BEIRUT, Shawwal 14, 1433, Sep 1, 2012, SPA - Syrian activists say regime troops are shelling neighborhoods in Damascus after overnight clashes with opposing fighters. The Britain-based Syrian Observatory for Human Rights says the bombardment of the southern neighborhood of Tadamon early Saturday followed street fighting with opposing fighters there. Another activist group, the Local Coordination Committees, says troops also shelled the nearby neighborhood of Hajar Aswad. Activists say more than 20,000 people have been killed since the uprising against President Bashar Assad's regime began in March last year. --SPA 13:06 LOCAL TIME 10:06 GMT www.spa.gov.sa/1026072
