Yarmouk-camp in Damascus shelled: at least 20 people killed

The Syrian army shelled rebel positions inside a Palestinian refugee camp on the edge of Damascus on Sunday killing at least 20 people, opposition campaigners said.
The Yarmouk camp, adjacent to the capital's southern entrance, has been shelled before.The reasons is tensions between the Popular Front for the Liberation of Palestine-General Command (PFLP-GC), headed by Palestinian Ahmad Jibreel and other factions. The PFLP-GC supports the regime of president and patrols the camp with armed units. Some rebels said last week they had begun arming sympathetic Palestinians to fight the PFLP-GC, which has helped Assad in his crackdown on the 19-month-old revolt. Apparently the Syrian army responded to this development.
