Yemen said on Sunday the suicide attack on a military convoy this morning in its business capital Aden bore the hallmarks of Al-Qaeda. The attack left 4 soldiers dead and 21 others injured.
An investigation is underway to identify the attacker and the group behind, a security source said.
An explosive-laden car was rammed into the military convoy near the air force base in Al-Mansoura district while on its way to Abyan, where the army has been fighting Islamists for months.
Lately, the army with support from tribes has regained several cities in Abyan which were taken over by Islamists who announced the province as an Islamic emirate amid the persistent unrest across the republic.
Many militants, soldiers and civilians have been killed in the battles and tens of thousands of families have been displaced.
