The largest refugee camp in the world, near the Bengal border town of Cox's Bazar, has been hit by a devastating fire.

At least 15 people were killed, 400 residents are still missing, 560 people were injured and thousands of houses have been destroyed, according to statements by the Red Cross and the United Nations.

According to the UN, at least 45,000 people have to look for new accommodation, while the Red Cross reports that 125,000 residents of the camp have been affected by the fire.

The Red Cross speaks of "the largest rescue operation ever".

Countless children would have lost their families in the sea of ​​flames and the ensuing panic.

Johannes van der Klaauw, spokesman for the UN Refugee Agency (UNHCR), calls the consequences of the fire "gigantic and devastating".

The cause of the fire has not yet been determined.

More than a million Rohingya refugees, including more than 400,000 children, live in camps in southern Bangladesh.

The vast majority fled in 2017 from neighboring Myanmar, 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.
