Chibok schoolgirl freed in Nigeria seven years after abduction

One of the Nigerian schoolgirls kidnapped by Boko Haram militants more than seven years ago is free and has been reunited with her family. Nearly 300 schoolgirls, most aged between 12 and 17, were abducted by Boko Haram in April 2014 from Chibok in northeast Nigeria, sparking an international outcry and the #BringBackOurGirls campaign for their release.
