The United Nations said today that more than 200 mass graves containing the remains of thousands of victims were discovered in areas controlled by the terrorist organization "Da'ash" in Iraq.

This came in a report issued by the United Nations in Geneva, and highlighted the legacy of the campaign of terrorism and violence launched by the organization "Daash" and calls for victims to uncover the truth and justice.

UNAMI and the United Nations Human Rights Office have documented 202 mass graves in Nineveh, Kirkuk, Salahuddin and Anbar provinces in northern and western parts of Iraq, but there may be much more.

According to the report, it is difficult to determine the total number of people buried in these tombs, but the smallest site in western Mosul has eight bodies, while the largest is believed to be the al-Khusafa gap site south of Mosul, which could include thousands.

The report stresses that these sites can contain sensitive criminal material to help identify victims' identities and to gain an understanding of the extent of crimes committed.

The evidence collected from these sites will be central to ensuring credible investigations, prosecutions and convictions in accordance with international standards of due process.
