At least 14 people have died after heavy rains triggered flash floods and landslides across Nepal, and disaster teams are searching for nine missing, police said Sunday.
Floods in neighbouring India and Bangladesh have also caused widespread damage and affected millions of people.
“Police are working with other agencies and local people to find the missing people,” said Nepalese police spokesman Dan Bahadur Karki.
People have died or are missing in several places, he said.
Monsoon rains from June to September cause widespread death and destruction each year in South Asia, but the number of deadly floods and landslides has increased in recent years.
Experts say climate change and increased road construction are making the problem worse.
Parts of Nepal have been receiving heavy rains since Thursday, prompting disaster management authorities in the Himalayan nation to warn of flash flooding in several rivers.
There have been reports of flooding in several low-lying districts bordering India.
Last month, 14 people were killed in Nepal in fierce storms that triggered landslides, lightning and flooding.
In India, floods have hit the northeastern state of Assam, killing six people in the past 24 hours, the Assam State Disaster Management Authority said Sunday.
That brings the death toll from torrential rains in the state since mid-May to 70, according to news agency PTI.
In lower Bangladesh, downstream from India, the disaster management agency said flooding had affected more than two million people.
Much of the country is made up of deltas where the Himalayan rivers, the Ganges and the Brahmaputra, meander towards the sea after passing through India.
The summer monsoon provides South Asia with 70 to 80 percent of its annual rainfall.
