At least 273 people have been killed and more than 1,300 remain missing after catastrophic flash floods and mudslides devastated communities along the Nepal–Tibet border.
The disaster struck on Wednesday after a massive collapse of glacier ice and rock sent a powerful surge of water, mud and debris through mountain valleys, sweeping away buildings, roads, bridges and other infrastructure.
In Nepal, at least 270 people have been confirmed dead and 826 are missing, while authorities in Tibet have reported three deaths and 558 people missing.
Hundreds of foreigners, including tourists and pilgrims travelling through the Himalayan region, are among those unaccounted for. Those reported missing include nationals from India, the United States, Malaysia, Australia, Britain and Canada.
Helicopters have been deployed as rescue teams struggle to reach communities cut off by destroyed roads and bridges. More than 5,000 security personnel have joined rescue efforts in Nepal, while over 100 people have been rescued from affected areas.
Bodies have also been recovered far downstream from the worst-hit areas, raising fears that the death toll could rise further.
Authorities are additionally monitoring a swollen lake upstream in Tibet amid concerns that further flooding or landslides could complicate rescue operations.
Scientists are still examining the precise sequence of events, but evidence indicates the disaster began with a major collapse of ice and rock in the Himalayas, which triggered a destructive chain of flooding and debris flows across the border region. (Newswire)
