"The new rupture in Turkish-Syrian relations came as reports of a possible new mass killing emerged Friday in Syria’s northern Aleppo Province. Opposition activists said those killings, in the village of Daret Azzeh, were the outcome of a military skirmish in which soldiers of the Free Syrian Army, the main armed rebel force, carried out a surprise attack on a group that included suspected members of the shabiha, the feared pro-government militia accused by the opposition of complicity in numerous killings, detentions and torture. At least 25 men were shot to death. “The armed opposition in the area ambushed a number of cars,” said the Syrian Observatory for Human Rights, an antigovernment group based in Britain with networks of contacts inside Syria. A video that the Observatory posted online from activists, said to have been recorded in Daret Azzeh, showed carnage, with bloodied corpses piled around a white pickup truck riddled with bullet holes. Many corpses were clothed in military fatigues or black clothes, a trademark of the shabiha."
