Turkey on Wednesday summoned a top U.S. diplomat in Ankara to protest Washington's support of a Kurdish militia in Syria, sources in the Turkish foreign ministry said, the latest in a long-standing disagreement between the NATO allies.
The Turkish foreign ministry summoned the U.S. charge d'affaires to voice its displeasure over Washington's arming and training of the YPG Syrian Kurdish militia in Syria, the sources said.
Turkey and the United States have been at loggerheads over Washington's policy of support for the YPG, which Ankara views as an extension of the Kurdistan Workers Party (PKK) that has waged an insurgency in Turkey's largely Kurdish southeast for more than three decades.
The YPG is the main element in a force that Washington has assisted with training, weapons, air support and help from ground advisers in the battle against Islamic State.
Last month the YPG militia said it had fully captured Deir al-Zor's eastern countryside from Islamic State with the help of both the U.S.-led coalition and Russia.
