MOSCOW (Sputnik) — According to the British broadcaster, the girls are being used to intimidate other people and carry out killings.
"They were Christian men. They [the Boko Haram fighters] forced the Christians to lie down. Then the girls cut their throats," a girl held captive by the militants told the BBC about the Chibok girls.
The Boko Haram extremist group began large-scale attacks in northeastern Nigeria in 2009, with the aim of establishing an Islamic state ruled by Sharia law. In February, the group expanded its attacks to neighboring Niger, Cameroon and Chad.
