A member of the Yazidi persecuted minority religion, 29-year-old Mahdya, recently escaped from Baghuz, the last holdout of the terrorist organization Islamic State (ISIS), and revealed horrifying tales of children being inhumanely treated by the Islamist group's members.

Mahdya, while talking to Daily Mail, said that her niece Marwa Khedr, was just 10-years-old when the jihadis swept into their village in the Sijar region of Iraw and rounded up all the families at gunpoint. According to her, all the men were buried alive in mass graves, while women and children were taken to a nearby town and were segregated by age and sold. The most prized were the ones between the ages of 10 and 20 and were taken by senior ISIS members.

Marwa's aunt said that the last she saw of Marwa was months later after the incident and she was pregnant. The whereabouts of the child is not known now.

A former teacher who runs safe houses for Yazidis escaping the caliphate, Ziad Avdal, said: "There are a lot of girls like her. It is not just terrible that she is pregnant – these young girls may have been raped by 100 men before they become pregnant."

Reports state that the 29-year-old Mahdya, who fled Baghuz with her two surviving daughters, was among the nearly 6,500 Yazidis kidnapped by ISIS members, and now almost half of them are missing.

Mahdya recounted a horrifying tale of frequently being sold, forced to marry multiple times, assaulted, threatened with having her daughters raped, and seeing them being regularly beaten with cables by jihadi brides.

"I don’t know how many times I was sold," she told the outlet. "One man only had me for three days, then sold me again. They also held me underground for two months. It was so dark I could not tell night and day."

She said that during her four-and-a-half year ordeal, she also saw a white Westerner who joined ISIS after spending years in prison. She said that the man held her for 10 days. "He was buying girls, washing them, dressing them in beautiful clothes and then selling them," Mahdya said. 

She was sold to a fighter who bought her for cleaning and cooking, however, after four months he decided that he was going to marry his slave. "He told me that if I disobeyed, then he would marry my eight-year-old daughter or sell her to another man," she said.

She ultimately fled the region and was forced to eat animal dropping and stick to stay alive. She recalled: "I never thought I would survive."
