Activists say 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 US government have stopped after the rebels left the area. Rami Abdurrahman, who heads the Britain-based Syrian Observatory for Human Rights, says members of the Division 30 faction fled to a nearby area controlled by a Syrian Kurdish militia. Abu al-Hassan Marea, a Syrian activist who is currently in Turkey near the Syrian border, confirmed Saturday that Division 30 fighters have withdrawn from their headquarters. Friday’s fighting concentrated around the Division 30 headquarters near the northern Syrian town of Azaz. The fighting came days after the Nusra Front detained several members of Division 30, including its commander Col. Nadim al-Hassan.
