Shireen Mato, now a Wagga resident, used to live in the village before ISIS surrounded the town in 2014. After 13 days, ISIS gathered people in a community hall.

"First they collected and kept all of the belongings and separated women from men," Ms Mato said. "Then took men and teenagers outside of school and shot them in 12 different locations.

"My sister was in ISIS captivity for about one year .. she was tortured physically and psychologically."

Ms Mato's sister was sold for less than $100 to four men as a sex slave.

A friend of her's refused to marry an ISIS soldier, so her husband was killed. They gave her food for the children, but Ms Mato said when her friend awoke she discovered they had been fed poisoned food and her children had died.

She added that one month would not be sufficient enough time to tell all of the atrocities the Yazidi people faced.
