A UN fact-finding mission which was established by the UN Human Rights Council in March 2017, found that Myanmar's armed forces had taken actions that "undoubtedly amount to the gravest crimes under international law".
Speaking in Geneva on Monday, Marzuki Darusman, the chairman of the investigative mission said that his researchers had amassed a vast amount of primary information, based on 875 interviews with witnesses and victims, satellite imagery, and verified photos and videos.
He described Myanmar's military as having shown a "flagrant disregard for lives" and displayed "extreme levels of brutality".
"The Rohingya are in a continuing situation of severe systemic and institutionalised oppression from birth to death," Marzuki said.
The UN report said that military generals, including Commander-in-Chief Min Aung Hlaing, must face investigation and prosecution for genocide in north Rakhine State, as well as crimes against humanity and other war crimes in Kachin, Shan and Rakhine states.
