The massacre occurred in the suburb of Douma, leaving 13 people dead, including nine men, three children and a woman, Xinhua reported.
Syria has been experiencing unrest since March 2011 with organized attacks by well-armed gangs against Syrian police forces and border guards being reported across the country.
In October 2011, calm was eventually restored in the Arab state after President Assad started a reform initiative in the country, but Israel, the US and its Arab allies are seeking hard to bring the country into chaos through any possible means. Tel Aviv, Washington and some Arab capitals have been staging various plots in the hope of stirring unrests in Syria once again.
The US and its western and regional allies have long sought to topple Bashar al-Assad and his ruling system. Media reports said that the Syrian rebels and terrorist groups have received significantly more and better weapons in recent weeks, a crime paid for by the Persian Gulf Arab states and coordinated by the United States.
