Since the start of Boko Haram's insurgency thousands of boys and girls have gone missing across north east Nigeria. The Islamist group use the kidnap of children as a strategy in their asymmetric war. Girls, as young as eight, are taken to be married off to fighters or deployed as sex slaves and, increasingly, used to commit suicide attacks.
Adama (18) spoke of her experience: 'We were detained in a school where children should feel safe and develop. I had also been to school and kept thinking about the carefree time I had there. Now it had become a place of fear and violence...so tragic.'
