Video - Nigeria's Chibok schoolgirls: Five years on, 112 still missing

It has been five years since hundreds of schoolgirls were abducted in north-eastern Nigeria by Boko Haram fighters. While a total of 164 girls have been found or released as part of a deal between the Nigerian government and the armed group, 112 are still missing. In Nigeria's capital, there are renewed calls for the search to continue. The international outcry sparked the Bring Back Our Girls movement, which continues to this day. Despite the pain, one mother still hopes she will once again see her daughter alive.
