Islamic State theologians have issued an extremely detailed ruling on when "owners" of women enslaved by the extremist group can have sex with them, in an apparent bid to curb what they called violations in the treatment of captured females. The United Nations and human rights groups have accused the Islamic State of the systematic abduction and rape of thousands of women and girls as young as 12, especially members of the Yazidi minority in northern Iraq. In an April report, Human Rights Watch interviewed 20 female escapees who recounted how Islamic State fighters separated young women and girls from men and boys and older women. Fatwa No. 64, dated Jan. 29, 2015, and issued by Islamic State's Committee of Research and Fatwas, appears to codify sexual relations between IS fighters and their female captives for the first time, going further than a pamphlet issued by the group in 2014 on how to treat slaves.
