US-led coalition forces returned fire after being repeatedly shot at near Manbij in north Syria where they are patrolling near areas held by Turkey-backed rebels, the 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 US-led coalition forces "is not acceptable", Dillon said.
