Nepal has shut schools for three days after landslides and floods triggered by two days of heavy rain across the Himalayan nation killed 151 people, with 56 missing, officials said on Sunday.

The floods brought traffic and normal activity to a standstill in the Kathmandu valley, where 37 deaths were recorded in a region home to 4 million people and the capital.

Authorities said students and their parents faced difficulties as university and school buildings damaged by the rains needed repair.
