At least three people, including two teenagers have reportedly been killed after a plane crash landed at a summer camp in Switzerland.
The incident happened in the mountainous canton of Grunbunden in the east of the country.
Those killed included two 14-year-olds at the camp and the adult pilot of the plane.
A third teenager is believed to have been seriously injured.
All three are believed to been in the small single-engine plane, identified as a Piper PA28, as a ride organised by a local flying club, area police spokesman Roman Ruegg reported.
He said a group of tourists who had taken a gondola ride to explore the regions peaks and witnessed the plane plummeting to the ground.
An investigation into the accident has begun.
A police spokesman told Agence France Presse that the pilot was experienced and had taken up other teenagers in the plane earlier in the day.
A spokesman for the flying club, Aero Club, Yves Burkhardt told reporters his "world has collapsed".
Mr Burkhardt said the plane rides were supposed to cap off a week of activity at the youth summer camp which the club had been operating for 35 years.
