The Myanmar army has released the results of an internal investigation in which it exonerates itself of blame regarding the Rohingya crisis.
It denies killing any Rohingya people, burning their villages, raping women and girls, and stealing possessions.
The assertions contradict evidence seen by BBC correspondents of a crisis the United Nations has called "a textbook example of ethnic cleansing".
Amnesty International said the army's report was an attempted "whitewash".
The human rights organisation called for UN fact finders to be allowed in to the region.
Media access to the area has been severely restricted but on one tightly-controlled trip. Local Buddhist men setting a Rohingya village alight in front of armed policemen.
More than half a million people from the stateless and mainly-Muslim Rohingya minority have fled mainly-Buddhist Myanmar since August this year, after a counter-insurgency operation responding to Rohingya militants attacking police posts and killing members of the security forces.
Many who reached Bangladesh - some with bullet or other wounds - said Burmese troops backed by local Buddhist mobs had burned their villages and attacked and killed civilians.
But in a statement posted to Facebook, the military said it had interviewed thousands of villagers who backed up its denials. The villagers, it said, agreed that security forces:
did not shoot at "innocent villagers"
did not commit "sexual violence and rape cases against women"
did not "arrest, beat and kill the villagers"
did not steal silverware, gold, vehicles or animals from villagers
did not set fire to mosques
did not "threaten, bully and drive out the villagers"
did not set houses alight
It said "terrorists" from within the Rohingya community (which it called Bengali) were responsible for houses being torched, and that the hundreds of thousands of people who fled did so because they were instructed to do so and feared the terrorists.
A spokesman for Amnesty International said the military had "made clear it has no intention of ensuring accountability".
He added: "It's now up to the international community to step up to ensure these appalling abuses do not go unpunished."
The general who was in charge of the region has been transferred from his post, but no reason has been given for this move.
Major General Maung Maung Soe was "put in reserve", a Ministry of Defence spokesman said.
The Arakan Rohingya Salvation Army (Arsa) group, which says its aims are to "defend, salvage and protect" the Rohingya people, is made up of young men with home-made weapons and some foreign training, according to observers.
The refugee crisis prompted by events since August has resulted in an outpouring of global condemnation for Myanmar's de facto leader, Aung San Suu Kyi. Various accolades given to her when she was under house arrest at the orders of the military junta, and seen as the hope for democracy in the country, have now been revoked.
