A massive fire at a crammed camp for Rohingya Muslims in southern Bangladesh has left thousands of the refugees homeless, a fire official and the UN said.

No casualties were reported at Balukhali camp in Cox’s Bazar district on Sunday, said Emdadul Haque, a fire service official.

The UNHCR in Bangladesh said in a tweet that Rohingya refugee volunteers responded to the fire with the agency and its partners providing support. It provided no further details.

The blaze erupted at Camp 11 in Cox’s Bazar. Most of the refugees fled a military-led crackdown in Myanmar in 2017, and the fire left some of them homeless again.

“We currently don’t have an estimate for damages but there are no reports of casualties,” Rafiqul Islam, additional police superintendent at Cox’s Bazar told Reuters.

He added that the blaze was under control and senior officials from the fire, police and refugee relief departments were at the site.

Faruque Ahmed, a local police official, said the cause of the fire was not clear. Neither police official gave an estimate for the number of homes destroyed.

“I couldn’t save anything. Everything burnt to ashes. Many are without homes. I don’t know what will happen to us,” said 40-year-old refugee Selim Ullah, a father of six children.

“When we were in Myanmar we faced lots of problems... our houses were burned down, he said. “Now it has happened again.”

The refugee camps in Cox’s Bazar are prone to such blazes. A massive fire in March 2021 killed at least 15 refugees and destroyed over 10,000 homes.

Conditions in Myanmar have worsened since a military takeover in 2021, and attempts to send back the refugees have failed.
