They have described being tortured and forced to watch videos of men from their community being beheaded.Some, they said, were so traumatised by their experiences that they tried to commit suicide. However, those that tried to kill themselves were severely beaten by Isis fighters.Yazidi teenager Sara, 15, said that she considered suicide many times after she was kidnapped by Isis.Her horrifying ordeal began in the Sinjar village of Tal Azir on August 3 when Isis fighters advanced towards them.Along with her mother, her brother and his pregnant wife, they fled towards the mountains, but Isis caught up with them at a remote farmhouse.The women were separated from the men – who were simply mown down by machine gun fire in one of the rooms.Sara was bundled onto a pick-up truck and taken to Mosul, where she was held with hundreds of others prior to being sold off.She told Globalpost.com: 'We would try to make ourselves look ugly. Some women would cry or scream or fight, but it made no difference. They were always taken anyway. One girl hung herself. Another tried, but the IS guards stopped her and beat her very badly. No one else tried after that.'Sara, who described Isis fighters as 'dirty, with hairy faces and smelling bad' was eventually sold to 'an old man and a fat man'.She said that they would show her videos of Isis militants beheading her neighbors.She added: 'In some [videos] they put the heads into cooking pots. Sometimes they would stand on them. There were so many heads. And they would ask us, 'Do you know this one?' and laugh.'Sara, whose real name has been changed, recalled that she would sometimes have huge amounts of blood drawn from her arm by one of the men using a syringe, leaving her feeling sick and faint.Nineteen-year-old Leila's story is similarly disturbing. She described how her husband was shot dead by Isis, along with others from her village including boys of just 14, after trying to flee from her village in Sinjar.She was forced into the back of a pick-up truck and taken away, eventually driven to Mosul, like Sara.She said: 'We drove past so many bodies. Even the bodies of children.'Both girls eventually managed to escape, Leila before she was sold off, while militants slept, and Sara when her 'owners' were at Friday prayers.Kind-hearted locals risked their lives to help them get back to their relatives. Sara is now with family members in Erbil and Leila lives in Duhok.(dailymail.co.uk)Bakudaily.Az
