Al-Qaida militants killed seven soldiers Tuesday in two suicide car bomb attacks at a military encampment in the southern Yemeni city of Sayoun, military officials said.

The attacks, which also wounded eight soldiers, started with a suicide car bomb attack on the camp gates while a second suicide car bomber detonated his explosives inside the camp's grounds, officials said. The officials spoke on condition of anonymity because they were not authorized to brief journalists.

The official Twitter account of Yemen's al-Qaida branch claimed responsibility for the attacks, saying they killed and wounded dozens of soldiers.

Sayoun, the biggest city in Hadramawt province, witnessed fierce fighting last summer between the army and al-Qaida. Washington views Yemen's al-Qaida branch as the most active and dangerous affiliate of the terror network.
