On the night of 14–15 April 2014, 276 mostly Christian, with some Muslim, schoolgirls aged from 16 to 18 were kidnapped by the Nigerian militant group Boko Haram from the Government Girls Secondary School in the town of Chibok in Borno State, Nigeria. Prior to the raid, the school had been closed for four weeks due to deteriorating security conditions, but the girls were in attendance to take final exams in physics.
