Stores reopened and traffic was returning to Nepal's capital three days after the Himalayan nation was shaken by a second major earthquake.

But thousands of people were still sleeping in tents scattered across the city on Friday, afraid that aftershocks might topple damaged homes.

Schools and colleges remained closed after Tuesday's magnitude-7.3 quake, which killed 117 people and injured 2,800. It struck just 2 1/2 weeks after the country was battered by a magnitude-7.8 quake that killed more than 8,200 people.

Government office buildings in Kathmandu have been badly hit, with many buildings developing cracks or collapsing altogether. Government officials from the National Planning Commission were working from a tent erected outside its building.

Outside Kathmandu, many roads linking the capital to outlying areas were heavily damaged.
