Diyarbakir, Turkey (IINA) - Turkish President Recep Tayyip Erdogan condemned on Saturday what he called the United States’ “support” for Syrian Kurdish groups -the PYD and YPG.

"I condemn U.S support for the PYD and YPG. This is not the promise that was given to us”, Erdogan said at a ceremony at Diyarbakir Airport in eastern Turkey.

He was speaking after Turkey expressed outrage at pictures showing members of U.S Special Forces in Syria wearing YPG insignias and patches. The Pentagon Friday called the patches "unauthorized" and "inappropriate” and that “corrective action” had been taken.

Erdogan said: "I believe that politics must be done honestly. Thus, the friends who believe in us and the ones who stand with us in NATO should not and cannot send their own soldiers to Syria with YPG patches”.

"Those who say: 'We will continue to support the YPG, it is not the PKK'... you are on the wrong side”.

According to Anadolu Agency, the YPG is the armed wing of the PYD – the Syrian offshoot of the PKK, which is designated a terrorist organization by Turkey, the U.S, and the EU.

While Turkey views the PYD and YPG as terrorist groups, Washington continues to support the YPG as an "effective partner" in the fight against ISIS.
