KATMANDU, Nepal - A plane returning from a sightseeing tour of Mount Everest crashed while attempting to land in Nepal on Sunday, killing all 19 people on board, including 13 foreigners, officials said.

Ten Indians, two Americans and one Japanese were among the victims, Tourism Secretary Ganeshraj Joshi said.

The turboprop plane belonging to Buddha Air was also carrying three Nepalese passengers and three crew members when it crashed in Bisankunarayan village, just a few kilometres south of the capital, Kathmandu.

A witness, Haribol Poudel, told Avenues Television that the plane hit the roof of a house in the village and broke into several pieces. No casualties were reported on the ground.

Rewant Kuwar, an official at Kathmandu's international airport rescue office, said 18 bodies were pulled out of the plane's wreckage, and another victim died after being rushed to a hospital.

The Beechcraft 1900D plane -- manufactured by Raytheon Aircraft, now known as Hawker Beechcraft -- had taken the passengers on a one-hour "mountain flight" and was returning to Kathmandu.

The government has ordered an investigation into the crash.

The weather Sunday morning was foggy and the visibility was poor around Kathmandu, according to meteorologist Rajendra Shrestha. The surrounding mountains were enveloped in fog and it was raining at the time of the crash.

The bodies were flown by army helicopter to Kathmandu airport and transported to the Tribhuwan University Teaching Hospital for post-mortems.

Relatives of the Nepalese victims waited outside the hospital to claim the bodies, but were told by police that they would only be able to do so Monday. Most Nepalese believe that people have to be cremated within a day of their deaths.

Officials from the Indian and U.S. embassies visited the hospital but did not speak to media.
