A female suicide bomber injured four people on Wednesday at a teacher training college in northwest Nigeria, blowing herself up before she could reach her target, police said, AFP reports.
At least 10 people had been feared dead in the blast at the Federal College of Education in Kontagora, Niger state, according to a student at the scene.
But state police spokesman Ibrahim Gambari said later that only the bomber died and four others were injured — three students and a bystander.
“An unidentified suicide bomber blew herself up before she could reach her target, which was the school library where many students were reading for their exams,” he told AFP.
The blast came two days after nearly 60 people were killed in a suspected Boko Haram suicide bombing at a school in the town of Potiskum in northeast Yobe state.
Nigerians have come to expect near daily Boko Haram attacks in the far northeast but the latest attack will raise fresh concern if linked to the Islamist uprising.
Niger state has not been touched by the insurgency in more than two years and Kontagora is roughly 2,000 kilometres (1,200 miles) from Boko Haram’s northeastern stronghold.
On the Monday’s Yobe bombing, an official from the all-boys school in Potiskum, who requested anonymity, said the casualty toll had risen to 58 dead and 117 injured.
Police had previously put fatalities from the bombing at 47 and the wounded at 79.
