U.S. Central Command said American forces and equipment completed their departure from Erbil Air Base on September 30, ending the Operation Inherent Resolve mission in Iraq. Erbil had served as the coalition's main operational hub in the country and hosted most of the roughly 1,500 American and coalition personnel supporting counter-ISIS operations.

The coalition mission began in 2014 after the Islamic State seized large areas of Iraq and Syria. CENTCOM said Iraqi security forces, including the Peshmerga and other forces in the Kurdistan Region, now have the capacity and operational independence to manage threats inside Iraq.

The departure does not end the wider U.S.-led counter-ISIS campaign. Combined Joint Task Force-Operation Inherent Resolve remains operational from its headquarters in Jordan, and U.S. forces continue working with coalition partners and the Syrian government against ISIS in Syria.

President Donald Trump praised the withdrawal, while Iraqi Prime Minister Ali al-Zaidi led a handover ceremony and described it as the start of a new phase centered on Iraqi sovereignty and a different bilateral relationship. The September 30 departure fulfilled the timetable announced by the two governments.
