A suicide car bomber attacked a security intelligence post in southeastern Yemen on Saturday, wounding two military guards, an official said, blaming Al-Qaeda of responsibility.

The bomb-laden vehicle exploded at the entrance of the post in a residential neighbourhood of Mukalla, the provincial capital of Hadramawt, causing damage to it and other buildings, said the security official.

Guards had opened fire on the car driven by an "Al-Qaeda suicide bomber" as it approached the entrance, the official said, speaking on condition of anonymity.

The Yemen-based Al-Qaeda in the Arabian Peninsula is regarded by the United States as the global jihadist network's most dangerous franchise and has been subjected to an intensifying drone war this year.

On Friday, senior AQAP member Qassem al-Rimi threatened in an online video to strike back at any party involved in the drone campaign that has killed dozens of suspected jihadists.

The Yemeni army launched an offensive on Tuesday against hideouts of the Al-Qaeda affiliate, mainly in the south where the militants are strongly rooted.
