A gunman opened fire today outside a school in northeast Nigeria's city of Potiskum, seriously wounding 12 students in an area repeatedly targeted by Boko Haram, a police officer and witnesses said.
"We have evacuated 12 people with serious gunshot wounds to hospital from the scene of the shooting attack," said the officer, who requested anonymity
Multiple students at the College of Administrative and Business Studies in Potiskum, Yobe state, said the attacker with explosives strapped to his body blew himself up when he ran out of ammunition, but the blast caused no other casualties.
