The Nigerian army says it has recaptured the north-eastern town of Chibok, which was seized by Boko Haram militants on Thursday.

Boko Haram fighters kidnapped more than 200 schoolgirls from the village in April, sparking global outrage.

The group, which says it is fighting to create an Islamic state in Nigeria, has repeatedly targeted villages in Borno state in recent months.
