Beginning in September 2014, the United States started plans to intervene in Syria against the Islamic State (ISIS or ISIL). On 22 September 2014, the United States and Arab partners began to strike targets inside of Syria.
During the Arab Spring, peaceful protests against the Assad administration were suppressed and became violent. Islamist elements quickly came to dominate the rebellion. The most powerful rebel faction transformed into what would become the Islamic State of Iraq and the Levant.
Following the abduction of a number of foreigners in Syria, on 4 July 2014, U.S. air strikes were conducted against the ISIS military base known as the "Osama bin Laden Camp". At the same time, two dozen special operations members parachuted from helicopters near an ISIS building for high-valued prisoners. However, no prisoners were found in the building and the special forces members were soon engaged by ISIS forces from Ar-Raqqah and a three-hour firefight ensued. Eventually, U.S. forces came to the conclusion that the hostages were no longer at the site and abandoned the rescue attempt. At least 5 ISIS fighters were killed and a U.S soldier was wounded. Jordanian forces were also reportedly involved in the operation with one Jordanian soldier also wounded, but this was not confirmed. Later it was reported the hostages had been moved 24 hours before the attempted rescue. It remained unclear whether the operation failed due to bad intelligence or whether ISIS forces were alerted in advance of the mission.
In the aftermath of the operation, three hostages were executed over a one-month period: Americans James Foley and Steven Sotloff and Briton David Haines.
Surveillance flights over Syria
On 26 August, the U.S. began sending surveillance flights, including drones, into Syria to gather intelligence on ISIS targets in Syria. The flights started gathering intelligence that would aid any future U.S. airstrikes, however airstrikes were not yet authorized. No approval was sought from the Syrian Arab Republic for the flights entering Syrian airspace.
At the direction of President Obama, the American Central Intelligence Agency played an active role since the early stages of the Syrian Civil War. The U.S. originally supplied the moderate rebels of the Free Syrian Army with non-lethal aid but soon escalated to providing training, cash and intelligence to selected rebel commanders.
On 17 September, the House of Representatives voted to authorize the executive branch to train and arm Syrian rebels against ISIS forces. One of the groups that United States intends to train and arm is the Islamist Army of Mujahedeen.
Preparations
In his address to the nation on 10 September, U. S. president Barack Obama announced that the United States were going to bomb ISIS in Syria and to train rebels. For the first time he authorised direct attacks against the militant group in Syria. In his address he said that the United States are going on offensive launching "a steady, relentless effort to take out" the jihadist group that has seized vast swaths of Iraq and has a large safe haven in Syria, "wherever they exist." Obama also announced creating of a broader coalition against the ISIS.
Commenting his adress, Russian Foreign Ministry spokesman Alexander Lukashevich opposed the U. S. intervention against the ISIS "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 17 September, the U. S. House of Representatives gave bipartisan approval to Obama's plan to train and arm the Syrian rebels in their fight against the ISIS. In a statement after the House vote, Obama said that the United States won't send military troops to Syria. The U. S. top military leadership approved Obama's plan on 18 September. The Senate gave final congressional approval to Obama's proposal the next day.
The Spokesperson for the United States Department of State, Jen Psaki, told that the United States didn't asked for Syrian permission to start the intervention or made coordinated actions with the Syrian government, but the United States warned Syria not to engage U. S. aircraft. The United States didn't gave any advance notification to the Syrians at a a military level, or give any indication of our timing on specific targets. However, Syrian foreign ministry said that the United States did inform the Syrian envoy to the United Nations before launching airstrikes against the ISIS.
Air campaign
Multi-national airstrikes
On 22 September, Pentagon Press Secretary Rear Admiral John Kirby confirmed that the United States and other partner nations had undertaken strikes in Syria using fighter, bomber, and Tomahawk missile's authorized by President Barack Obama. Bahrain, Jordan, Qatar, Saudi Arabia and the United Arab Emirates were identified as countries making or supporting airstrikes the first night. The initial strikes were coordinated by United States Central Command and targeted about 20 Islamic State targets, including headquarters buildings. Anti-Islamic State 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 Raqqa province.
The US also targeted the al Qaeda affiliated Al-Nusra Front and Khorasan Group in the Aleppo and Idlib governorates of Syria.. These organizations are not part of ISIS.
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 since entering service in 2005.
At least 70 IS fighters, 50 fighters affiliated with al Qaeda and civilians were killed overnight by the strikes according to the SOHR. Eight strikes were launched against the group Khorasan.
Syrian government involvement
Syria's government did not request or approve the airstrikes, although it is fighting ISIS militants. Assad's military possesses sophisticated anti-aircraft missiles, mostly near the capital of Damascus and the border with Israel and not in ISIL controlled areas. Syria stated they were advised by the US the day before of the air strikes.
