Twenty people have died after a World War II vintage aircraft crashed into a mountainside in eastern Switzerland, police say.
The aircraft crashed about 2540m above sea level, on the western side of a 3000m peak called Piz Segnas.
Ju-Air said one of its aircraft had been involved in the accident on Saturday.
JU-Air CEO Kurt Waldmeier told reporters that the plane had undergone a maintenance inspection in July.
Officials said 11 men and nine women were killed, most from Switzerland but also a couple and their son from Austria.

The plane was operated by JU-Air, an association set-up to keep the planes flying after they were taken out of service by the Swiss Air Force in 1981.
There was no immediate word on the cause of the crash, and officials said they expect a complex investigation given that the 79-year-old plane was not equipped with black boxes.
