BREAKING NEWS: Boko Haram Releases 21 Chibok Girls
Twenty-one of the Chibok schoolgirls kidnapped by Boko Haram have been freed, a senior Nigerian government official has told the BBC.
It is thought that they are now with the security services in the north-eastern city of Maiduguri.
It is not yet clear how the girls were rescued.
The Islamist militant group kidnapped more than 250 students from a school in Chibok in April 2014 – an act that provoked international condemnation.
