US troops left two observation posts in NE Syria after a phone call Sunday night between President Donald Trump and Turkish President Recep Erdogan. US sources reported that they agreed that American forces would stand aside for the coming Turkish military operation in the region, start their pullback and refrain from interfering if fighting broke out between the Turkish invaders and the Kurds of the US-backed SDF militia. US sources added that the two presidents agreed to meet next month, indicating that the Turks would delay their offensive until then. DEBKAfile adds: The first Turkish target is the conquest of Tel Abyad, a town on the Syrian-Turkish border which is not a Kurdish area. However, Kurdish sources accuse the Trump administration of abandoning their fighters to Turkish assault against its commitments, after they fought alongside American forces to oust ISIS from its Syrian strongholds.
