"Myanmar's top military generals, including Commander-in-Chief Senior General Min Aung Hlaing, must be investigated and prosecuted for genocide in the north of Rakhine State, as well as for crimes against humanity and war crimes in Rakhine, Kachin and Shan States", the report said.
It also condemns the de facto head of government, Aung San Suu Kyi, for failing to use her power or moral authority to stem or prevent the unfolding events and meet her responsibility to protect the civilian population.
It raises the remarkable prospect that the Nobel Peace Prize victor could see her own generals put on trial for crimes against humanity.
"The crimes in Rakhine State, and the manner in which they were perpetrated, are similar in nature, gravity and scope to those that have allowed genocidal intent to be established in other contexts", the report said.
We will discuss options for bringing the report before the Security Council with other members once the Fact Finding Mission have made their final presentation to the Human Rights Council in September.
Global pressure on Myanmar has been growing as U.N. -mandated investigators are set to publish a report on the crisis on Monday and the United Nations Security Council will hold a briefing on Myanmar on Tuesday.
Meanwhile, Facebook, which has acknowledged its slow response to a torrent of anti-Rohingya hate speech spread on its site in Myanmar, said Monday that it is banning 20 Myanmar people and organizations from the site, including Gen. Min Aung Hlaing.
Facebook's action today comes a week after Reuters published an investigative report that found more than 1,000 posts, comments and images that attacked Rohingya and other Muslim users on the platform.
The mission, which was created by the UN Human Rights Council in March 2017, concluded in its report that "there is sufficient information to warrant the investigation and prosecution of senior officials in the Tatmadaw (Myanmar army) chain of command". Brig. Gen. Maung Maung, a military representative in Parliament, said the army doesn't have any comment on the United Nations report.

She then called her husband and the British embassy and traveled to join the rest of her Iranian family in Damavand. The temporary release was meant to allow her to see her family, particularly her daughter, the ambassador said .
Packer said Myanmar has at least $12 billion in exports annually, and that powerful people, including military generals, benefit financially from foreign investments.
One of those commanders, Lt. Gen. Aung Kyaw Zaw, has already been singled out for USA sanctions as punishment for the attacks on Rohingya.
Under the constitution, civilian authorities have little control over the military.
The report said the situation was a "catastrophe looming for decades", and an inevitable result of "severe, systemic and institutionalised oppression from birth to death".
The mission also said that to expect justice from a domestic investigation in Myanmar is "simply naive, there is no accountability and there is no impartiality". "The U.S. will continue to hold those responsible accountable".
As NPR's Colin Dwyer reported earlier this month, "The Trump administration's sanctions were quickly criticized for aiming at the middle tiers of Myanmar's security apparatus and leaving its highest rungs untouched". It said it was deleting 18 Facebook accounts, one Instagram account and 52 Facebook pages.
The company had already pledged to hire more Burmese speakers to monitor hate speech on Facebook, but the removal of the military-linked accounts shows a step-up in actions against those accused of promoting anti-Rohingya rhetoric.
The social media giant was previously accused by United Nations experts of helping incite violence in Myanmar and failing to take measures to stop the spread of hate and anti-Rohinyga propaganda on its platform.
