A contentious draft law being considered in Iraq could open the door to girls as young as nine getting married and would require wives to submit to sex on their husband’s whim, provoking outrage from rights activists and many Iraqis who see it as a step backward for women’s rights.

The measure, aimed at creating different laws for Iraq’s majority Shiite population, could further fray the country’s divisions amid some of the worst bloodshed since the sectarian fighting that nearly ripped the country apart after the U.S.-led invasion. It also comes as more and more children under 18 get married in the country.

“That law represents a crime against humanity and childhood,” said prominent Iraqi human rights activist Hana Adwar. “Married underage girls are subjected to physical and psychological suffering.

Iraqi law now sets the legal age for marriage at 18 without parental approval. Girls as young as 15 can be married only with a guardian’s approval.
