Noor (not her real name) was sold into slavery after ISIS overran her village in the Iraqi province of Sinjar. The 22-year-old says the militant who picked her out raped her -- but not before trying to justify himself.
"He showed me a letter and said, 'This shows any captured women will become Muslim if 10 ISIS fighters rape her.' There was a flag of ISIS and a picture of Abu Bakr Al Baghdadi."
After abusing her, he passed her on to 11 of his friends, who also raped her.
In ISIS territory, Yazidi women can be bought and sold for money, bartered for weapons, even given as a gift; but this is not a simple commercial transaction -- ISIS has made rape and slavery part and parcel of its -- brutal -- theology.
