The overflowing Brahmaputra River, which flows through China’s Tibet, India, and Bangladesh, has damaged crops and triggered mudslides, displacing millions of people, officials said.

More than 2.75 million people in Assam have been displaced by three waves of floods since late May that has claimed 79 lives after two more deaths were reported overnight, a state government official said.

“The flood situation remains critical with most of the rivers flowing menacingly above the danger mark,” Assam water resources Minister Keshab Mahanta told Reuters.

Assam is facing the twin challenge of combating floods and the coronavirus pandemic. Out of 33 districts, 25 remained affected after the current wave of flooding, beginning a fortnight ago.

India is grappling with the novel coronavirus, which has infected nearly 1.1 million people and 26,816 have died from the COVID-19 disease, government data showed on Sunday.

In neighboring Nepal, the government asked residents along its southern plains on Sunday to remain alert as heavy monsoon rains were expected to pound the Himalayan nation where more than 100 have died in floods and landslides since June, officials said.

Some 110 people were killed and another 100 injured as landslides and flash floods washed or swept away homes, upended roads and bridges and displaced hundreds of others in 26 of the country’s 77 districts, police said.

Home ministry official Murari Wasti said the death toll was expected to rise as 48 people were still missing.

“Search and rescue teams are looking for those who are missing in different places but chances of finding them alive are slim,” Wasti told Reuters.

Barun Paudel of the weather forecasting office in the capital, Kathmandu, said heavy rains were expected to pound much of the mainly mountainous nation in the next four days.

“We have urged residents to remain alert against possible landslides and floods,” he said.

Landslides and flash floods are common in Nepal, India’s Assam and Bihar states during the June-September annual rainy season.

Nine people were killed and more than 30 were missing in Myagdi district, 200 km (125 miles) northwest of the capital Katmandu, where several houses were destroyed on Friday, district administrator Gyan Nath Dhakal said, Reuters reported.

“The toll is expected to increase as rescuers had just reached the remote site to look for victims,” Dhakal said, adding that 50 people had been plucked to safety using helicopters.

In neighboring Kaski district, seven people were killed, said a second government official in the tourist town of Pokhara.

Another seven were killed in the Jajarkot district in the far west.

“We are searching for eight people who are still missing,” said Kishore Shrestha, a senior police official.

In the southern plains bordering India, the Koshi River, which causes deadly floods in the eastern Indian state of Bihar almost every year, was flowing above the danger level, police said.

Landslides and flash floods are common occurrences in mountainous Nepal during the June-September monsoon every year.
