NEW DELHI - The death toll from Nepal's earthquake has jumped to 3,218, a police official said on Monday.

The official said 6,538 people have been injured in Saturday's quake, the worst in the country in 81 years.

In Kathmandu, thousands of people had spent the night on pavements, in parks and open fields in chilly temperatures, too afraid to return to their ramshackle homes.

Among the buildings collapsed in the capital was the landmark nine-storey Dharahara tower, a major tourist attraction.

Police said about 150 people were believed to have been in the tower at the time of the disaster.

Hospitals in the Kathmandu Valley, which were swarming with patients,were running out of emergency supplies and space to store corpses.Some doctors were treating patients in makeshift tents.

In Mount Qomolangma's worst disaster, the bodies of 18 mountaineers were recovered from the mountain on Sunday after being caught by in the quake-triggered avalanche.

Six helicopters had managed to reach the mountain after the weather improved, reports said.

The powerful tremor, which was followed by at least 14 aftershocks, also lashed parts of India, and was felt in Bangladesh and Pakistan.

Some 61 people died from the quake in India and a few in several other countries.

Aftershocks were reported throughout the day, including the 6.7- magnitude follow-up one that struck in the afternoon.
