During the Syrian Civil War, which began in 2011, the United States first supplied the rebels of the Free Syrian Army with non-lethal aid (including food rations and pickup trucks), but quickly began providing training, cash, and intelligence to selected Syrian rebel commanders to fund a proxy force against the sovereign state of Syria.

The United States began surveillance missions on ISIL positions in Syria in September 2014. On September 10, President Barack Obama gave a speech indicating his intent to "degrade and ultimately destroy" Islamic State of Iraq and the Levant (ISIL), saying, "I have made it clear that we will hunt down terrorists who threaten our country, wherever they are. That means I will not hesitate to take action against ISIL in Syria, as well as Iraq."

On September 22, 2014, the United States, Bahrain, Jordan, Qatar, Saudi Arabia, and the United Arab Emirates began to strike targets of the Islamic State of Iraq and the Levant (ISIL) inside Syria, as well as the Khorasan group in the Idlib Governorate to the west of Aleppo, and the al-Nusra Front around Ar-Raqqah, as part of the Military intervention against ISIL.

On November 2, 2015, in response to the intervention, representatives from Ahrar ash-Sham attended a meeting with the al-Nusra Front, the Khorasan Group, the ISIL, and Jund al-Aqsa, which sought to unite several hard-line groups against the US-led coalition and other moderate Syrian rebel groups. On November 6, a US airstrike struck Ahrar ash-Sham at its headquarters in Idlib. By 14 November 2014, it was revealed that the negotiations between al-Nusra, Jund al-Aqsa, ISIL and Ahrar ash-Sham had failed.

Background

Further information: Arab Spring, Arab Winter, and Syrian Civil War

Following the start of the Arab Spring in 2011, protests in Syria against the Assad administration were suppressed and became violent. In 2012, the al-Nusra Front was established by the Islamic State of Iraq as the official branch of al-Qaeda in Syria. The al-Nusra Front was eclipsed by its own creator, and al-Qaeda severed its ties to the Islamic State of Iraq and the Levant in February 2014, after an eight-month power struggle.

Arming and training the Syrian opposition

Further information: Foreign involvement in the Syrian Civil War § United States

Further information: Syrian Train and Equip Program

At the direction of U.S. President Barack Obama, the Central Intelligence Agency (CIA) was put in charge of the operations, worth about $1 billion annually, to arm anti-government forces in Syria, an operation which began in 2013, more than two years after the start of the civil war in 2011. Prior to 2013, the CIA only supplied the apparently moderate rebels of the Free Syrian Army with non-lethal aid, but later began providing training, cash, and intelligence to selected rebel commanders.

While the CIA-run programs to arm and train Syrian opposition factions began 2013, on September 17, 2014 the House of Representatives voted to authorize the executive branch to train-and-equip Syrian rebels against ISIL forces. One of the groups that United States intended to train-and-equip was the Islamist Army of Mujahedeen while the Harakat Hazm group was already being supplied. There were indications that the Army of Mujahedeen was still being vetted for support. The United States was set to send 400 troops and hundreds of support staff to countries neighboring Syria to train 5,000 opposition soldiers a year for the next three years. The countries taking part in the train-and-equip program were to include Jordan, Qatar, Saudi Arabia, and Turkey. The Pentagon confirmed that it had selected 1,200 Syrian opposition members to begin training in March 2015, with 3,000 to complete training by the end of 2015. However of that number only about 200 actually began training, the majority of whom left after being required to agree to fight only against ISIL and not the Assad government. As of mid-2015, only a group of 54 such fighters (Division 30) had been deployed, which was quickly routed by al-Nusra.

The successful experience in Kobanî had informed U.S. policy in regards to arming Syrian opposition groups other than the Kurdish YPG, with plans to give other groups technicals equipped with radio and GPS equipment to call in airstrikes. John R. Allen, President Obama's envoy to the international coalition against ISIL, has said "It is clearly part of our plan, that not only we will train them, and we will equip them with the latest weapons systems, but we will also protect them when the time comes," alluding to aiding the opposition with air support and no fly zones. The United Kingdom announced it will send around 75 military instructors to train Syrian opposition forces. The train-and-equip programme started on 9 May. On 25 May, Turkey and the U.S. agreed "in principle" on the necessity to support these forces with air support.

July 2014 rescue mission

Main article: 2014 American rescue mission in Syria

Following the abduction of a number of foreigners in Syria, on July 4, 2014, the U.S. carried out an operation to rescue foreign hostages being held by ISIL. U.S. airstrikes were conducted against an ISIL military base known as the "Osama bin Laden Camp" while at the same time, two dozen special operations members parachuted from helicopters near an ISIS building for high-valued prisoners. No prisoners were found in the building and the special operations members were quickly engaged by ISIL forces dispatched from Ar-Raqqah, which started a three-hour firefight. U.S. forces concluded that the hostages were no longer at the site and abandoned the rescue attempt. At least five ISIL fighters were killed and one U.S. soldier was wounded. Jordanian forces were also reportedly involved in the operation, with one Jordanian soldier reportedly wounded, but Jordanian involvement was not confirmed. Later on, it was reported that the hostages had been moved 24 hours before the attempted rescue. Following the mission, it was still unclear whether the operation failed due to bad intelligence or whether ISIL forces were alerted in advance of the mission.

Beheadings of Western hostages

In the aftermath of the rescue mission, and purportedly as a response to airstrikes in Iraq, ISIL beheaded three hostages over a one-month period: Americans James Foley on August 19, 2014, Steven Sotloff on September 2, and Briton David Haines on September 13.

Surveillance flights over Syria

On August 26, 2014, the U.S. began sending surveillance flights, including drones, over Syria to gather intelligence on ISIL targets in Syria. The flights began gathering intelligence that would aid future airstrikes; however, airstrikes were not yet authorized at that point, and no approval was sought from the Assad government for flights entering Syrian airspace.

International coalitions against ISIL

Main article: Military intervention against ISIL § International coalitions against ISIL

On 5 September, 15 September and 3 December 2014, different sets of countries came together to discuss concerted action against ISIL. Present at all three meetings were the United States, United Kingdom, France, Germany, Italy, Canada, Turkey and Denmark.

The coalition of 5 September (10 countries) decided to support anti-ISIL forces in Iraq and Syria.
A coalition of 3 December 2014 (59 countries) agreed on a many-sided strategy against ISIL, including cutting off ISIL’s financing and funding and exposing ISIL’s true nature.

Training Syrian moderate opposition to fight ISIL

Main article: Syrian Train and Equip Program

In late 2013 the United States began a program to train and equip Syrian "moderate rebels". In July 2015 the first class of 54 US-backed rebels were inserted into Syria from Turkey. Within days, virtually all of the US-backed rebels were dead or missing, and their leader had been captured by the Al-Queda-affiliated al-Nusra Front.

In March 2015, the United Kingdom announced that it would provide military training to Syrian moderate opposition forces, to enable them to defend Syrian communities against ISIL, and later also lead offensives against ISIL.

Multinational air war

Preparations for American airstrikes

In his address to the nation on September 10, 2014, U.S. President Obama announced his intention to bomb ISIL targets in Syria and called on Congress to authorize a program to train and arm rebels who were fighting ISIL and the Syrian forces of Bashar al-Assad. For the first time, he authorized direct attacks against the militant group in Syria. In his address, he said the United States were going on offensive, launching "a steady, relentless effort to take out" the group "wherever they exist." Obama also announced creating of a broader coalition against ISIL.

Commenting on Obama's address, Russian Foreign Ministry spokesman Alexander Lukashevich opposed the U.S. intervention against ISIL in Syria "without the consent of the legitimate government" and said that "this step, in the absence of a UN Security Council decision, would be an act of aggression, a gross violation of international law". Ali Haidar, Syrian minister of national reconciliation, said that "any action of any kind without the consent of the Syrian government would be an attack on Syria".

On September 17, the U.S. House of Representatives approved Obama's plan to train and arm the Syrian rebels in their fight against ISIL. In a statement following the House vote, Obama said that the United States wouldn't send military troops to Syria. The Senate gave final congressional approval to Obama's proposal the next day.

The U.S. did not request permission from the Syrian government, nor did it coordinate its actions with the Syrian government, provide direct notification to the Syrian military or give indication of timing on specific targets, but it did notify the Syrian U.N. representative, which the Syrian government confirmed.

Before the airstrikes began, the United States also informed Iran, the Assad government's largest regional ally, of their intention to launch airstrikes. It did not share specific timing or targets of strikes with the Iranian government but reportedly assured it that the US would not strike any Syrian government targets.

Map of the first round of U.S. and coalition strikes in Syria

September 2014

On September 22, Pentagon Press Secretary Rear Admiral John Kirby confirmed that the United States and other partner nations had undertaken strikes in Syria using fighters, bombers, and Tomahawk missiles in strikes authorized by President Barack Obama. Bahrain, Jordan, Qatar, Saudi Arabia and the United Arab Emirates were identified as countries conducting or supporting airstrikes the first night. The initial strikes were coordinated by United States Central Command and targeted about 20 Islamic State of Iraq and the Levant targets, including headquarters buildings. Sources in Syria claimed that among the targets was also Brigade 93, a Syrian army base that the militants had recently captured and targets in the towns of Tabqa and Tel Abyad in Ar-Raqqah Province.

The US also targeted the al-Qaeda-affiliated al-Nusra Front and the Khorasan Group in the Aleppo and Idlib Governorates of Syria.

F-22 Raptor stealth fighters were reported to be among the U.S. aircraft striking targets in Syria on the first night of the campaign, carrying out their first combat missions ever since entering service in 2005.

At least 70 ISIL fighters, 50 fighters affiliated with al-Qaeda, and an unknown number of civilians were killed overnight by the airstrikes, according to the Syrian Observatory for Human Rights while eight strikes were launched against the Khorasan group.

On September 24, the United States and coalition partners conducted a second round of airstrikes on ISIL facilities in Syria. The airstrikes were targeting oil production facilities controlled by ISIL who had been using the oil in order to fund their activities. Some targets were apparently also mobile production facilities which were most likely not refineries.

In a third round of airstrikes on ISIL targets on September 25, Arab partners lead the United States in strikes against militant-held oil facilities in northeastern Syria. Saudi Arabia and the United Arab Emirates dropped 80 percent of the bomb tonnage in the third round of strikes, compared to other strikes in which the United States lead Arab partners.

The siege by Islamic State fighters had recently forced over 100,000 Syrian Kurds to flee across the border to Turkey.

On September 28 and 29, the United States carried out two rounds of strikes against IS positions across Syria in 4 provinces. Among the facilities targeted was the entrance to the largest gas plant in Syria, in the Deir ez-Zor Province, and ISIL training camp and vehicles near an ISIL controlled grain silo in Manbij, Aleppo province.

October 2014

In an eighth round of airstrikes in Syria on October 1, the United States and coalition partners struck ISIL targets in Northern Syria.

Airstrikes on the Khorasan Group

Play media

One of the groups targeted by U.S. airstrikes was the Khorasan Group, an extremist group of suspected al-Qaeda "core" members who were alleged to have been plotting an attack against the U.S. and other Western nations. The strikes targeted Khorasan training camps, explosives and munitions production facilities, communications facilities, as well as command and control facilities. The group has been claimed to possess advanced bomb making skills and their plot is claimed to involve a bomb made of a nonmetallic device such as a toothpaste container or clothes dipped in explosive material. The group is reportedly led by Muhsin al-Fadhli, a leader of al-Qaeda and a close confidant of Osama bin Laden. Intelligence officials expressed concern that the group may include militants who were taught by Ibrahim al-Asiri, the chief bomb maker for al-Qaeda in the Arabian Peninsula, who is known for his sophisticated bomb making techniques that nearly downed two Western airliners.

Later statements by government officials indicated that the threat of a plot may have been less severe than initially reported. One official indicated that "there did not yet seem to be a concrete plan in the works", while another told The Guardian that "there was no indication of an imminent domestic threat from the group" at the time the United States began bombing.

On November 6, a second round of airstrikes was launched against Khorasan and al-Nusra in northwestern Syria, along with Ahrar ash-Sham at its headquarters in Idlib, whose leadership had been infiltrated by al-Qaeda. On November 13, 2014, the US launched a third set of airstrikes against Khorasan. On November 19, the US carried out another airstrike on Khorasan near Hazm, which struck and destroyed a storage facility associated with the group. On December 1, the US carried out another airstrike on Khorasan near Aleppo.

On 24 March 2015, it was revealed that the US airstrikes on Khorasan had killed 17 militants from the group.

On 8 July 2015, a US airstrike near the town of Sarmada in Idlib, Syria, killed Muhsin al-Fadhli, the leader of Khorasan.

Syrian reaction to the airstrikes

Syrian military radar was “passive” during the first air strikes, with no attempt to counter US aircraft. During the first night of airstrikes, the United States' force deployed with HARM missiles as a precaution, as it was uncertain how Syria's air-defense network would react.

Civilian casualties

The website Airwars which "maintains an extensive database of all known allegations in which civilians and friendly forces have been reported killed by the Coalition since August 2014" reports between 503 and 700 civilians killed by Coalition airstrikes in Syria as of April 2016.

On September 29, 2014, several groups including the Syrian Observatory for Human Rights, the Aleppo Media Center, and the Local Coordination Committees reported that U.S. strikes hit a grain silo in the ISIL-controlled town of Manbij in northern Syria, killing two civilians.

The Syrian Observatory for Human Rights reported ten airstrikes, also targeting various parts of the province of Idlib, killed at least one child and six other civilians. The group said at least 19 civilians had been killed in coalition airstrikes at that time. The Pentagon reported it had no evidence of any civilian casualties from airstrikes targeting militants in Syria. The United States has also acknowledged that its rules to avoid civilian casualties are looser in Syria than those for drone strikes elsewhere.

The SOHR and other activist groups, reported that seven civilians were killed when an air strike hit a gas distribution facility near the town of al-Khasham is the eastern Deir al-Zor province on October 17, 2014 and three civilians were killed in an air strike on October 16, 2014 in the north east province of al-Hassakah. According to their reports, most of the civilians killed were fuel tanker drivers.

According to Reuters, 50 civilians were killed in Syria by US-led airstrikes, since the start of the campaign in late September 2014. On December 28, 2014, a U.S. airstrike in the northern Syrian town of Al-Bab killed more than 50 civilians.

On May 21, 2015, the United States admitted it "probably" killed two children in bombings near Harem on November 4 and 5, 2014. These are the first such admissions of the campaign, and followed a military investigation. A similar investigation regarding an event in Syria is underway, and two regarding events in Iraq. Two adult civilians were also minorly injured in the Harem strikes. The deaths and injuries are attributed by the military investigation to unintentional secondary explosions, after the bombers hit their intended targets, linked to the Khorasan.

Results

According to CJTF-OIR, ISIL has lost 20% of the territory it possessed in Syria since the campaign began, mostly due to advances by YPG/SDF forces with heavy Coalition air support. Overall the American-led air campaign against ISIL is estimated by the Pentagon to have struck 23,000 targets (including 140 tanks, 400 Humvees, and 1,300 pieces of oil infrastructure) and killed 27,000 militants, with approximately 1/3 of these losses taking place in Syria.

Air supply

On October 20, 2014 the United States began airdropping supplies to Syrian Kurdish forces, including the YPG, in Kobanî. The Kurdish forces there have been engaged in battle with ISIL during the Siege of Kobanî. Prior to October 20, the United States and its coalition partners fighting against ISIL in Syria, had not provided any supplies to Kurdish forces in their fight against ISIL. Much of the reason for US having to airdrop supplies was due to the Turkish government's refusal to allow supplies to pass through their border into Kobanî. The U.S. specifically airdropped weapons, ammunition, and medical supplies supplied by Iraqi Kurdistan specifically to supply the Kurdish forces in Syria. On October 21, a video was released by ISIL showing what it claimed was a bundle of airdropped small arms, ammunition, and other supplies from the United States. The Pentagon said it was analyzing the video and could not at the time confirm whether the video was authentic but that the materials were similar and video would be analyzed by the Department of Defense to analyze its authenticity. On October 22, the Pentagon confirmed that one of the airdrops had been intercepted by ISIL but that it most likely would not give ISIL any real advantage in their operations.

Ground forces

During the beginning of the coalition interventions, leaders including U.S. President Obama, said coalition ground forces would not be used in the fight against ISIL either in Iraq or Syria unless they were local coalition forces. While in Iraq thousands of coalition troops from the United States and other nations have been deployed in an advisory capacity, in Syria no ground troops from the coalition intervening in Syria were deployed in the beginning of the intervention.

While there were no coalition ground forces in Syria originally, the US government has said that it wants to spend $500 million to fund the training and arming of up to 5,000 moderate rebels to function as ground forces against ISIL. Under the original plan, the rebels would be trained in Saudi Arabia and other unnamed countries and then return to fight in Syria. The 'moderate' opposition groups that are expected to be armed and trained by the US government include the Free Syrian Army, which is a network of hundreds of smaller rebel groups along with the Syria Revolutionaries Front. In mid-September 2014, the US Congress approved the plan to arm and fund rebels in Syria. In October 2014, the Turkish government agreed to help train and equip some moderate Syrian rebels in Turkey. The Turkish government agreed to allow the training of at least 2,000 moderate rebels in Turkey by U.S. and Turkish special forces with the rebels being trained in groups of 400. According to Turkish officials, the rebels would be chosen by the country’s MIT intelligence service using its databases in order to select and screen an initial 2,000 rebels to undergo training.

As the Siege of Kobanî continued there were growing calls to also arm the YPG, also known as the People's Protection Units, a Kurdish fighting force in Syria heavily involved in the defense of Kobanî. On October 20, 2014, the Turkish foreign minister, Mevlüt Çavuşoğlu announced that the Turkish government would be allowing peshmerga from the Iraqi Kurdistan Regional Government to cross their border into Kobanî to support Kurdish fighters. The change in policy came after the Turkish government had refused to allow Kurdish fighters and supplies to pass through the border to YPG units in Kobanî, as it viewed the YPG as an offshoot of the PKK. On October 28, Peshmerga from the Iraqi Kurdistan Regional Government departed Erbil to travel to Turkey and eventually to Kobanî. A total of 152 soldiers were deployed starting with forty vehicles carrying weapons, artillery, and machine guns, along with 80 Peshmerga forces, who crossed the border into Turkey by land with the heavy weapons and then drove to the border near Kobanî. The other 72 soldiers in the contingent flew to Turkey and rejoined the rest of the contingent on October 29. On October 29, 152 Kurdish Peshmerga from Iraq and 50 Free Syrian Army fighters crossed the border into Kobanî with heavy weapons, small arms, and ammunition.

In November 2015, The Obama administration began the deployment of U.S. special forces to Syria, on the mission of assisting anti-Assad rebel forces in their fight, President Obama then ordered several dozen Special Operations troops into Kurdish-controlled territory in northern Syria to assist local fighters battling the Islamic State, authorizing the first open-ended mission by American ground forces into the country.

In March 2016, it was revealed that British forces had helped in the building up of a mechanised battalion in southern Syria, consisting of tribal fighters to combat Bashar al-Assad’s army.

Naming of Operation Inherent Resolve

Unlike previous U.S. combat operations, no name had been given to the American intervention in Syria and Iraq until it was announced in mid-October that the operational name would be Inherent Resolve. The decision to keep the conflict nameless drew considerable media criticism.

Turkish involvement

Main article: Turkish involvement in the Syrian Civil War

Turkey, a NATO member, has been involved in the Syrian Civil War since the beginning of hostilities. Turkey has trained and armed some members of the Free Syrian Army, and has been involved in certain spillover incidents, however so far Turkey has not been involved in direct combat. On October 2, 2014, the Turkish Parliament authorized direct military action in both Iraq and Syria including using military force in Syria and Iraq as well as allowing coalition members to use bases in Turkey. Turkey has also stationed troops and tanks on its southern border near the Syrian border city of Kobanî. The Turkish government demanded several things to go along with them intervening against ISIL, including a buffer zone in Northern Syria, a no-fly zone over certain parts of northern Syria, ground troops from other countries, and the training of moderate opposition forces to fight both ISIL and al-Assad.

Turkey also holds sovereignty over the Tomb of Suleyman Shah 35 km inside Syria, where it maintains a small garrison of Special forces that is surrounded by ISIL-controlled territory.

On 22 February 2015, the Turkish Army mounted a rescue operation across the border to evacuate its soldiers from the Tomb of Suleyman Shah, an exclave of Turkey south of Kobanî. The Turkish convoy reportedly transited through Kurdish-held Kobanî en route to the tomb. One Turkish soldier was killed in what Ankara described as an accident. The success of the operation was announced 22 February by Turkish Prime Minister Ahmet Davutoğlu.

• Russia – Alexander Lukashevich, Russian Foreign Ministry spokesman, opposed the military intervention "without the consent of the legitimate government" and said that "this step, in the absence of a UN Security Council decision, would be an act of aggression, a gross violation of international law". On 14 October, Russian Foreign Minister Sergey Lavrov questioned the motives of the intervention, saying “Maybe their stated goal is not entirely sincere? Maybe it is regime change?” He also questioned the effectiveness of the year long campaign “With, as far as I know, 25,000 sorties they [US-led air campaign] could have smashed the entire [country of] Syria into smithereens,” continuing to remark that "positive results 'on the ground' are not visible". He also criticized the continued supply of arms to rebels, saying “I want to be honest, we barely have any doubt that at least a considerable part of these weapons will fall into the terrorists’ hands.” He continued to call for the countries involved to join a coalition made up of Russian, Syrian, Iranian, Iraqi, Jordanian and Hezbollah forces against what Russia claims is solely ISIL and al Qaeda, but the US has asserted is primarily non-jihadist opposition forces.
• Turkey – The Davutoglu Government called on the Grand National Assembly of Turkey to approve measures that would grant extensive authority to the President to launch military operations in both Syria and Iraq, including the authority to send troops across the border, although it is unclear whether the Turkish leadership intends to act on that authority.

Syrian reactions

• Syria – A week before the first airstrikes, Ali Haidar, the Syrian Minister of National Reconciliation, said that "any action of any kind without the consent of the Syrian government would be an attack on Syria". However, despite Haidar's original statement, after the coalition campaign began, the Syrian government struck a more conciliatory tone with Foreign Minister Walid al-Moallem suggesting the airstrikes were an indication that Syria and the anti-ISIL coalition were on the same side.
• Syrian opposition – Hadi Bahra, the leader of the National Coalition for Syrian Revolutionary and Opposition Forces called for airstrikes against ISIL before the intervention began. The coalition is recognized by 20 countries, the European Union, and the Arab league as the legitimate representative of Syria in opposition to the Assad government. Bahra said strikes were needed to weaken ISIL, a faction in the inter-rebel conflict during the Syrian Civil War, so that the Free Syrian Army and other moderate opposition forces could oppose Assad more effectively. Despite Bahra's support, many Syrian rebel groups have criticized U.S. airstrikes for targeting only ISIL who are enemies of the Assad government, while not also targeting Assad government forces, the results of which could help government forces gain more ground. Meanwhile, jihadist groups within the opposition have portrayed the coalition as an anti-Sunni stooge of the Syrian regime, while many Sunnis in Syria are angered that only extremist Sunnis are being targeted while mostly Shiite Assad forces aren't targeted. Some rebels defected to extremist groups as a result of the U.S. decision to strike jihadist groups other than ISIL, such as the al-Nusra Front.
