Officials in Yemen have reported that an attack on the Defense Ministry compound in Sanaa was a suicide car bomb. It's reported that 52 people have died, with a total of about 20 injuries. Yemen's al-Qaida branch has taken responsibility for the attack.
The Associated Press reports a car full of gunmen dressed in Yemeni army uniforms arrived at the scene immediately after the blast and engaged in a gunfight with troops in an apparent attempt to take over the complex. It's reported that 12 gunmen were killed.
The explosion was very violent, the whole place shook because of it and plumes of smoke rose from the building.
