Witnesses said Boko Haram insurgents perpetrated the attack at about 8a.m. when the students converged for the morning assembly session.
A witness, who spoke to journalists on phone, said:
“It is another bad day for us today, a bomb just went off at Senior Science Secondary school Potiskum….it happened at the assembly ground.
“Many bodies of students are presently on the ground in pools of blood… We are running home now.”
Potiskum Senior Science Secondary School is one of the densely populated boarding schools for boys located very close to Potiskum General Hospital in the heart of the town.
