Nepal-Tibet floods kill 160, 1,000 missing

A glacial collapse along the Nepal-Tibet border triggered a catastrophic flash flood that swept through valleys, killing at least 165 people and leaving more than 1,000 missing.

The disaster struck without warning, with witnesses describing a 'tsunami' of mud and rock.

Rescue operations are ongoing, with teams from Nepal, India, and China searching for survivors.

Scientists are examining whether an earthquake or climate change-induced instability caused the glacier to fail.
