A suicide bomber killed at least nine people and injured around 12 others on Friday in an attack on a mosque in northeastern Nigerian Damboa during early morning prayers, a military source said.
No group has claimed responsibility for the attack in the town of Damboa, which is in Borno state, but it bore the hallmarks of Islamist militant group Boko Haram.
Army spokesman Sani Usman said there were two suicide bombers involved, one of whom failed to gain entry to the Damboa Central Mosque and detonated his load in the street outside, killing himself but causing no other casualties.
He said the second militant managed to get into a smaller mosque nearby and blew himself up there, killing six worshipers and wounding one other person.
Usman said the attack happened at about 5:15 am (0415 GMT) in the town of Damboa, some 90 kilometres (56 miles) southwest of the Borno state capital, Maiduguri.
He blamed the attack on “two Boko Haram terrorists”.
