DHAKA, Bangladesh -- At least 48 people have been killed in landslides triggered by strong rains in three hilly districts of southeast Bangladesh, officials and media reports said Tuesday.

Large chunks of mud swept over many thatched homes after the rains began early Monday across the South Asian country due to a tropical depression.

Rescue operations were underway but many remote areas were difficult to reach, said Reaz Ahmed, a senior disaster management official.

"The death toll could rise since many areas remain cut off," he said.

Bangladesh, a delta nation of 160 million people, is prone to natural disasters such as cyclones, floods and landslides. Many people in hilly regions ignore authorities' calls to avoid constructing homes on slopes.
