The U.S.-led coalition forces exchanged fire with Turkey-backed Free Syrian Army (FSA) fighters near Manbij in north Syria while they were patrolling, coalition spokesman Colonel Ryan Dillon said on Tuesday.
"Our forces did receive fire and return fire and then moved to a secure location," he said by phone.
"The coalition has told Turkey to tell the rebels it backs there that firing on U.S.-led coalition forces is not acceptable," Dillon said.
