Nepal says missing plane with 22 on board crashed

"Search and rescue troops have physically located the plane crash site," army spokesperson Narayan Silwal said on Twitter, posting a picture of the wreckage with the plane's tail number clearly visible and parts of the aircraft shown scattered on the edge of a mountain.

Four Indians, two Germans and 16 Nepalis were on board the plane, a De Havilland Canada DHC-6-300 Twin Otter operated by privately owned Tara Air, according to the airline and government officials.

The aircraft was on a 20-minute flight before losing contact with the control tower.

It had taken off from the tourist town of Pokhara, 125 kilometres (80 miles) west of the capital, Kathmandu, and was bound for Jomsom, about 80 km (50 miles) northwest of Pokhara, a popular tourist and pilgrimage site.

Flight-tracking website Flightradar24 said the aircraft, with registration number 9N-AET, made its first flight in April 1979.

Deo Chandra Lal Karna, a spokesperson for the Civil Aviation Authority of Nepal (CAAN), said five helicopters were ready to help with the rescue process.

Nepal, home to eight of the world's 14 highest mountains, including Everest, has a record of air accidents. Its weather can change suddenly and airstrips are typically located in mountainous areas that are hard to reach.
