A schoolgirl, who was among 200 kidnapped in Nigeria by militant group Boko Haram, has been found with a 10-month-old son.

The Nigerian army says she was discovered in Borno State by troops who were screening escapees from the group's base.

The girls were taken from a class in Chibok two years ago.

Last month, the Islamist militant group released 21 of the schoolgirls into the custody of the Nigerian government.

The girls have been reunited with their families.

They were released reportedly as part of a prisoner swap deal. This claim has been rejected by Nigerian authorities.

The group had previously said that the girls would not be released until the government released Boko Haram prisoners.

It followed negotiations between Boko Haram, the International Red Cross as well as the Swiss and Nigerian governments.

The kidnapping led to international condemnation, with US First Lady Michelle Obama among those joining a campaign with the hashtag: #BringBackOurGirls.

Boko Haram has been driven out of most of its bases in northern Nigeria but in the past year, it has moved across the border to Chad.
