Three videos show large plumes of smoke rising from Rohingya villages as recently as Friday afternoon.
One of the villages was already deserted.
Satellite images also showed smoke rising from burned structures.
Local sources told Amnesty that the fires were started by Myanmar security forces and local mobs.
“Almost three weeks later, we can see in real time how there is no let-up in the campaign of violence against Rohingya in northern Rakhine State. Rohingya homes and villages continue to burn, before, during and after their inhabitants take flight in terror. Not satisfied with simply forcing Rohingya from their homes, authorities seem intent on ensuring they have no homes to return to.”
Hasan called for action from world leaders.
“The time has come and gone for giving Myanmar’s military and political leadership the benefit of the doubt. The international community must be unequivocal in its condemnation and take effective action to halt this ethnic cleansing campaign as well as bring the perpetrators to account,” she said.
Two other videos near Buthidaung showed a village in flames on Friday. Activists, including a source in Rakhine, told Amnesty the burning began between 1:30pm and 2:00 pm.
Satellite images taken on Sept 16 and Sept 22 showed a village had been burned to the ground over the course of a few days. Satellite sensors had also detected recent fire activity in the village.
A violent military crackdown following militant attacks on Aug 25 led to nearly 429,000 Rohingya refugees fleeing across the border to Bangladesh.
On Sept 19, Myanmar’s de-facto leader Aung San Suu Kyi, in her first address since the start of the latest violence, claimed there had been no conflict or clearance operations since Sept 5.
The following day Myanmar Vice President Henry Van Thio told the UN that the country’s security forces had been ordered to take ‘full measures’ to avoid collateral damage and harming innocent civilians.
