Kurdish officials have reported that ISIS fighters executed 19 women for refusing to take part in 'sexual Jihad' with its fighters in Mosul, Iraq. The terrorist organisation had captured hundreds of women belonging to the Yazidi community from Sinjar district in northern Iraq. Zainab Hawa Bangura, a social activist from Sierra Leone, who is also the Special Representative of the United Nations Secretary General on Sexual Violence in Conflict, said that 'girls get peddled like barrels of petrol' and one can be bought by six different men.

Zainab Bangura, as reported in Daily Mail, said, "The girls get peddled like barrels of petrol... One girl can be sold and bought by five or six different men. Sometimes these fighters sell the girls back to their families for thousands of dollars of ransom."

She further added that the best looking Yazidi virgins are sent to depraved slave auctions in Islamic State's adopted capital of Raqqa in Syria, where they are stripped naked and sold to the highest bidder.

"They have a machinery... They have a manual on how you treat these women. They have a marriage bureau which organizes all of these ‘marriages’ and the sale of women... They have a price list." she said, reports the Daily Mail.

Some of the sex slaves who somehow managed to escape from escaped Islamic State's clutches have revealed gruesome tales of violence and sexual abuse. Some were traded as human cargo and were raped five times a day.

"He raped me about five times a day... My sister was barely 14 when they raped her... I could hear her screaming but I couldn't do anything as I was tied up" said one of the slaves, about her horrific experiences with the perpetrators.
