Five Dead and 40 Injured After Dutch Tour Bus Overturns in Swiss Alps

On late Thursday afternoon, September 10, 2026, a tour bus carrying 45 adult passengers crashed and overturned in the southeastern Swiss Alps, leaving five people dead and 40 others injured. The incident occurred on a road between the towns of Susch and Zernez in the Graubünden region. Swiss authorities and emergency crews responded with a massive rescue operation involving multiple helicopters and ambulances. An investigation is currently underway to determine what caused the vehicle to veer off the road in a construction zone.

Who was on board the bus?

The bus was carrying 45 adult passengers, most of whom were Dutch nationals, according to Swiss authorities.

Graubünden Cantonal Police spokesperson Roman Ruegg stated that the passengers were primarily Dutch citizens. The vehicle was operated by Oad, a travel company based in the Netherlands. According to reports from the BBC, the coach had departed from the Netherlands on Monday, September 7, 2026, on a multi-day trip.

Of the 45 passengers on board, five died in the crash. The remaining 40 passengers sustained injuries of varying severity. According to the Graubünden Cantonal Police, three individuals suffered serious injuries, seven sustained moderate injuries, and 30 suffered minor injuries.

How did the crash happen?

The crash occurred when the tour bus struck a safety barrier in a roadworks zone, veered off the road, and overturned onto its side.

The incident took place near Zernez, which serves as the gateway to the Swiss National Park, a mountainous reserve in the Engadine valley. There is currently a discrepancy in media reports regarding the exact route of the coach. The BBC reported that the bus was on a day trip to Switzerland from Austria, while Breitbart reported that the vehicle was traveling to Austria from Switzerland.

Additionally, there is a timeline inconsistency in initial reports. Breitbart stated that police spokesperson Roman Ruegg detailed passenger nationalities on Wednesday night, even though the crash did not occur until the following Thursday afternoon. The exact physical or mechanical cause of the collision remains unconfirmed.

How did emergency services respond?

Emergency services deployed seven rescue helicopters and 13 ambulance teams to transport the victims to local hospitals.

The helicopter response included aircraft from the Swiss air rescue company Rega, Alpine Air Ambulance, and Heli Austria. Local fire departments and the Plaiv road rescue service also assisted at the scene. Rescuers worked through the night, and the bus was successfully lifted and cleared from the accident site early Friday morning, September 11, 2026, according to Swiss broadcaster SRF.

What are officials saying about the incident?

Political leaders from both the Netherlands and Switzerland have expressed condolences to the victims and their families.

Swiss President Guy Parmelin wrote on X that he was "deeply shocked and dismayed" by the accident, offering condolences to the families of those who died and thanking the first responders. Dutch Prime Minister Rob Jetten stated that his thoughts were with "everyone involved," while Dutch King Willem-Alexander and Queen Máxima said their hearts went out to those affected by "this great tragedy." The tour operator, Oad, also released a statement expressing that their thoughts are with all those affected and their families.

What happens next?

Swiss prosecutors and cantonal police are actively investigating the cause of the crash, while the process of identifying the deceased continues.

The Graubünden public prosecutor's office and the cantonal police have launched a joint investigation. As of Friday, September 11, 2026, Swiss authorities had not yet officially identified the five deceased victims, and the identification process remains ongoing.
