Around 7,000 women and children were forced into slavery when ISIS attacked Northern Iraq. Sarab and her family were travelling by truck when it was stopped by ISIS militants. "One of the ISIS men carried me off the truck", she said. A week later, she was taken across the border to a slave market in the ISIS stronghold of Raqqa. The first man who bought Sarab was a 56-year-old Iraqi. He raped her. When she was 13, Sarab alleges her captor took her to the home of an Australian man who lived in Raqqa. She knew him as Abu Omar, a man who is being held without charge in a prison in Syria. Another Yazidi survivor, who wants to be known only as "S", said she witnessed a different Australian – a woman — hold captive a 10-year-old Yazidi girl, who the Australian woman called "Huda". She alleges she saw the Australian woman from this house beat Huda and that her husband, an IS fighter, repeatedly raped the child. Sarab endured another three years in captivity and was freed by chance when a Kurdish militia group encountered her captor on the road. Meanwhile Abu Omar is calling for help from Australia to end his detention. "I'm an Australian citizen. What is our situation? If we are going to be tried, OK, let's be tried. [But] on what basis?"
