Twin blasts have killed at least 22 people in a mosque in northeastern Nigeria. Two female suicide bombers detonated explosives in Maiduguri, capital of the restive Borno state, which is at the epicentre of an insurgency led by Boko Haram terrorists.

One suicide bomber blew herself up in the mosque and the other outside the building, killing worshippers who were trying to flee. A statement by Colonel Sani Kukasheka Usman, seen by IBTimes UK, said at least 18 people were injured in the attack.

"Troops, security agents and care givers have been mobilized to the scene, while the wounded have been evacuated to Molai General Hospital for treatment," the statement read.

No group has claimed responsibility for the blasts, but the focus is likely to rest on Boko Haram, renowned for kidnapping civilians and forcing them to carry out suicide bombing missions.

"While we commiserate with the families of the victims of this dastardly act, we wish to reassure the public that we would continue to rout the remnants of the Boko Haram terrorists wherever they may be hiding. Meanwhile, we implore members of the public to be more security conscious, cooperate with the troops and security agencies," continued Usman.
