Foreign fighters in Yarmuk

"Foreign nationals fighting in Syria are using a Palestinian refugee camp in Damascus as a base to fight the Syrian government, a Palestinian official said Saturday.  "We're calling committees in the camp and people there told us that foreigners are shooting at anyone that moves and they're using the camp and the people of the camp as shields to attack government forces," Bassam Abu Sharif, a former adviser to late leader Yasser Arafat, told Ma'an."
