Suspected Boko Haram gunmen raided the town of Buni Yadi after sundown on Monday, attacking the same area where scores of students were massacred in February.
They shot at soldiers manning a checkpoint, razed a police station and torched the home of a local leader and public buildings before opening fire on a primary school.
“When they started attacking, people began to flee. There were casualties on the part of the security personnel but I don’t know how many,” said witness Kura Babagana.
