Tens of thousands of people lost their homes on Monday in a devastating fire in a Rohingya refugee camp in southern Bangladesh.

An unknown number of residents did not survive the fire, aid organizations and local authorities report.

Images show a huge blaze sweeping through the Balukhali camp in the town of Cox's Bazar.

Thousands of huts and tents have gone up in flames and people are looking for what may be left of their belongings.

The fire is not yet under control.

Firefighters are trying to prevent the fire from spreading further, a spokesman for UNHCR, the United Nations refugee agency, told

Eyewitnesses say several people have died, but the number of deaths has not yet been confirmed.

The cause of the fire has also not yet been determined.

Meanwhile, various aid organizations are concerned about the lack of medical facilities in the camp.

They fear that this will cause more deaths.

According to the UNHCR, hundreds of volunteers from various aid organizations have volunteered to help.

Rohingyas fled genocide in Myanmar

More than a million Rohingya refugees live in camps in southern Bangladesh.

The vast majority of them fled neighboring Myanmar in 2017, where the military committed genocide against the Muslim Rohingya minority.

The Rohingyas live close together in the refugee camps, causing regular fires.

Monday's fire was the biggest to date, aid organization Save the Children reports.

To ease the pressure on the overcrowded camps, Bangladesh started relocating Rohingyas to new homes on a remote island last year.

The government sees this as a solution, but human rights organizations are very concerned about the new location, as it would be very vulnerable to storms.
