Syrian rebels and government troops clashed Sunday in restive districts of Damascus, a monitoring group said, as representatives of the warring sides met for peace talks in Geneva.

“Fierce fighting raged between rebels and troops in Jobar (in eastern Damascus) and the Port Said area of Qadam (in the south),” said the Syrian Observatory for Human Rights.

A rebel mortar round hit the city’s central Qassaa district, wounding seven people, state news agency SANA reported.
