The UN says more than 200 mass graves have been uncovered in Iraq, in areas previously controlled by the Islamic State.
The graves are yet to be properly excavated, due to booby traps but are thought to hold between six thousand to twelve thousand bodies.
Suki Nagra, the director of the UN’s Human Rights office in Iraq, said the sites need to be protected and treated as crime scenes until they can be dug up by properly trained forensic experts.
