'High risk' of lake bursting and causing second flood, warns China

On the Nepal-China border on 28 August 2026, a glacier collapse and deadly flash floods struck the area. Satellite images show that bedrock and glacier collapsed, then rivers flooded. China said a glacier collapse in Nepal was likely behind the flash flood. Communications along the border were cut, the death toll rose to at least 579, and the number of missing passed 2,400.

China warned of a 'high risk' of a lake formed by debris bursting and causing a second flood. The lake began to overflow, and Nepal and China briefly halted rescue efforts, then resumed them after the threat eased. Survivors described running for their lives.
