Several more villages were burned down on Saturday in a part of northwest Myanmar where many Rohingya Muslims had been sheltering from violence sweeping the area, two sources monitoring the situation said, according to Reuters.

The fires started on Friday when up to eight villages went up in flames in the ethnically-mixed Rathedaung region, have increased concerns that more minority Rohingya will flee to neighbouring Bangladesh.

Blazes on Saturday engulfed as many as four more settlements in Rathedaung, likely destroying all the Muslim villages in the area, the sources said.

"Slowly one after another, the villages are being burnt down - I believe that Rohingyas are already wiped out completely from Rathedaung," said Chris Lewa of the Rohingya monitoring group, the Arakan Project.
"There were 11 Muslim villages (in Rathedaung) and after the past two days all appear to be destroyed."

Independent journalists are not allowed into the area, where Myanmar says its security forces are carrying out clearance operations to defend against "extremist terrorists."

Human rights monitors and fleeing Rohingya say the army and ethnic Rakhine vigilantes have unleashed a campaign of arson aimed at driving out the Muslim population. Some 290,000 people have fled across the Bangladeshi border in less than two weeks, causing a humanitarian crisis.

Rathedaung is the furthest Rohingya-inhabited area from the border with Bangladesh and aid workers are concerned that a large number of people were trapped there.

The sources said that among the torched villages was the hamlet of Tha Pyay Taw. They were also concerned about the village of Chin Ywa, where many people sheltering from other burnings in the area had been hiding and two other settlements.

On Friday, the villages of Ah Htet Nan Yar and Auk Nan Yar, some 65 km (40 miles) north of Sittwe, capital of Rakhine state, were also burned along with four to six other settlements.

One source, who has a network of informers in the area, said 300 to 400 Rohingya who had been hiding at Ah Htet Nan Yar were now in the forest or attempting a perilous, days-long journey by foot in the monsoon rain towards the River Naf separating Myanmar and Bangladesh
