The U.S. military intends to remain in the northern Syrian city of Manbij despite an incoming offensive backed by Turkey, which, along with Ankara's rebel allies, has launched an assault on nearby Kurdish forces sponsored by the Pentagon.
With the Islamic State militant group (ISIS) mostly defeated in the east, the focus of Syria's nearly seven-year war has shifted west, particularly to the northwestern district of Afrin, where Turkey and the insurgent Free Syrian Army have begun attacking a Kurdish militia known as the People's Protection Units (YPG). The YPG was the primary faction behind the Syrian Democratic Forces that led U.S. efforts to destroy ISIS on the ground, but it also was considered a terrorist organization by Turkey because of its alleged links to a Kurdish nationalist insurgency at home.
