Notorious terror outfit Boko Haram is suspected behind the attacks. The college massacre is the latest violence in northeastern Nigeria's Islamic uprising.
Sunday's violence, which occurred despite the prevalence of an emergency covering three states of the country, has begun to raise doubts about the Nigerian government's claim of winning the war against the terrorists.
Authorities of the college where the gruesome incident took place alleged that there were no security forces in the institute even though it was promised that protection would be provided to the students.
The students were shot in their sleep and their classrooms were torched
Forty-two bodies were recovered and 18 injured students were sent to the hospital where two more died. Almost all those killed are Muslims, said sources.
Nigerian President Goodluck Jonathan condemned the attack. Boko Haram terrorists have killed over 1,700 people since 2010.
Last week, members of another terror outfit Al-Shaabab attacked an upscale shopping mall in Nairobi, the capital of Kenya, and killed several people, including foreigners.
