Turkish President Recep Tayyip Erdogan on Saturday condemned the United States' support of Kurdish fighters in Syria after AFP pictures revealed US commandos wearing the insignia of a militia branded a terror group by Ankara. 

"The support they give to... the YPG (militia)... I condemn it," said Erdogan. "Those who are our friends, who are with us in NATO... cannot, must not send their soldiers to Syria wearing YPG insignia."
