Two senior Yemeni security officers were killed in separate attacks in the southeastern province of Hadramout early Sunday, a government official told Xinhua.

"Attackers suspected of belonging to the Al Qaeda terrorist group killed a senior security officer by gunfire and an intelligence officer in an ambush in different areas in Hadramout province," the government official said on condition of anonymity.

The senior security officer was traveling in his own car when he came under a hail of bullets in the northwest of Hadramout and the intelligence officer was ambushed by "terrorists" in Ghail Bawazir region, he said.

On Friday, an Al Qaeda suicide car bomber stormed a military base in Yemen's southern province of Abyan, killing at least 15 soldiers and injuring dozens of others.

Yemeni security services have repeatedly blamed militants of the Yemen-based Al Qaeda offshoot for a series of assassination attacks, mostly in the country's southern regions.

The Yemen-based Al Qaeda in the Arabian Peninsula, which emerged in January 2009, is considered the most strategic threat to the Yemeni government and neighboring oil-rich Saudi Arabia.
