Iraq must do more to ensure that thousands of women and girls who survived sexual violence by "Islamic State of Iraq and Syria" (ISIS) elements receive care, protection and justice, the UN said Tuesday (August 22nd).

In a fresh report, the UN Assistance Mission to Iraq (UNAMI) and the UN rights office also warned that the children born as a result of the sexual violence risked facing a lifetime of discrimination and abuse, AFP reported.

"The physical, mental and emotional injuries inflicted by ISIS are almost beyond comprehension," UN rights chief Zeid Raad Al Hussein said in a statement.

"If victims are to rebuild their lives, and indeed those of their children, they need justice and they need redress," he said.

Tuesday's report pointed to the horrific abuse suffered by women and girls, especially from the Yazidi minority, in ISIS-controlled areas, including rape, abduction, slavery and cruel, inhumane and degrading treatment.

It also warned that women who were married to ISIS fighters, with or without their consent, risked "discrimination and forms of collective punishment" based on the suspicion they co-operated with the group.

The report raised particular concerns over the situation of hundreds of children born to women in ISIS-controlled areas without birth certificates or with ISIS-issued documents not accepted by Baghdad.

"The government must ensure (these children) are protected from marginalisation and abuse," the UN rights chief said.

He urged Baghdad to ensure that these children are "neither exposed to discrimination through references on their birth certificate that they were born out of wedlock or have a father linked to ISIS, nor left unregistered and at risk of statelessness, exploitation and trafficking".
