An ISIS sex slave 'receipt' has emerged from the newly liberated Iraqi city of Mosul showing how women were being traded by warped fanatics.

The 'bill of sale' reveals how one woman, described as '20-years-old, physically fit with brown eyes', was given a price of $1,500 (£1,145).

The hand-written note, signed with fingerprints, appears to show she was sold by someone called Abu Zubair to an individual named as Abu Monem.

While the document has been circulated on social media, its authenticity has not been independently verified and the identity of the woman involved is not known.

Many sex slaves captured and traded by ISIS are from the Yazidi community.

ISIS regards Yazidis, who are neither Arab nor Muslim, as being devil-worshippers and have committed terrible atrocities against the minority in Iraq, murdering thousands and taking women and children as sex slaves.

Last year details emerged of an ISIS posting in Arabic of a girl for sale saying:'Virgin. Beautiful. 12 years old.... Her price has reached $12,500 and she will be sold soon.'

The advertisement, along with others for kittens, tactical gear and weapons, appeared on an encrypted Telegram app and was shared with The Associated Press by an activist with Iraq's persecuted Yazidi community.

Last month an Iraqi politician claimed that one Yazidi sex slave unwittingly ate her one-year-old son after ISIS fanatics cooked the child and served it with rice after starving her for three days.

The starving woman had been kept captive in a cellar for days without food or water before she was tricked by her evil guards, according to MP Vian Dakhill.

When ISIS swept across northern Iraq almost three years ago, it carried out mass killings that the United Nations said qualified as genocide.

Most of the several hundred thousand members of the Yazidi minority live in northern Iraq, mainly around Sinjar, a large town which anti-ISIS forces have now retaken but was largely destroyed.

In 2014, ISIS jihadists captured Yazidi women and turned them into sex slaves to be sold and exchanged across their self-proclaimed 'caliphate'.

Around 3,000 of them are believed to remain in captivity. A number of mass Yazidi graves were uncovered in 2015.
