Swiss police say all five people who died in the crash of a private plane on Friday were French citizens.

Police in the southern Swiss canton (state) of Valais say the victims were a 58-year-old Switzerland-based pilot and a family he was taking on a sightseeing flight over the Alps.

The family included a 42-year-old woman, a 41-year-old man, a 15-year-old girl and a boy of 11. Police provided no further details Saturday about the identities of the deceased.

The twin-engine plane crashed at an altitude of 9,200 feet (2,800 meters) in the Val d'Anniviers near the border with Italy.
