Authorities in northern India say thousands of people are stranded after a Himalayan river burst its banks, washing away roads, bridges and dozens of homes.
Officials in Himachal Pradesh state said the raging waters of the Sutlej River have cut off vast areas in the east of the state. So far no casualties have been reported.
The floods were caused by a sudden rush of water from the Parechu River, one of the tributaries of the Sutlej. The Parechu overflowed Sunday after water levels in an artificial lake, created in the river in neighboring Tibet, grew dangerously high.
Also Sunday, state authorities evacuated more than 4,500 people from low-lying areas. Indian army troops are coordinating relief operations and air force helicopters are on stand-by.
