Six people were injured when their helicopter crashed Thursday on the Swiss alps, Swiss police said.
"The accident took place at about 12:30 pm on the Diablerets glacier around Tour St-Martin," said Jean-Marie Bornet, spokesman from canton Valais.
"The helicopter of company Heliswiss crashed certainly while trying to land," he added.
All onboard, including five passengers and a pilot, were injured in the accident which occurred at about 3,000 metres (10,000 feet) above sea level.
"Four were moderately injured and two others slightly hurt," said Bornet.
Weather conditions were good, said police, noting that there was no fog at the time of the accident.
An investigation has been launched to determine the cause of the crash in western Switzerland.
It marks the second air accident in less than a week in the Swiss alps.
On Friday, a private plane crashed in the canton of Valais, at a similar altitude. The pilot and four French passengers were dead by the time rescuers arrived on site.
