Nepal-Tibet Border Flash Floods Kill At Least 18
A huge amount of mud, rock and water rushed through areas near Nepal’s border with Tibet.
The flood destroyed homes, roads, bridges and some electricity projects.
News reports gave different early death tolls, ranging from nine to at least 18 people.
Nepal officials said 384 travellers were reported missing, but they were still checking who was actually unaccounted for.
Videos showed people running away as water and debris swept through villages and border facilities.
Rescue teams had trouble reaching some places because roads were blocked and helicopters could not land.
Officials warned people living near rivers to move to safer ground.
They also feared another flood because debris was still blocking part of the river upstream.
Flash floods and mudslides swept away homes, bridges, roads and power projects along Nepal’s border with Tibet.
Reports put Nepal’s death toll at nine initially and at least 18 in a later account.
Nepal’s Tourism Board listed 384 travellers as missing, including 291 foreigners and 93 Nepalis, pending verification.
Videos showed people fleeing and floodwaters destroying buildings, vehicles and bridges, including one in Malekhu.
Rescuers faced blocked roads and dangerous conditions, while authorities warned that a second flood could occur.
