Turkish President Recep Tayyip Erdogan on Saturday condemned Washington and accused the United States of not being "honest" about its alliance with the Kurdish People's Protection Units (YPG).
"The support they give to... the YPG (militia)... I condemn it," Erdogan said in a speech he delivered in the mostly Kurdish city of Diyarbakir in Turkey's southeast.
"Those who are our friends, who are with us in NATO, should not and cannot send their soldiers to Syria wearing YPG insignia."
US commandos in Syria were this week photographed wearing YPG patches on their uniforms. Keen to avoid a rift with Turkey, a US military spokesman said Friday that American troops were not authorized to wear the emblems and had been ordered to remove them.
