The girl, in an interview with the Kurdish News channel, said women and girls were suffering from extensive abuse by ISIL Takfiris.
She said as a common practice, the ISIL terrorists singled out three captive women and girls each time to be raped by the ISIL Emir (commander) and then passed them round among other militants.
The victims are then taken to the market to be sold as sex slaves and another three women are chosen to experience the same fate, she added.
The girl went on saying that the militants were free to rape or sell the captive girls as sex slaves to other members of the gang.
The Iraqi female captives were sold for $800-1,000 and the Yazidi ones for $500, she said.
The girl who has witnessed numerous atrocities by ISIL terrorists underscored that the militants killed Izadi men and boys at the sight of captive women and girls.
The girls recalls how militants separated young women and girls from the rest of the captives.
150 women captives were trafficked from their village in the northeast Iraq region of Sinjar to the northern Iraqi city of Tal Afar in Nineveh Province and were sexually abused by militants en route, she added.
The ISIL Takfiri terrorist group recently has abducted around 300 girls and women from the Izadi ethnic minority, keeping them as spoils of war or selling them off as sex slaves.
