Landslide occurred in Kalimpong on Tuesday after a low-pressure area hovering over sub-Himalayan Bengal and the neighbouring states of Sikkim and Bihar resulted in incessant downpour since Monday evening.
The rain triggered landslides and flooding in several places.
Multiple landslides were reported from Darjeeling and Kalimpong districts in Bengal and also the neighbouring state of Sikkim.
At least one person died and six were injured owing to the slides in the region.
Weather officials indicated inclement conditions would persist for at least another 24 hours.
