Gangtok: Rescuers found more bodies overnight as they dug through slushy debris and ice-cold water in a hunt for survivors after a glacial lake burst through a dam in India’s Himalayan northeast, washing away houses and bridges and forcing thousands to flee.

Officials said the hundreds of rescuers recovered six more bodies early Saturday, bringing the death toll to 47. At least 150 people are still missing. The Lhonak Lake burst its banks on Wednesday after a cloudburst triggered torrential rains and an apparent avalanche, causing major flooding in Teesta River.

Nearly 4000 tourists were stranded in two locations, Lachung and Lachen in the northern part of the state, where access was severely restricted as the floods had washed away roads. But the bad weather has made rescue efforts more challenging, with authorities unable to deploy helicopters to assist those stuck in vulnerable areas.

26 people including seven Armymen were killed in the flash flood and affected over 25000 people damaged more than 1200 houses and washed away 13 bridges, bringing the picturesque Himalayan state to its knees.
