A cloudburst led to flash floods in the high altitude villages of Dharali on the way to Gangotri on Tuesday with the raging waters sweeping away several houses and leaving at least four people dead, officials said.
Dharali is the main stopover on way to Gangotri and home to many hotels, restaurants and home stays.
The devastating flashflood came in the wake of a cloudburst somewhere in the catchment area of the Kheer Ganga river, locals said.
According to initial reports, at least four people have died, Uttarkashi District Magistrate Prashant Arya told reporters. An Army team from Harsil has been rushed to the spot.
About 10-12 people could be buried under the debris, Rajesh Panwar, a villager, told PTI. He said 20-25 hotels and homestays may have been washed away.
Prime Minister Narendra Modi expressed condolences to people affected by the flashfloods and assured that no stone is being left unturned in providing assistance.
