NEW DELHI — A cyclone tore through parts of Bangladesh on Tuesday, destroying the homes of thousands of Rohingya refugees who had fled the violence in Myanmar over the last several years.

The authorities in the affected districts of Cox’s Bazar and Chittagong evacuated 450,000 people before Cyclone Mora, officials said.

In the coastal border district of Cox’s Bazar, where a majority of the Rohingya in Bangladesh live, more than 17,000 houses were destroyed and more than 35,000 were damaged, said Mohammad Ali Hossain, the deputy commissioner there. Four people were killed in the district, and 60 were injured. Officials in Chittagong said no casualties had been reported as of Tuesday afternoon.
