An unspecified number of teenage girls were abducted on Sunday in Bam Village, located about 170 km south of state-capital Maiduguri, after razing buildings and killing at least seven people, a security official told Xinhua news agency.
Witnesses said the gunmen shot indiscriminately at the villagers.
Ali Mallam Ali, a local chief in the village, said most residents were still asleep when the incident occurred.
"The attackers gathered all the women in the village and separated the teenage girls from the married ones before taking them away," he said.
Another resident said news of the abduction has jolted the state, especially because more than 217 school girls abducted last year in Chibok town of the state are still missing.
Nigerian President Muhammadu Buhari has vowed to bring back the missing girls, although there are fears that some of them might have been taken across borders or married off by their abductors.
