At least 20 people are feared dead after a vintage World War II aircraft crashed into a Swiss mountainside, local reports said on Sunday.
All 20 people on board were killed, police said Sunday, Aug. 5, 2018.
Authorities have provided few details about those on board JU-Air's plane which crashed on the west side of the Piz Segnas Mountain in the canton of Graubuenden on Saturday.
Among those killed were 17 people from Switzerland and three people from an Austrian family, including a couple and their son.
The German-built Junker JU52 HB-HOT aircraft, dating from 1939 and nickamed "Iron Annie", was a collectors' aircraft.
Operator JU-Air said it was saddened by the news and it had set up a helpline for relatives.
The investigation, complicated by the vintage plane's lack of a "black box" flight recorder, will take several days.
The veteran plane is operated by Ju-Air, a company based in Duebendorf, near Zurich, that offers panoramic flights with old-time Junker Ju-52 planes.
Daniel Knech of the Swiss safety investigation service SESE said the crew did not have time to send out a distress signal.
The company's flight operations were suspended, it said.
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 maintenance inspection in July. No survivors have been found.
