At least five people were killed and dozens injured Tuesday when a military helicopter crashed into a building complex near historic “Change Square” in the Yemeni capital of Sana. The pilot and seven passengers were reportedly killed upon impact. Officials say the death toll will likely continue to rise as fire and black smoke pour from the site of the crash—a residential area with many shops. A witness reportedly saw two houses completely annihilated, leaving many trapped beneath rubble. Yemen has seen increased violence in 2013, and at least 10 al Qaeda militants killed by a drone strike in late January.
