Salamatu Umar was abducted by Boko Haram in 2014, when she was just 15. She and five other girls were herded in the bush. She was forced to marry a Boko Haram fighter.
She and another girl eventually escaped, running away while they were collecting firewood for cooking. Umar was pregnant at the time.
Today, she is 18 and the mother of a 1-year-old son, Usman Abubakar. She survived her "hell" and lives in a displaced people's camp in Maiduguri, the main city in northeastern Nigeria and birthplace of Boko Haram.
Umar is free — and yet she is not really free.
