At least five mountaineers were killed and four are missing after their camp on a Himalayan peak in western Nepal was hit by a storm, police said on Saturday, in the country's worst climbing disaster in two years.

Sunday's storm had a wind speed of up to 70 kilometres per hour, demolished dozens of homes and uprooted trees and power lines in the northern Uttar Pradesh state.

A powerful dust storm and rain swept parts of north and western India overnight, causing house collapses, toppling trees and leaving at least 91 people dead and more than 160 injured, officials said Thursday.
