Kano, Nigeria (CNN) – At least 47 people were killed and 79 were wounded Monday by a suicide bombing outside a school in northern Nigeria, police said.
The attacker was disguised as a student when he set off the explosion in a government boarding school in the town of Potiskum, police spokesman Emanuel Ojukwu said.
“We suspect Boko Haram is behind the attack,” Ojukwu said.
The explosion took place at 7:50 a.m. local time outside the principal’s office, where students had gathered for a daily speech.
“We were waiting for our teachers to come and address us at the assembly ground when we heard a huge explosion,” student Adamu Ibrahim said.
