The Rohingya refugee camp in Bangladesh is destroyed by fire, leaving thousands homeless.

A massive fire ripped through a Rohingya refugee camp in Bangladesh’s southern district of Cox’s Bazar on Sunday, leaving around 12,000 people homeless. The cause of the fire is not yet determined, but an investigation is under way. Authorities are working with international and local humanitarian organizations to provide food and temporary shelters to those who have lost homes. Ninety facilities including hospitals and learning centers were burnt down, the Bangladesh branch of the United Nations refugee agency UNHCR tweeted on Sunday. Humanitarian organization Save the Children said Sunday’s fire was a “ghastly reminder that children stuck in the camps in Cox’s Bazar face a bleak future.” The UN’s International Organization of Migration (IOM) in Bangladesh said they are assessing the needs of people to provide support. An estimated 1 million members of the stateless Muslim minority Rohingya live in what many consider to be among the world’s largest refugee camps after fleeing a brutal campaign of killing and arson by the Myanmar military.
