The flood struck around 9 a.m. local time on Wednesday, ravaging villages, roads and hydropower projects along the river. The official death toll has been creeping toward 600, with authorities warning it will likely continue to rise as search and rescue operations continue.
Among the nearly 2,000 people still missing, at least 90 are U.S. citizens, many of whom were on a religious pilgrimage to a sacred site in the region. Survivors, victims and missing persons from numerous other nationalities have also been reported.
The cause of the flash flood remains under investigation, but torrential rainfall and possible glacial lake outburst have been cited by officials as contributing factors. Ongoing recovery efforts are hampered by damaged infrastructure and difficult terrain.
