A Yemeni top security official has said that al-Qaeda was behind Tuesday's attack against policemen in the eastern province of Hadramout, official media sources reported on Thursday.

The attack was not a traffic accident, rather than a successful assassination killing two police chiefs and three of their guards, chief of the Political Security in the province Abdullah al-Julaiz'a said.

Doubtless, al-Qaeda carried out the attack because the organization is known for such attacks against security officials and facilities in the country, he confirmed.

The remarks come as the investigation into the attack which took place in the district of al-Abr while the policemen were back from a border crossing trip is continuing.

A security cordon has been imposed in the area after the perpetrators ran away towards Sayoon city on the way to the neighboring province of Shabwa.

On Tuesday noon, gunmen ambushed the two cars carrying police chief in the Hadramout Valley and Desert Major General Ali Salim al-Amri and chief of the branch of the Central Organization of the Political Security Gen Ahmed BaWazeer and three of their guards.

The five were killed and their bodies were burned when the cars collided with a truck in the ambush site after they came under a hail of bullets.
