Nepal Flash Floods Kill 270, Spur Rescue and Relief Efforts
Severe flash floods swept through parts of Nepal and nearby border areas.
At least 270 people died, and hundreds or possibly more than 1,000 people were missing, depending on the figures reported.
The floods damaged bridges, roads and communities.
Many Indian nationals and foreign tourists were stranded.
Officials said a glacier-related event, such as an ice avalanche or landslide, may have caused the sudden rise in water.
China disputed Nepal’s account of what started the flooding.
India sent food, medicine and other emergency supplies to Nepal.
Indian and Nepali authorities also created helplines and control rooms to help affected people.
Rescue teams were still searching for missing people and assisting those trapped by the disaster.
At least 270 people were killed and more than 800 remained missing after flash floods struck Nepal’s Bhote Koshi and Trishuli river systems.
The disaster stranded Indian nationals and foreign tourists, while border communities in Nepal and Tibet suffered extensive destruction.
Officials linked the flooding to a glacier-related event, but China rejected Nepal’s claim that a collapsed structure in Tibet triggered the disaster.
India sent emergency supplies, including 37.5 tonnes of humanitarian material, medicines and food packets, after an earlier 10-tonne aid shipment.
Authorities in India and Nepal opened helplines and control rooms as rescue efforts continued for stranded tourists and missing people.

Cause of the flooding
Nepal and Disaster Officials
Nepali officials and the Nepal National Disaster Risk Reduction and Management Authority said an ice avalanche, snow-rock landslide, glacier-related flood or bursting debris lake may have triggered the flooding near the Nepal-China border.
China and Chinese Authorities
China rejected Nepal’s claim that a collapsed “geological disaster dam” in Tibet triggered the floods, calling the allegation “fake news.” Beijing said the disaster originated in Nepal after a glacial collapse caused massive mudslides.
