Bangladesh authorities are investigating the cause of a massive fire in a Rohingya refugee camp which has left 12,000 people without shelter.
Ednews reports citing foreign media that no casualties have been reported. But the blaze razed 2,000 shelters after spreading quickly through gas cylinders in kitchens, officials said.
Police are investigating if the fire was an act of sabotage. One man has been detained, local media reported.
The camp in the south-east is believed to be the world's largest refugee camp.
Most of its residents, Rohingya refugees, had fled persecution in neighbouring Myanmar.
On Monday, hundreds had returned to the area, known as Cox's Bazar, to see what they could salvage from the ruins.
The blaze had started at about 14:45 local time Sunday (08: 45 GMT) and quickly tore through the bamboo-and-tarpaulin shelters, an official said.
"Some 2,000 shelters have been burnt, leaving about 12,000 forcibly displaced Myanmar nationals shelterless," Mijanur Rahman, Bangladesh's refugee commissioner, told AFP news agency.
