A small plane carrying 22 people on board lost a popular tourist road in nepal's mountains on Sunday, an official said.
The Tara airline plane was on a scheduled 15-minute flight to the mountain town of Gomsom from the tourist town of Pokhara, 200 kilometres from Kathmandu, and lost contact with the airport control tower shortly after take-off.
A police official said that there was no information about the Twin Otter aircraft and that a search was under way.
Another police official said that six foreigners, including four Indians and two German nationals, were on board.
An Interior Ministry spokesman said two helicopters had been sent to conduct the searches, adding that visibility was poor. "Bad weather may slow down searches. The vision is so weak that we can't see anything."
It has been raining in the area for the past few days, but flights are operating normally.
