A glacial collapse triggered the catastrophic flash flood in Nepal and Tibet that roared down valleys, wiping out entire villages and leaving a preliminary death toll of at least 165 people, the US Geological Survey said. Rescuers on Thursday raced to locate the hundreds missing, including nationals from India, the US, UK, Australia and Canada.

Terrifying videos from the event on Wednesday showed a massive wall of water crashing down on the border as people attempted to flee. Trucks were upended and houses, roads ⁠and power projects swept away in Nepal, while ​officials in Tibet said they feared “major casualties” after a mudslide hit a border land crossing.
