A deadly explosion has occurred at the Federal College of Education, Kontagora, Niger State, the state police said.
The Niger State police spokesperson, Ibrahim Gambari, said an unidentified female suicide bomber struck at the school on Wednesday, killing herself and injuring three others.
Police bomb units have deployed to the scene, he said.
A witness said however that at least one person was killed. That could not be confirmed.
“She detonated her bomb vest between the auditorium and the college library. She might have been on her way to the library,” Aisha Kontagora, who lives in Kontangora, told PREMIUM TIMES.
Ms. Kontagora said so far only the suicide bomber and a young boy, believed to be an Almajiri, died in the attack.
Niger State lies next to Abuja, the Nigerian capital.
