Day Marred by Violence in Syria

More than usual, that is

BEIRUT, Lebanon — Violence raged across Syria on Sunday as government forces killed dozens of rebels in an ambush east of Damascus, fighters linked to Al Qaeda battled Kurdish militias and Syria's military peppered an outdoor market with mortar rounds.

Antigovernment activists also accused government forces of killing 13 members of a family in northwestern Syria.

In the day's deadliest attack, government forces ambushed a group of rebel fighters in the town of Adra, northeast of Damascus, and left dozens of dead bodies lying in the sand, according to video broadcast on Al Manar, a television station run by Hezbollah, the Lebanese militant group and political party that supports President Bashar al-Assad.
