{{/usCountry}}The flood was triggered by a cloudburst in the higher reaches of the Rishi Dogri Valley. The strong flow of water swept away a bridge across the Sutlej River and left one person injured, the Indian Army said.
The army deployed its new generation equipment, the logistics drone high altitude (LDHA) system, to ferry essential items, including eatables, coconut water across the floodwaters to help sustain the stranded individuals through the night.
Army personnel also guided civilians to safer locations on higher ground and evacuated the injured person to the Regional Hospital in Reckong Peo.
