BEIRUT Dec 16 (Reuters) - Syrian fighter jets rocketed the Palestinian Yarmouk camp in Damascus on Sunday, killing at least 25 people sheltering in a mosque in an area where Syrian rebels have been trying to advance on the capital, opposition activists said.
They said the deaths resulted from a rocket hitting a mosque in the camp, to which refugees have fled from other fighting in nearby suburbs of Damascus. It was the first reported aerial attack on the camp since the revolt against President Bashar al-Assad erupted last year.
Yarmouk, in southern Damascus, is part of an arc sweeping from the east to southwest of the Syrian capital where Assad's forces have been trying for several weeks to push back rebels from the gates of his power base.
A video posted on Youtube shows bodies and body parts scattered on the stairs of what appears to be the mosque.
Syria is the home of more that 500,000 Palestinian refugees, most of them living in Yarmouk. Assad's government and Syrian rebels have enlisted and armed Palestinians refugees during the 21-month uprising, which has escalated into a civil war.
Heavy fighting broke out 12 days ago between Palestinians loyal to Assad and Syrian rebels, together with a brigade of Palestinian fighters known as Liwaa al-Asifah (Storm Brigade).
The fighting intensified on Saturday with rebels gaining ground inside the camp, forcing Ahmed Jibril, a veteran leader of a Damascus-based Palestinian faction that back Assad to leave the capital with his son.
Jibril's PFLP-GC has maintained strong ties to Assad throughout the uprising, unlike the militant Islamist Hamas movement whose Damascus-based officials - including leader-in-exile Khaled Meshaal - quietly pulled out of Syria as the mainly Sunni Muslim revolt against Assad gained momentum.
