The Coordinator, National Information Centre, Mr Mike Omeri, said that soldiers killed one of the suspected bombers of EMAB Plaza in Abuja and arrested another.
He said the attackers came on a power bike and planted an Improvised Explosive Device by the entrance of the shopping mall.
He also confirmed the death of 21 persons and 17 others injured in the blast which also damaged several vehicles.
NAN gathered that the suspects, who attempted to flee the scene of the incident, were shot and arrested by personnel of the Guards Brigade on patrol duty in the area.
One of them later died from wounds sustained from gunshots while a bag containing IEDs was also recovered from the suspects.
