 Story highlights Girl is being evaluated medically after her discovery, army says 
 
 She is said to be among schoolgirls that Boko Haram militants abducted in Nigeria in 2014 
 
 (CNN) One of the Chibok schoolgirls kidnapped by Boko Haram in Nigeria in 2014 was found Saturday by the Nigerian army, the army said. Around 270 girls were kidnapped in April 2014 by the Islamist militant group, which has killed 15,000 people and displaced more than two million during a seven-year insurgency aimed at creating an Islamic caliphate in north-east Nigeria. Sani Usman said the girl, Maryam Ali Maiyanga, was discovered by troops who were screening escapees from Boko Haram’s base in the Sambisa forest on Saturday morning in Pulka, Gwoza Local Government Area, in Borno State. She was discovered carrying a 10-month-old son among a group that had escaped from a Boko Haram hideout in Sambisa Forest, the army said. Last month, 21 of the girls were released by Boko Haram following talks with the government brokered by the International Red Cross and the Swiss government. Boko Haram has kidnapped hundreds of men, women and children but the kidnapping of the Chibok girls brought worldwide attention to the group and widespread condemnation.
– One of the 276 women and girls kidnapped from a Nigerian boarding school by Boko Haram in 2014 was found by the Nigerian army Saturday, CNN reports. The girl, identified by Reuters as Maryam Ali Maiyanga, was carrying a 10-month-old baby, her son Ali. She was with a group of people who escaped a Boko Haram base in the Sambisa Forest. Maiyanga was number 198 on Bring Back Our Girls' list of Chibok schoolgirls kidnapped in April 2014. She was abducted with her twin sister, who is still missing. Of the 276 girls and women taken from the Chibok boarding school, 57 quickly escaped from Boko Haram. Another was found in May after escaping, and 21 were freed in October as part of a deal made by the Red Cross and the Swiss government. The Nigerian government says it's negotiating with Boko Haram to release 83 more of the schoolgirls. The rest, sources tell CNN, are either dead or don't want to leave Boko Haram. The terrorist group has been fighting for seven years to set up an Islamic state in Nigeria, the BBC reports. It's killed some 15,000 people and displaced more than 2 million during its insurgency.
