FILE - In this Sunday, May 5, 2013 file photo provided by the Syrian official news agency SANA, workers clear the rubble of buildings destroyed by an Israeli airstrike in Damascus, Syria. The attack targeted a shipment of highly accurate, Iranian-made guided missiles believed to be on their way to Lebanon's Hezbollah militant group, officials and activists said. The Syrian regime has enlisted a Damascus-based Palestinian militant group to threaten retaliation for the airstrikes. The relatively muted response to Israel's breach of Syrian sovereignty highlights President Bashar Assad's limited options as his regime battles for survival. (AP Photo/SANA, File)
