US soldiers in northern Syria have been ordered to remove from their uniforms the insignia of the main Kurdish militia in the country, a Pentagon spokesman says.
"Wearing those YPG patches was unauthorized and it was inappropriate," Army Colonel Steven Warren says. "Corrective action has been taken."
Warren says the soldiers are part of a contingent of more than 200 US "advisers" in Syria working with the Syrian-Arab coalition in the fight against Islamic State.
He says US special forces have a history of wearing such insignia when they are partnering with forces around the world. But it isn't authorized, he says, and in this case the soldiers were told to remove the patches.
