Flooding and landslides triggered by heavy rainfall have killed at least 50 people in Nepal in the past few days, with more deaths reported across the border in India and Bangladesh, officials said Sunday.
At least 30 other people were missing in Nepal, either swept away by swollen rivers or buried by mudslides since monsoon rains began pounding the region on Friday, Nepal's National Emergency Operation Center said.
The center said nine key highways remained blocked by floods and mudslides, and attempts were underway to open them up for traffic. Among them is the East-West Highway, which connects Nepal's southern districts.
