The London-based rights group said Monday that eyewitness testimony and analysis of satellite images established that Myanmar's Rakhine state is being militarized at an alarming pace with the construction of army bases, helipads and roads built in villages that had been burned and bulldozed.
"What we are seeing in Rakhine State is a land grab by the military on a dramatic scale", said Amnesty's Crisis Response Director Tirana Hassan.
The report comes on the heels of a similar investigation published by Human Rights Watch in February, in which the organization alleged Myanmar's forces were demolishing Rohingya villages in order to erase any proof of human rights abuses that may have been committed in Rakhine.
Burma is allegedly building military bases on top of razed Rohingya villages, raising questions over the safety of hundreds of thousands of persecuted refugees who are due to be repatriated. "Myanmar's authorities are erasing evidence of crimes against humanity, making any future attempts to hold those responsible to account extremely hard".
"People are in a panic", one refugee in Bangladesh, who fled his village in January, told the rights watchdog. "No-one wants to stay because they are afraid of more violence against them".
The UN and other aid agencies say that the Myanmar did not create an atmosphere conducive for safe and dignified return of the refugees. "Not only are their homes gone, but the new construction is entrenching the already dehumanising discrimination they have faced in Myanmar".
Evidence of Myanmar's ethnic cleansing campaign against the Rohingya minority continues to mount as Amnesty International revealed the Burmese military is now conducting a "land grab" of areas where the besieged community used to live.
The violence also forced thousands of others to cross into Bangladesh. The images also show new refugee reception centres surrounded by security fences.
There are serious concerns that the Myanmar authorities are planning to house Rohingya in the centres for a prolonged period and restrict their freedom of movement.
Myanmar has denied it is covering up evidence, saying it is improving the standards of living in one of the country's poorest states.
"The remaking of Rakhine State is taking place in a shroud of secrecy".
"The global community, and in particular each donor state, has a duty to ensure that any investment or assistance it provides does not contribute to human rights violations".
Almost 700,000 Rohingya Muslims have crossed the border into Bangladesh since last August, clearing forests and camping on hillsides already crowded with more than 300,000 refugees from previous waves of migration.
