A government official said on condition of anonymity that six people were killed on

Thursday in three explosions that targeted a Yemeni government army compound in

the south-eastern city of Mukalla.

He said in Sana'a that the back-to-back blasts injured at least 10 people, and the casualties included civilians.

He said one explosion was carried out by a suicide car bombing.

The attack came weeks after forces loyal to Saudi-backed Yemeni President Abd Rabu Mansour Hadi retook control of Mukalla from al-Qaeda insurgents.
