BEIRUT (AP) — Row upon row of bloodied bodies wrapped in colorful blankets laid out on a mosque floor in a Damascus suburb. Long narrow graves tightly packed with dozens of victims. Nestled among them, two babies were wrapped in a single blood-soaked blanket, a yellow pacifier dangling beside them from a palm frond.

Evidence mounted on Sunday of a new massacre in Syria’s deepening civil war, with activists reporting a killing spree by government forces after they seized the suburb of Daraya from rebel control three days ago. Reports of the death toll ranged from more than 300 to as many as 600.
