A dozen people were still missing and authorities warned the death toll could rise as rescue workers struggle to reach bodies buried in the landslides in the Cox's Bazar and Bandarban areas of southern Bangladesh, the Press Trust of India reported.
Four separate landslides struck Cox's Bazar and Bandarban after torrential rains loosened hilltops, sending mud cascading downhill.
Police said mudslides killed at least 25 refugees in the Ukhia and Teknaf sub-districts, bordering Myanmar and home to thousands of ethnic Rohingya refugees.
Landslides also washed away army barracks in Cox's Bazar, killing 18 people, including six army members. Some army members were still reported trapped after landslides buried the camp and 20 vehicles parked there.
A depression in the Bay of Bengal brought the heavy downpours. More rains are forecast.
