Eight Israeli tourists were stranded in the Pin valley following flash flood triggered by thawing of glaciers along the Indo-Sino border in Lahaul-Spiti tribal district of Himachal, official sources said.
The local administration has surveyed the alternative route and the rescue work will begin on war footing from Saturday, Himesh Negi, Spiti SDM, said.
Local MLA Ram Lal Markandey and the district administrative officers, who had gone to inspect flash flood area on Friday, had a narrow escape when flooding suddenly re-occurred there.
The SDM said that the flash flood had cut off the entire Pin valley from the rest of the state as one-km-long road along with bridge had been washed off.
The trouble spot in the cold Himalayan desert near the China border is about 408km from Shimla, the capital of Himachal.
"Population of 2003 people of Sagnam and Kunghi panchayats have been deprived of road connectivity as flash flood in the Kiri brook has washed off the entire one-km stretch of road along with the bridge on Thursday and the flood water is still rising.
"Melting glaciers uphill are the reason for the flash flood as a lake spanning about 300mts area has been formed upstream," he said.
"Melting glaciers upstream has created a lake which is causing the continuous flooding and it could script many other flash floods too," said Markanday from the flood spot by phone.
