Cyclone Mora has hit the south-eastern coast of Bangladesh, killing at least six people. Most of them were killed by falling trees in the districts of Cox's Bazar and Rangamati, officials told the BBC.
Hundreds of houses were fully or partly damaged, the officials said. Significant damage is reported in refugee camps housing Rohingya Muslims from neighbouring Myanmar.
The authorities have moved hundreds of thousands of people to shelters. A farmer from Cox's Bazar, Rashid Mia, told the BBC he had lost everything: "The house is gone, all the furniture has also gone. The cyclone damaged my farm equipment. We came to this shelter just to survive."
About 20,000 houses in refugee camps for Rohingya were damaged, community leader Abdus Salam told AFP news agency. "In some places, almost every shanty, homemade of tin, bamboo and plastic, has been flattened," Mr Salam added. "Some people were injured, but no-one is dead [in the camps]."
Cyclone Mora made landfall at 06:00 local time (00:00 GMT) between the fishing port of Cox's Bazar and the city of Chittagong, with winds of up to 117 km/h (73mph), the country's meteorological department said.
It then weakened as it moved north, heading into India. A number of houses were also damaged in western Myanmar.
The Bay of Bengal is prone to storms and Bangladesh is often hit by severe weather during the monsoon season, from the middle to the end of the year. Last year, Cyclone Roanu hit coastal Bangladesh, leaving at least 24 people dead.
