>> this is boko haram territory. they made themselves known to the world two years ago. kidnapping nearly 3 00 girls from their school in a nigerian town. >> i abducted your girls. i'll sell them in the market. >> it's a tragedy. it's a tragedy that young women are kidnapped. >> reporter: the mass abduction triggered global outrage and a campaign, "bring back our girls". >> this act was committed by a terrorist group determined to keep these girls from getting an education. >> reporter: though some managed to escape. >> they said if we run, or shout, they'll shoot all of us. >> reporter: most are still missing. and so are thousands of other women and children also kidnapped. which is why we're traveling with the u.s. ambassador to the

u.n. she's here to reto focus on the kidnapping. this is a home to people fleeing from the terror. not this teenager, she's asked us not to show her face. she fears for her life. >> how old were you when boko haram came? >> she says she was 14 when she was forced to marry a boko haram fighter. >> translator: sometimes when women flee the men they were married to, they catch them and slaughter them. >> tell me your reaction. >> what is there to say? i mean, you're a 14-year-old girl in your village. these guys show up and they say hey, i have a choice for you. i'm going to kill you or you can marry me. she feels that was a choice? that wasn't a choice. they didn't give her a choice.

it's left her with shame. all she carries with her at least that she conveyed was a sense that she made the wrong choice. >> reporter: even after being rescued and returned to their families, they face stigma from their communities. >> they destroy us and destroy life. >> when you talk to these kids, they have the same story. their families were drifren out of their villages often witnessing their parents be killed and then fleeing for days into the forest before arriving in a camp like this. >> reporter: we hear heart breaking stories of sexual slavery, forced majors, forced conversions. and senseless killings. >> translator: they showed a gun and said whoever holds the bible, we slaughter them, and whoever goes to church gets the same thing. >> reporter: this woman tells us how six fighters slit her father's throat and cut out his tongue before her eyes. children like these are not just

victims. they're now being used as weapons. boko haram turning kidnapped boys and girls into suicide bombers. often the reporting treats it like it's willingly strapping on the belt and reading the koran and deciding this is what they did. this is what consent looked like when you're 14. there's reports of 8-year-old suicide bombers and it's being treated as if they're willful. >> reporter: they are brainwashed into thinking it's a direct path to god or coerced or drugged or remotely detonated. of the 151 suicide attacks in the region last year, one in five were children and 75% of those bombers were girls. turning women and children once seen as innocent into potential threats. >> many don't know what they're carrying. >> reporter: the african generals waging this war have

pushed boko haram back, but at this security briefing belearned the terror group is using new tools and tactics from suicide belts to a new kind of ied. birds being used as bombs, and boko haram recently pledged allegiance to isis. >> they share procedures and you can see it by the way they conduct their attacks. >> reporter: u.s. troops are not fighting here, but they are advising and sharing intelligence in the search for the missing girls. >> lined up against a yellow wall, 15 girls. >> reporter: cnn recently obtain third down so-called proof of life video that purports to show some of the girls alive. though authorities are skeptical about the video, it's sparking renewed vigor. the wildly held theory is they're alive but separated living in a forest, a stronghold of boko haram. we'll hear more about that later. first, we're on our way to the

of the truck and die than to go with them, because if i died here, my parents might have my body and bury it. >> reporter: after a night hiding from boko haram in the forest, they finally make it back to your families. >> when i reach home my mom and family are crying. >> reporter: she says the one night traum tiegzed her so much it took a lot of convincing to get her to come to school here. >> boko haram said if we go to school anywhere and they find out, they'll kill us and our family. i was scared and i told her i'm not going to school anymore. i'm done with school. >> reporter: now both girls are studying in the u.s. looking to the future. but they miss the families they left behind. >> i was so worried about my family. i know that i'm safe here, i'm okay, but it's not safe for my family back there in nigeria. >> reporter: their loved ones are okay for now, and we were able to track down blessing eegs father when we were there. >> do you want to hear what he says?
