Boko Haram has kidnapped more than 100 schoolgirls from the town of Chibok in Borno State.
The government closed all schools in Borno three weeks ago because of frequent attacks in which hundreds of students have been killed in the past year. The girls who were kidnapped had been recalled so they could write their final exams.
The extremists have been using abducted students as cooks, sex slaves and porters.
Boko Haram has been on a rampage this week, blamed for four attacks in three days that started with an explosion at a busy bus station during the Monday morning rush hour in Abuja, the capital, which killed at least 75 people.
Two attacks in northeastern villages killed 20 people Tuesday night and Wednesday morning.
People from Chibok are searching the Sambisa Forest for them.
Education is forbidden, but mass murder and kidnapping for enslavement and rape – those are not forbidden. Funny kind of god Boko Haram has.
