U.S. President Obama announced on 10 September 2014 that he would begin to pursue airstrikes in Syria with or without congressional approval.
Starting on 22 September 2014, the U.S., Bahrain, Jordan, Qatar, Saudi Arabia, and the United Arab Emirates began airstrikes against ISIL targets in Syria with fighters, bombers, and sea-based Tomahawk cruise missiles.
Strikes continue to take place in Syria daily.
Additionally, on the first night, U.S. forces launched eight cruise missile strikes against the al-Qaeda-affiliated Khorasan.
In early November early December 2014, the U.S. launched additional airstrikes against the same group.
In November 2014, Morocco sent 3 F-16s to be deployed in UAE, to fight ISIL in Iraq and Syria under U.S.-led operations.

On 24 December 2014, ISIL shot down a Jordanian fighter jet over Syria and captured its pilot, Jordanian air force lieutenant Muath Al-Kasasbeh.
Al-Kasabeh was offered in exchange for captured ISIL fighters.
Jordan offered to make the exchange, but demanded "proof of life" first.
However, Al-Kasabeh had already been executed by immolation.
When video of the pilot's execution was released, a moratorium on executions in Jordan was lifted and the Al-Qaida operatives, Sajida al-Rishawi and Ziad al-Karbouli were executed.

On 21 August 2015, three ISIL fighters, two with UK nationality, were targeted and killed in Raqqa, Syria by a British Royal Air Force MQ-9 Reaper strike.
Prime Minister David Cameron gave a statement to Parliament that one of the British nationals targeted had been plotting attacks in the United Kingdom.
Another British national was killed in a separate air strike by US forces in Raqqa on 24 August.

In October and November 2015, the U.S. intensified its airstrikes on ISIL-held oil facilities in an operation named "Tidal Wave II", after the World War II campaign against Axis oil targets in Romania.
The U.S. strategy aimed "to knock out specific installations for six months to a year" by focusing on facilities near Deir el-Zour.
The Omar oil field, which produced 30,000 barrels of oil per day and $1.7 million to $5.1 million in revenue per month at full capacity, was hit on 21 October, reducing it to roughly a third of its capacity.
French aircraft also participated in the strikes.

On 16 November 2015, a U.S. Operation Tidal Wave II sortie destroyed 116 ISIL fuel tankers clustered near Abu Kamal, a city on the Syrian border with Iraq.
Four A-10 Thunderbolt IIs and two AC-130 Spectre gunships participated in the raid.
Before attacking the trucks the planes conducted several low-level, 'show of force' passes.

On 2 December 2015, the Parliament of the United Kingdom voted in favour (397 to 223) to authorise air strikes in Syria.
Within hours, RAF Tornado jets carried out their first air strikes, targeting the Omar oil fields in eastern Syria, which were under ISIL control.
Tornado GR-4 jets were used for surveillance and a further six Typhoons left RAF Lossiemouth, Scotland to join forces at RAF Akrotiri, Cyrpus.

On 4 December 2015 Germany intervened in reaction to the November 2015 Paris attacks by sending the frigate Augsburg (F213) and Panavia Tornado reconnaissance aircraft to the region.
The Augsburg concluded its first deployment in March 2016, redeploying in September and concluding its mission on 14 November 2016.

On 29 January 2016, the Netherlands announced its intent on expanding its airstrike operations to Syria.
