Ankara hinted on Friday it could attack US forces in the northeast of Syria if Washington continues to provide Kurdish People’s Protection Units (YPG) with weapons.
The Turkish position came while the Syrian Democratic Forces (SDF), which includes YPG members and Arab fighters, are about to oust ISIS from the “Euphrates Dam,” the third largest dam in Syria.
