Aden: Suspected Al Qaida militants killed five Yemeni soldiers in two separate attacks on 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, one source told AFP.

Almost at the same time two other soldiers were killed in nearby Azzan village when Al Qaida 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 Qaida suspects were also killed in an exchange of fire with soldiers at the Qatan army barracks in restive Hadramaut 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 Qaida for the drive-by shooting.

Al Qaida in the Arabian Peninsula 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.
