Teenager reveals how she tore off suicide vest given by Boko Haram and ran away

Strapped with a booby-trapped vest and sent by the extremist Boko Haram group to kill as many people as possible, the young teenage girl tore off the explosives and fled as soon as she was out of sight of her handlers.

Her two companions, however, completed their grisly mission and walked into a crowd of hundreds at Dikwa refugee camp in north-east Nigeria and blew themselves up, killing 58 people.
