PATNA, India — Devastating floods triggered by seasonal monsoon rains have killed more than 950 people and affected close to 40 million across northern India, southern Nepal, and northern Bangladesh, officials said Thursday.
The rains have led to wide-scale flooding in a broad arc stretching across the Himalayan foothills in the three countries, causing landslides, damaging roads and electric towers, and washing away tens of thousands of homes and crops.
The northern Indian states of Bihar, Uttar Pradesh, West Bengal, and Assam in the remote northeast are the worst hit, accounting for 680 deaths, most of them from drowning, snake bites, or landslides.
South Asia’s monsoon rains run from June to September.
Disaster management authorities in Bihar said the state’s death toll of 367 could go up further as flood waters recede and bodies are recovered from submerged houses.
Army soldiers and volunteers have evacuated around 770,000 people from inundated areas. Of these, some 425,000 were living in 1,360 relief camps set up in school and government buildings, said Avinash Kumar, a Bihar state official.
In neighboring Uttar Pradesh, the state government said around 2.3 million people in 25 districts have been affected by the floods when at least three major rivers overflowed their banks, entering fields and homes.
An Uttar Pradesh government spokesman blamed the unprecedented flooding on the release of water from dams in upstream Nepal.
‘‘Rains have been intense but the release of water from Nepal has aggravated the situation,’’ said Manish Sharma.
Army troops have been helping to evacuate people marooned on rooftops or trees, while air force helicopters dropped packets of food, drinking water, and medicines to those camping on higher ground, mostly along highways.
Meanwhile, the state administration was bracing for the threat of infections as flood waters recede. Health workers have begun sending supplies of mosquito repellent, bleaching powder, and water purification tablets to the worst-hit areas, said health official Badri Vishal.
