Two female bombers managed to kill at least 22 worshippers and offered several injuries to 17 others fleeing when they attacked a mosque in Umarari on Wednesday, Nigerian rescue officials have stated.

The attack took place on the outskirts of the northeastern city of Maiduguri - the birthplace of the Boko Haram armed group.
According to coordinator, Abba Aji of the civilian self-defence Vigilante Group, one bomber blew up inside the mosque and the second outside as survivors tried to flee.
While there was no immediate claim of responsibility, blame will likely fall on the insurgents.
Boko Haram has increasingly used suicide and bomb attacks as Nigeria's military pushes the group out of territories they once controlled. Several bombers have exploded themselves in recent months at roadblocks into the city manned by the military and vigilantes.
