A rights group said Syrian rebels killed 23 members of forces loyal to President Bashar al-Assad Monday. Shelling of the town of Rastan by pro-Assad forces continued, the rights group said, killing nine people. Fifteen miles north of the city of Homs, the site of heavy shelling in past months, Rastan is a hotspot that has changed hands multiple times as opposition and Syrian military forces battle for control. “Shells and rockets have been hitting the town since 3 a.m. at a rate of one a minute,” a member of the Free Syrian Army told Reuters. “Rastan has been destroyed.” The shelling reportedly began Sunday evening and became increasingly intense, leaving a rebel commander among the dead, sources said.
