At least 10 people are believed to have died after a female suicide bomber attacked a college in Kontagora, in Nigeria's central Niger State.
Niger state police spokesman Ibrahim Gambari confirmed the blast at the Federal College of Education.
"At least 10 students were killed and several others injured. They have all been moved to the general hospital. We have all been asked to vacate the school," a witness told AFP
The woman detonated the device as she tried to enter the college's library, witnesses told Reuters.
Although no one has yet claimed responsibility for the attack, it is believed that it might have been carried out by members of the Boko Haram terror group.
The militants earned global attention after they kidnapped some 220 girls in Chibok, Borno State, last April.
Weeks after the mass abduction, reports alleged that the girls were being used by the militants to carry out suicide attacks.
