The military has revealed that six people were killed on Friday when a suicide bomber blew himself up at a mosque in Damboa. Army spokesman Colonel Sani Usman said the attack happened at about 5:15 am (0415 GMT) in the town of Damboa, Borno state.
He blamed the attack on "two Boko Haram terrorists".
"The first suicide bomber targeted Damboa Central Mosque but due to stringent security measures he could not gain entry. Obviously frustrated, he exploded and died near the central mosque," he added.
"However, the second bomber veered off and gained entry into another smaller mosque and detonated the bomb, killing himself and six other worshippers and injuring one other person.
"The wounded have been evacuated to a hospital while efforts are on to clear the rubble. Troops and other security agencies have been mobilised to the area."
Usman said suspected Boko Haram fighters also attacked the village of Gaskeri, near the sprawling internally displaced people’s camp at Dalori, outside Maiduguri, on Thursday night.
"They killed three civilian vigilantes and looted foodstuffs. Troops have been mobilised and they are on the suspected terrorists’ trail," he added.
