Rohingyas are fleeing the violence-hit Rakhine state and seeking safety in Bangladesh
A military campaign to wipe out Rohingya insurgents has rained violence down on Myanmar's Rakhine state, sending nearly 390,000 Muslim Rohingya refugees fleeing for sanctuary in Bangladesh.
Around 30,000 Rakhine Buddhists and Hindus have also been displaced, as ethnic and religious hatreds carve through the western state.
Access to the epicentre of unrest -- the northern wedge of Rakhine -- has been blocked by the government as the crisis unfolds.
But the weary and wounded Rohingya arriving in Bangladesh have told consistent but unverifiable accounts of village massacres, with soldiers and vigilante mobs teaming up to empty out communities and burn them to the ground.
The UN has accused Myanmar of waging an ethnic cleansing campaign against the Rohingya, a stateless group that the Buddhist-majority country refuses to recognise as citizens.
The government refutes the accusations, instead saying the army has carried out targeted operations to snuff out the militant group, whose attacks on police posts in late August unleashed the massive military response.
Here is what we know about who is left in violence-ravaged Rakhine, where tens of thousands of people are believed to still be on the move.
A census published in 2015 said three million people lived in Rakhine, including an estimated 1.1 million Rohingya.
Rakhine's northernmost Maungdaw district was home to around three quarters of that population, according to government figures.
But nearly forty percent of its Rohingya villages have been completely abandoned in the past three weeks, said government spokesman Zaw Htay.
"There are 176 villages where the whole village fled," he told reporters Wednesday night, out of 471 Rohingya communities in total.
The recent refugee arrivals in Bangladesh amount to more than a third of the total number of Rohingya once based in Myanmar.
Tens of thousands of ethnic Rakhine Buddhists and Hindus have also been driven from their homes since late August, saying they were targeted by the Rohingya militants.
On Thursday Myanmar's government said some 4,000 people had started trickling back to their villages in Maungdaw as clashes between the army and militants ebbed, without specifying their ethnicity.
Myanmar's Information Committee has said over 7,000 homes have been destroyed by fire across at least 59 villages -- the vast majority belonging to "Bengalis" as the government pejoratively calls the Rohingya.
New satellite images released by Amnesty International on Friday showed that more than two dozen villages in the Rohingya-majority area had been set alight since August 25, with patches of grey ash marking the area where structures had stood.
AFP reporters on government-steered press trips have seen abandoned villages and homes reduced to ashes.
Columns of smoke from the gutted villages have also been visible almost daily from across the Naf river in Bangladesh, where the Rohingya refugees are massing in ramshackle camps.
Rohingya refugees say Myanmar officers and Buddhist vigilantes started the fires after driving them out of their homes with gunshots and other threats, a tactic that Amnesty has described as an "orchestrated campaign" of ethnic cleansing.
Myanmar authorities deny that, saying the militants have torched the villages in a bid to attract global sympathy.
People on the move
Tens of thousands of Rohingya are believed to still be trekking through the monsoon-soaked area.
For those fleeing fire-hit areas further south, it may take weeks to cross over difficult terrain, blanketed by security forces, to reach the Bangladesh border.
Aid groups have been unable to access northern Rakhine since the violence erupted in late August, compounding the humanitarian crisis.
"Thousands, perhaps tens of thousands, may be trapped in remote areas far from the border with limited food and medical supplies and are unable to reach safety," said Pierre Peron, a spokesman for the UN Office for the Coordination of Humanitarian Affairs.
Rohingya who have stayed in their villages are living in fear and struggling to survive without the food deliveries that have supported their impoverished communities for years, said Laura Haigh from Amnesty International.
"They are essentially locked in and markets are not functioning," she told AFP.
Myanmar has said it will establish camps in Rohingya-majority areas of Maungdaw to provide relief, but details of the project are scant.
On Thursday the Information Committee said shelters will be set up for Muslims "who can guarantee they are no way connected to the terrorists".
Government spokesman Zaw Htay has also said the country would not allow all of those who crossed into Bangladesh to return -- comments likely to fuel allegations Myanmar is intentionally ejecting the Rohingya, whose presence in Myanmar has incensed powerful Buddhist nationalists for years.
"Some reached the other side of border. If they come back, we cannot accept all of them," Zaw Htay said, adding that returnees would need to be "scrutinised".
