Flash floods slammed into mountain towns near the Nepal–Tibet border on Wednesday, hitting with a sudden wall of mud and water that wiped out roads, bridges and entire settlements. Videos from the area show people trying to run as the surge crashes through, sweeping away buses, trucks and buildings in seconds. The flooding tore through the Rasuwa region and nearby valleys, leaving more than one hundred people dead and hundreds more missing, including tourists. Homes along the river were buried, communication lines were destroyed and rescue teams struggled to reach remote areas in dangerous terrain. Officials said the disaster was triggered by an avalanche from a glacier that blocked a river and then released a violent surge downstream. The region has been warming faster than most of the world, making heavy rains, landslides and glacier melt more common. Researchers say ice loss in the Himalayas has been speeding up for years, raising the risk of sudden floods like this one. Rescue crews are still searching through wreckage, and the full number of casualties may take days to uncover as entire communities were swept away.
