At least 15 people died and over a dozen were missing after landslides and flash floods triggered by several days of heavy rain hit northern India, officials said Tuesday.

Officials in the Himalayan state of Uttarakhand said 10 people were killed in fresh landslides on Tuesday after five died in similar incidents on Monday.
Five of the deceased were killed after a cloudburst -- an ultra-intense deluge of rain -- triggered a landslide, completely burying a house along with its inhabitants in the town of Nainital early Tuesday.
"We have recovered five bodies from the disaster site and a further search is on," local official Prateek Jain told AFP.
Another landslide in the northern Almora district left five people dead after huge rocks and a wall of mud demolished and engulfed their home.
