JEDDAH, Saudi Arabia (AP) — The head of the Syrian moderate opposition is asking for more foreign aid as his rebels try to beat back a bloody insurgency even as they continue their so-far unsuccessful effort to oust Syrian President Bashar Assad.

Syrian opposition leader Ahmad al-Jarba’s plea Friday comes as the White House seeks to send $500 million to the increasingly beleaguered moderate Sunni rebels who are facing two fronts in the protracted civil war.
