Is there no end to the horror for people living under Islamic State rule? Beheadings, beatings, mutilation and sexual slavery is rife.

A New York Times report has revealed that ISIS militants are forcing their female captives to use birth control so they can keep raping them.

It's a way of getting around ancient Islamic law as practiced by the militants, which states that unmarried women being kept captive must not be pregnant when they're raped.

To keep the sex trade running, young women—mainly captives from the Yazidi minority group—are made to use contraception which allows them to be bought and sold between Islamic State fighters.

Journalist Rukmini Callimachi travelled to Iraq for the New York Times to expose this story. Rukmini Callimachi joins Fran Kelly on RN Breakfast.
