Suspected Al-Qaeda militants killed five Yemeni soldiers in two separate attacks Sunday, including a suicide car bombing, in the second day of deadly operations against the military, army sources said.

Three soldiers were killed in one attack when a suicide bomber rammed his vehicle against an army position in the southern Shabwa province town of Maifaa.

Almost at the same time two other soldiers were killed in nearby Azzan village when Al-Qaeda suspects opened fire with automatic weapons at another military post, another army source said.

Witnesses said clashes erupted between the gunmen and soldiers after the Azzan attack.

Early Saturday a double attack, also including a suicide car bombing, targeted troops in southeast Yemen, leaving four soldiers dead. Ten Al-Qaeda suspects were also killed in an exchange of fire with soldiers at the Qatan army barracks in restive Hadramawt province.

Also on Saturday a police officer was killed outside his home by gunmen who fired from a motorbike, with a local official blaming Al-Qaeda for the drive-by shooting.

Al-Qaeda in the Arabian Peninsula, considered by Washington as the most dangerous affiliate of the extremist network, is active across several parts of Yemen, taking advantage of a collapse of central authority during a 2011 uprising that ousted veteran president Ali Abdullah Saleh.
