The two Swiss, born in 1996 and 1997, were roped for the ascent. The two men fell from the north face at a height of 4,140 meters and died on the spot. The Valais police announced this on Wednesday evening.
The reasons for the tragedy are still unclear. The public prosecutor’s office and the Valais canton police have launched an investigation.
The canton police, the Valais rescue organization, the Zermatt mountain rescue service and Air Zermatt were called to help.
