A Yazidi teenager has told how Islamic State fighters stormed her town with shocking brutality, dragging girls as young as ten  by their hair and carting them off like cattle to become sex slaves. Hanan, 19, was snatched from her family, suffered regular beatings and taken to a warehouse in Mosul, Iraq, where hundreds of women were lined up and hand picked by jihadist militants. She and six others were then taken to a house in a nearby village where they met a fellow Yazidi girl who had been incarcerated there for the last two months, she told CNN's Arwa Damon. The girl told them she had been beaten, handcuffed and raped and their captors warned they would soon suffer the same fate. Scroll down for video . Newly released members of the Yazidi minority, including one girl with an injured leg, wait for medical help after being set free by ISIS near Kirkuk, northern Iraq last week. One Yazidi survivor (not pictured) has told how girls as young as ten were dragged away from their families and raped at the hands of ISIS militants . Hanan managed to escape that night with some of the other girls by jumping out of a bedroom window, but two of them were caught as they fled. Speaking of the moment ISIS attacked her village last August, she said: 'They separated all of us. They dragged us away by our hair. '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.' Hanan is now recovering at the Shariya refugee camp in Dohuk Iraqi Kurdistan, where hundreds of other Yazidis have fled, but says she shakes with fear every time she sees 'someone with a beard'. Tens of thousands of Yazidis were forced to flee for their lives - many of them into the nearby Sinjar mountains and then into Kurdish-held regions of northern Iraq during the ISIS offensive in August. Relief: 216 prisoners, including 40 children, believed they were being led to their execution, but were instead piled onto minibuses for a handover southwest of Kirkuk. It is not known why they were released . However many were captured by the militants, resulting in the massacre of hundreds of men and the selling into slavery of women and children, after they were first divided up between militants . A magazine published by the terror group, Dabiq, last year attempted to justify the sickening treatment of the Yazidis. Explaining why Yazidis have been sold into sex slavery while those from other groups have not, the magazine claims Islamic Sharia law allows the enslavement of innocent 'polytheists and pagans' but not of those the militants regard as simply heretical. Last week, aid workers reported that a nine-year-old girl was pregnant after suffering horrific sexual abuse at the hands of ISIS militants in northern Iraq. She was among more than 200 Yazidi women, children and elderly who were released near Kirkuk, northern Iraq after being taken hostage last June. According to aid workers, she was 'sexually abused by no fewer than ten men', while in captivity inside the self-proclaimed caliphate.
