MAIDUGURI, Nigeria — Nigerian troops rescued one of the Chibok schoolgirls kidnapped by Boko Haram extremists more than two years ago in a pre-dawn raid Saturday on a forest hideout. She had a 10-month-old boy born to a Boko Haram fighter, said a statement from army spokesman Col. Sani Kukasheka Usman.

It was the first army rescue of a Chibok girl.

Last month, Nigeria's government secured the freedom of 21 of the Chibok schoolgirls in the first such release negotiated with Boko Haram.

Another girl escaped on her own in May.
