A United Nations report published on Tuesday accused the Islamic State of acts of war crimes, crimes against humanity and possibly genocide.

“The violence suffered by civilians in Iraq remains staggering,” the report, compiled by UN Assistance Mission for Iraq (UNAMI) and the Office of the High Commissioner for Human Rights (OHCHR), said.

“The so-called ‘Islamic State of Iraq and the Levant’ (ISIL) continues to commit systematic and widespread violence and abuses of international human rights law and humanitarian law."

"These acts may, in some instances, amount to war crimes, crimes against humanity, and possibly genocide.”

The report examined the IS' enslavement of over 3500 people, mainly women and children from the Yazidi community in 2014.

“During the reporting period, ISIL killed and abducted scores of civilians, often in a targeted manner,” the report further noted.

“Victims include those perceived to be opposed to ISIL ideology and rule; persons affiliated with the Government, such as former Iraqi security forces (ISF), police officers, former public officials and electoral workers; professionals, such as doctors and lawyers; journalists; and tribal and religious leaders.”

"Others have been abducted or killed on the pretext of aiding or providing information to Government security forces. Many have been subjected to adjudication by ISIL self-appointed courts which, in addition to ordering the murder of countless people, have imposed grim punishments such as stoning and amputations.”

The report also documented allegations of violations by Iraqi security forces, associated forces and the Peshmerga.
