At least 47 students have been killed by a suicide bomber at a school assembly in the north-eastern Nigerian town of Potiskum, police have said.
The explosion at a boys’ science and technical school in the town is believed to have been caused by a suicide bomber dressed as a student.
Militant group Boko Haram is believed to be behind the blast, police said.
The group has targeted schools during a deadly five-year insurgency campaign to establish an Islamic state.
Tragic. Prayers for Nigeria.
