A massive flood swept through Nepal’s northern Rasuwa district on Wednesday, damaging roads and power infrastructure as authorities scrambled to assess the scale of the destruction.

Videos shared by Nepal Police and others on social media showed torrents of muddy water crashing through mountain valleys in the Himalayan district bordering China.

“We do not exactly know the extent of damage, but the flood is big, and it could have damaged many settlements,” Nepal Police spokesman Abi Narayan Kafle told AFP.

“We have alerted people who are staying near the riverside to relocate… and deployed all our resources,” he said.

Prime Minister Balendra Shah convened an emergency meeting of the National Disaster Risk Reduction and Management Authority to take stock of the situation.
