The bomber was reportedly chasing a convoy carrying two police officers, but missed the target.
A civilian vehicle was caught in the explosion instead.
The dead included three members of the security forces, who were patrolling the area located near the presidential palace, and the bomber.
Six people were reported to have been injured.
Witness Abdisalan Garad said some of them were inside a nearby restaurant hit by the blast, while parts of the building collapsed.Promote Your Music On This Platform Contact : Mobile : +2348132090729 BBM:33428A0F Email : email@example.com Twitter : @ijebuloadedNG
