In September 2014, the Islamic State of Iraq and the Levant launched the Siege of Kobanî and entered the city by October. This partly contributed to the beginning of the American-led intervention in Syria, which launched airstrikes and airdropped supplies and weapons to the YPG in Kobanî, some of which have been captured by ISIL. The FSA was divided in its position on the YPG, with one of the FSA commanders, Malik al-Kurdi, a former Syrian Navy colonel, describing the US support for the YPG as "disgusting". However, the FSA groups Northern Sun Battalion, Liwa Thuwwar al-Raqqa, and Jabhat al-Akrad cooperated with the YPG and formed the Euphrates Volcano joint operations room in fighting ISIL and lost 70 fighters in the fighting. After ISIL was expelled from the city in late January 2015 the FSA's Dawn of Freedom Brigades jointly raised their flag along with the YPG and YPJ above the hills of Kobanî.
