On the night of 14–15 April 2014, 276[1] female students were kidnapped from the Government Secondary School in the town of Chibok in Borno State, Nigeria. Responsibility for the kidnappings was claimed by Boko Haram, an Islamic Jihadist and terrorist organization based in northeast Nigeria.

On 17 October 2014, hopes were raised that the 219 remaining girls [clarification needed] might soon be released after the Nigerian army announced[2] a truce between Boko Haram and government forces. The announcement coincided with the six-month anniversary of the girls' capture and followed a month of negotiations mediated in Saudi Arabia by Chadian president, Idriss Déby.

The announcement was met with doubt as this was not the first time the Nigerian government had claimed a breakthrough in negotiations with the Islamic militant group – it had to backtrack[3] on a previous announcement in September after saying the girls had been released and were being held in military barracks.
