In scenes eerily similar to the Chibok kidnapping of more than 200 girls four years ago, a convoy of fighters descended on a village in Yobe state late yesterday.
According to the residents, who spoke on condition of anonymity, the terrorists carted away food items from the stores of the Government Girls College, Dapchi, and petrol from hawkers, who abandoned their products to run for safety.
A teacher at the school told Daily Trust that 94 students could not be accounted for following a roll call.
Reports say the girls and teachers of the Government Girls Secondary School (GGSS) in the town managed to escape unhurt in the attack.
The Commissioner of Police, Yobe State command, Abdulmaliki Sunmonu, confirmed the attack.
However, some parents say more than 51 girls are still missing.
"They came to ask some of us that could not flee if there are soldiers in the village and we told them "no". We saw some people pushing some of the students to enter their vehicles.
Fifty-seven of them escaped, with 219 taken away.
The security services are said to be combing the surrounding area to find the missing girls.
The News Agency of Nigeria said it gathered from Dapchi residents that there was no casualty recorded and no injury sustained as the terrorists sporadically shot in the air to scare people away when they arrived in the town.
But a teacher at the school told the BBC the militants were only interested in looting, and left with food some three hours later.
Suicide bombings have continued despite repeated assertions by the government and the military since 2016 that is has defeated the Boko Haram insurgency, which aims to create an Islamic state in Nigeria's northeast.
The Chibok girls represent a fraction of the women captured by the militant group, which has kidnapped thousands during its eight-year insurgency in northern Nigeria.
