According to the leader of the Civilian Joint Task Force (CJTF) in Ajiri Yala, some 15km north of Maiduguri, the attack happened at  4:30 a.m. (0330 GMT)..

“A male suicide bomber disguised as a worshipper entered the mosque while people were gathering for the morning prayers,” he told AFP by telephone.

“He detonated his explosives. He killed five people and injured several others.”

There has been no claim of responsibility so far, but such attacks are usually carried out by Boko Haram terrorists, which are active in northeastern Nigeria.

On Sunday, an explosion killed a CJTF member on guard at checkpoint in the Muna area of Maiduguri.

A week earlier, 14 people were killed in a similar blast near the Muna Garage camp, which is home to tens of thousands of people made homeless by Boko Haram militancy.
