Duhok , Iraqi Kurdistan ( CNN ) In the canvas expanse of the Shariya refugee camp , thousands of Yazidis live within hearing distance of one of Iraqi Kurdistan 's frontlines with ISIS . The vast majority of the camp 's occupants are from the town of Sinjar and fled the ISIS assault there back in August . But not everyone escaped . ISIS took thousands of Yazidis captive . Men faced a choice -- convert to Islam or be shot . But the Islamist militants separated the young women and girls to be sold as sex slaves . In its fourth edition of `` Dabiq , '' the ISIS online magazine , an article titled `` The revival of slavery before the hour , '' outlines the group 's twisted justification and guidelines for the enslavement of the Yazidis . `` One should remember that enslaving the families of the kuffar ( infidels ) and taking their women as concubines is a firmly established aspect of Shariah , '' the article reads . We 're told that women who have just given birth or are breastfeeding are considered impure and can not be taken as sexual slaves -- but Hanan , 19 , was neither of those things . `` They separated all of us , '' she says . `` They dragged us away by our hair . They took married women , young ones . The youngest with us was just 10 . We were all crying . `` They said we are going to marry you off , you will forget your family . '' ISIS : Enslaving , having sex with 'unbelieving ' women , girls is OK. For the first week , Hanan was held with 50 others , regularly beaten and threatened with torture , and fed just a bowl of rice . The group was then taken to a three story building in Mosul she described as a sex slave warehouse , where hundreds of girls and women were held . `` They would line about 50 of us up at a time , in rows of 10 . They would say do n't move , do n't cry or we will beat you . The men would come in and describe the kind of girl they wanted and then they would pick and choose as they pleased , '' she recalls . She was eventually chosen , part of a group of 25 . From that group Hanan was separated into a smaller group of seven and taken into a house in a village . 'Treated like cattle ' : Yazidi women sold , raped , enslaved by ISIS . Two ISIS fighters guarded the door and ordered the girls to clean and bathe themselves . `` They brought in a Yazidi girl who had been with them for two months . She was wearing the black niqab . They said to us we are going to do to you what we did to her , '' Hanan says . `` The girl spoke to us in Kurdish and said they beat me , they cuffed me and raped me . '' Hanan and the others decided they had to try to escape . That night they crawled out the bedroom window . `` The fourth girl jumped out , I was the fifth . I crawled to the wall and was about to jump over it and then I saw their flashlight , '' she tells me . `` They caught the last two girls . '' They ran , and somehow evaded capture . Four hours later they were out of ISIS territory . `` If I just see someone with a beard I start shaking , '' Hanan says . Now physically free but mentally still captive , Hanan remains tormented -- like so many others , by what she has been through and what those still with ISIS are being forced to endure -- a fate worse than death . Fleeing ISIS -- A Yazidi family 's tale .
Hanan , 19 , was captured by ISIS when militants took the town of Sinjar . He is now being held in a prison near Mosul and has been charged with treason for his role as a Yazidi fighter against ISIS.
