The Nigerian army says that one of the abducted Chibok schoolgirls has been found, along with her six-month-old baby.

She was discovered by soldiers investigating suspected members of Islamist militant group Boko Haram.

Nigeria's military said the young woman is undergoing medical checks.

A total of 276 schoolgirls were kidnapped by Boko Haram from the town of Chibok in April 2014. About 200 of them are still in captivity. More than 20 were released in October in a deal brokered by the International Red Cross. Others have escaped or been rescued.

Over Christmas, 21 of the young women freed under the October deal returned home for the first time. However, family members told the BBC that they were kept in a politician's house and barred from going to their family homes.
