A powerful explosion went off in Damascus' historic Marjeh Square Tuesday morning, killing and wounding dozens. Government media put the casualty figures at 13 dead and over 70 wounded.
Ambulances and rescue workers evacuated the dead and wounded from Damascus' iconic Marjeh Square. Windows were blown out from nearby buildings, palm trees caught fire, and crumpled vehicles were strewn about.
Amateur video showed a thick cloud of white smoke rising over the city center while residents of nearby districts reported being jolted by the blast. It was the second powerful explosion to rock the Syrian capital in 24 hours.
