IS committing 'staggering' violations in Iraq

Islamic State insurgents in Iraq have carried out mass executions, abducted women and girls as sex slaves, and used children as fighters in systematic violations that may amount to war crimes, the United Nations said on Thursday.

In a report based on 500 interviews, it also said Iraqi government air strikes on the Sunni Muslim militants had caused "significant civilian deaths" by hitting villages, a school and hospitals in violation of international law.

At least 9,347 civilians had been killed and 17,386 wounded so far through September, well over half of them since the Islamic insurgents also known as ISIL and ISIS began seizing large parts of northern Iraq in early June, the report said.

Islamist forces have committed gross human rights violations and violence of an "increasing sectarian nature" against groups including Christians and Yazidis in a widening conflict that has forced 1.8 million Iraqis to flee their homes, according to the 29-page report by the U.N. Human Rights Office and the U.N. Assistance Mission for Iraq (UNAMI).

"These include attacks directly targeting civilians and civilian infrastructure, executions and other targeted killings of civilians, abductions, rape and other forms of sexual and physical violence perpetrated against women and children, forced recruitment of children, destruction or desecration of places of religious or cultural significance, wanton destruction and looting of property, and denial of fundamental freedoms."

In a single massacre on June 12, the report said, 1,500 Iraqi soldiers and security officers from the former Camp Speicher military base in Salahuddin were captured and killed by Islamic State fighters.
