposed expanding the prime minister's powers. Ali Ghaidan, a former military commander in Mosul, accused al-Maliki of being the one who issued the order to withdraw from the city of Mosul. At its height, ISIL held 56,000 square kilometers of Iraqi territory, containing 4.5 million citizens.
Many states began to intervene against the Islamic State, in both the Syrian civil war and the War in Iraq (2013–2017), in response to its rapid territorial gains from its 2014 Northern Iraq offensives, universally condemned executions, human rights abuses and the fear of further spillovers of the Syrian Civil War. These efforts are called the war against the Islamic State (ISIS), or the International military intervention against Islamic State (ISIS). In later years, there were also minor interventions by some states against IS-affiliated groups in Nigeria and Libya. All these efforts significantly degraded the Islamic State's capabilities by around 2019–2020. While moderate fighting continues in Syria, as of 2024, ISIS has been contained to a manageably small area and force capability.
On 22 September 2014, the United States officially intervened in the Syrian civil war with the stated aim of fighting the terrorist organization ISIS in support of the international war against it, code named Operation Inherent Resolve. The US currently continues to support the Syrian rebels and the Kurdish-led Syrian Democratic Forces opposed to both the Islamic State and Syrian president Bashar al-Assad.
Opération Chammal is a French military operation in Iraq and Syria launched to help curtail the expansion of the Islamic State of Iraq and the Levant and to support the Iraqi Army. Its name comes from the Shamal, a northwesterly wind that blows over Iraq and the Persian Gulf states.
Operation Shader is the operational code name given to the contribution of the United Kingdom in the ongoing military intervention against the Islamic State of Iraq and the Levant. The operation involves the British Army providing ground support and training to allied forces fighting against ISIL, the Royal Air Force providing humanitarian aid airdrops, reconnaissance and airstrikes, and the Royal Navy providing reconnaissance and airstrikes from the UK Carrier Strike group and escort to allied carrier battle groups.
On 15 June 2014 U.S. President Barack Obama ordered United States forces to be dispatched in response to the Northern Iraq offensive of the Islamic State (IS), as part of Operation Inherent Resolve. At the invitation of the Iraqi government, American troops went to assess Iraqi forces and the threat posed by ISIL.
On 3 October 2014, Canadian Prime Minister Stephen Harper announced that he would put forth a motion to send forces to participate in the coalition for military intervention against ISIL by deploying combat aircraft. On 7 October 2014, the House of Commons approved of sending nine aircraft to join coalition airstrikes against ISIL in Iraq along with 69 special forces advisors to train the Iraqi government's military. The Canadian Armed Forces' contribution to the coalition against ISIL was later dubbed Operation IMPACT. On 30 March 2015, the House of Commons voted to extend the mission to targets in Syria. No additional forces were announced.
Combined Joint Task Force – Operation Inherent Resolve (CJTF–OIR) is a multinational military formation established by the U.S.-led international coalition against the Islamic State with the stated aim to "degrade and destroy" the organization. Led by United States Army Central (ARCENT), it is composed of military forces and personnel from over 30 countries.
The Mosul offensive (2015) was an offensive launched by Kurdish Peshmerga forces on 21 January 2015, with the objective of severing key ISIL supply routes to Mosul, Iraq, and to recapture neighboring areas around Mosul. The effort was supported by US-led coalition airstrikes. The Iraqi Army was widely expected to launch the planned operation to retake the actual city of Mosul in the Spring of 2015, but the offensive was postponed to October 2016, after Ramadi fell to ISIL in May 2015.
This article contains a timeline of events from January 2015 to December 2015 related to the Islamic State of Iraq and the Levant (ISIL/ISIS). This article contains information about events committed by or on behalf of the Islamic State, as well as events performed by groups who oppose them.
The Shirqat offensive, codenamed Operation Conquest or Operation Fatah, was an offensive against the positions of the Islamic State of Iraq and the Levant (ISIL) in and around the district of Al-Shirqat District to reach the city of Mosul.
The Tokhar airstrike occurred on 19 July 2016 in the village of Tokhar, during an offensive by United States-backed forces near the city of Manbij in Aleppo Governorate, and carried out by the United States Air Force. The operation was carried out as part of the American-led intervention in Syria. Reports of the death toll varied, ranging from 56 to 212 civilians being killed with "entire families" pulverized.
The 2017 Mosul airstrike, was an American bombing in the al-Aghawat al-Jadidah neighborhood in western Mosul on 17 March 2017 that killed between 200 and 300 civilians. The incident was the largest single death toll inflicted by a coalition air strike since the 2003 invasion of Iraq by U.S. forces.
The battle of Raqqa (2017), also known as the second battle of Raqqa, was the fifth and final phase of the Raqqa campaign (2016–2017) launched by the Syrian Democratic Forces (SDF) against the Islamic State (ISIL) with an aim to seize the city of Raqqa, the de facto capital of ISIL since 2014. The battle began on 6 June 2017, and was supported by airstrikes and ground troops from the US-led coalition. The operation was named the "Great Battle" by the SDF. It concluded on 17 October 2017, with the SDF fully capturing the city of Raqqa.
The Deir ez-Zor campaign, codenamed the al-Jazeera Storm campaign, was a military operation launched by the Syrian Democratic Forces (SDF) against the Islamic State of Iraq and the Levant (ISIL) in Syria's Deir ez-Zor Governorate in 2017 during the Syrian Civil War with the goal of capturing territory in eastern Syria, particularly east and north of the Euphrates river. The U.S.-led Combined Joint Task Force – Operation Inherent Resolve (CJTF–OIR) anti-ISIL coalition provided extensive air support while SDF personnel composed the majority of the ground forces; OIR special forces and artillery units were also involved in the campaign.
Al-Tanf is a U.S. military base in an American occupied part of the Homs Governorate, Syria. It is located 24km west of the al-Walid border crossing in the Syrian Desert. The surrounding deconfliction zone is located along the Iraq–Syria border and the Jordan–Syria border. The garrison is located along a critical road known as the M2 Baghdad–Damascus Highway. The Rukban refugee camp for internally displaced Syrians is located within the deconfliction zone.
The Battle of Baghuz Fawqani was an offensive by the Syrian Democratic Forces (SDF), assisted by Combined Joint Task Force – Operation Inherent Resolve (CJTF-OIR) coalition airstrikes, artillery, and special forces personnel, that began on 9 February 2019 as part of the Deir ez-Zor campaign of the Syrian Civil War. The battle—which was composed of a series of ground assaults—took place in and around the Syrian town of Al-Baghuz Fawqani in the Middle Euphrates River Valley near the Iraq–Syria border, and was the territorial last stand of the ISIS (IS) in eastern Syria.
The U.S. intervention in the Syrian civil war is the United States-led support of Syrian opposition and Rojava during the course of the Syrian civil war and active military involvement led by the United States and its allies — the militaries of the United Kingdom, France, Jordan, Turkey, Canada, Australia and more — against the Islamic State of Iraq and the Levant (ISIL) and al-Nusra Front since 2014. Since early 2017, the U.S. and other Coalition partners have also targeted the Syrian government and its allies via airstrikes and aircraft shoot-downs.
On 29 December 2019, the United States conducted airstrikes against Kata'ib Hezbollah's weapons depots and command centers in Iraq and Syria, reportedly killing at least 25 militiamen and wounding 55 more. The U.S. Department of Defense said the operation was in retaliation for repeated attacks on Iraqi military bases hosting Operation Inherent Resolve (OIR) coalition forces, particularly the 27 December 2019 attack on a Kirkuk airbase that left an American civilian contractor dead. Kata'ib Hezbollah, an extremist Shi'ite militia funded by Iran, denied any responsibility for the attacks.
On February 25, 2021, the United States military carried out an airstrike on a site which it believed to have been occupied by Iranian-backed Iraqi militias operating from across the border in eastern Syria. The unilateral operation was in retaliation for multiple rocket attacks against U.S. forces in Iraq ten days prior and was the first known offensive military operation carried out under U.S. president Joe Biden.
