SANAA, Yemen -- Yemeni officials say that militants have shot down an army helicopter, killing all eight people on board including a military commander.
The officials say the helicopter was downed by a missile over the al-Qaida stronghold of Wadi Ubida in central Yemen. The helicopter was flying from the capital Sanaa to the province of Marib, officials said. The passengers were part of a military force guarding oil installations in the province.
The officials spoke on condition of anonymity because they were not authorized to speak to the press.
The attack comes at a time the U.S. and British embassies evacuated staff amid reports of a threatened attack by the terrorist group.
