Indian officials say at least 33 people are dead and many others trapped, following heavy monsoon rains that triggered floods and landslides in the country’s Himalayan region.

On Sunday night a cloudburst in mountainous Himachal Pradesh state’s Solan district killed nine people, and 12 people were pulled out from under mud and debris after two landslides in Shimla, the state’s capital.

Disasters caused by landslides and floods are quite frequent in India’s Himalayan north during the June-September monsoon season.

Scientists say such events are becoming even more frequent as global warming contributes to the melting of glaciers there.
