FILE - In this undated file photo, Syrian Commander Riad al-Asaad, who heads a group of Syrian army defectors appears on a video posted on the group's Facebook page. The Britain-based Syrian Observatory for Human Rights said Monday March 25, 2013 a bomb stuck to his car targeted Col. Riad al-Asaad during a visit to the town of Mayadeen in eastern Syria. The Observatory cited conflicting reports on al-Asaad's fate, with some saying he had been killed and others saying he lost a leg. There was no immediate claim of responsibility for the attack.
