Suspected Al-Qaeda militants seized army headquarters in Yemeni port city Mukalla on Monday, killing two soldiers as a suicide bomber rammed a car into the entrance, a military official said.
The militants, who were dressed in special forces uniforms and drew up in four military vehicles, stormed the seaside base taking many more soldiers hostage, the official said.
The commander of the army's second military region, General Muhsen Hasan, was in the building at the time of the attack, and is thought to have been captured, another military official said.
Army reinforcements have been deployed to the area and have engaged the militants, the official said, warning that militants would "pay a heavy price" for the spectacular attack.
