More bodies were expected to be recovered as rescuers were combing the area till Sunday afternoon, a college official said.

On the same day, police confirmed 11 deaths after gunmen raided a village in Kaduna state Saturday. Houses were reportedly torched in the attack on Zangang village.

On Wednesday and Thursday, at least 27 people were killed by Boko Haram insurgents in attacks on villagers in Borno State.

The killings echoed a threat by a man claiming to be the leader of Boko Haram, Abubakar Shekau, to launch more attacks in northern Nigeria until the sect installs and decrees strict sharia law in Africa's most populous nation.

Boko Haram has caused thousands of casualties in northern states since launching insurgency in 2009. In the escalation of conflicts between its fighters and the military, Nigerian President Goodluck Jonathan in May declared a state of emergency in the northern states of Adamawa, Borno and Yobe.
