BEIRUT (AP) — Clashes between members of al-Qaida's branch in Syria and a rebel faction in the country's north believed to have been trained by the U.S. government have stopped after the rebels left their headquarters, activists said Saturday. The fighting came a few days after the U.S. and Turkey announced the outlines of a deal to help rebels push the Islamic State group back from a strip of territory it controls along the Syrian-Turkish border, replacing it with more moderate rebels backed by Washington and Ankara. Rami Abdurrahman, who heads the Britain-based Syrian Observatory for Human Rights, said members of the Division 30 faction fled to a nearby area controlled by a Syrian Kurdish militia.
