Suspected ISWAP fighters abducted all students present in their classrooms during Monday's raid on Government Day Secondary School in Lassa, Askira-Uba Local Government Area of Borno State.
Police Public Relations Officer Nahum Kenneth Daso told Daily Trust the attackers arrived on motorcycles. They exploited the town's market day to slip in undetected before striking the school.
"It's Lassa market day, so they took advantage, infiltrated the market on motorcycles and went to Government Day Secondary School, Lassa," Daso explained. He added: "They shot and killed one teacher and took away all the students who were in their classrooms."
According to Daso, security forces engaged the gunmen during the raid. This confrontation, he noted, limited the scale of the abduction.
Local sources say the gunmen stormed the school around 9 a.m. They fired shots indiscriminately before heading to the examination hall where final-year students were sitting for National Examinations Council tests.
Several students and teachers were taken to an unknown location. Security personnel have begun combing nearby bushes to locate them.
This attack marks the second major abduction in Askira-Uba in recent weeks. Forty-two pupils of Mussa Primary and Junior Secondary School were taken 47 days ago from the same area.
Parents of those earlier abducted students remain deeply worried. As of Sunday, they said no contact had been made by abductors, fueling grave concerns about their children's safety.
