A horrific bus fire that claimed six lives in the Swiss town of Kerzers is being treated as a deliberate criminal act after witnesses reported a passenger dousing themselves in fuel.

The yellow PostBus was travelling through the main street of the canton of Fribourg at approximately 6:25 pm on Tuesday, 10 March, when it suddenly became a 'fireball.'

Fribourg cantonal police spokesperson Frederic Papaux confirmed that investigators have 'elements suggesting a deliberate act by a person who was inside the bus.'

While six people have been confirmed dead, five others were injured—including a paramedic—with three remaining in a critical condition after being airlifted to specialist units.

The tragedy has sent shockwaves through Switzerland, occurring just months after the devastating New Year's Day fire in Crans-Montana that killed 41 people.

Witnesses recalled seeing panicked passengers clamouring to escape, some leaping out of windows and others frantically seeking a way out.

'After rushing to the scene, rescue teams noted that the vehicle was totally engulfed in flames,' the officials stated.

In Kerzers, Switzerland, a bus fire killed six people and injured several others. Authorities suspect arson.

Police Suspect 'Voluntary Action'

The first investigation by the Swiss police provides an alarming clue: the fire was most likely the result of an act of omission. According to an official, there are indications that someone on the bus intentionally set the fire.

'At this stage, we have elements suggesting a deliberate act by a person who was inside the bus,' he said, adding that the 'fire left at least six dead and five injured, three of them seriously.'

The police are now out searching for witnesses who may have observed suspicious activity in advance.

The authorities denounced it as a 'pathetic and unaccountable act of violence.' The inquiry aims to determine the motives behind what appears to be a carefully orchestrated attack.

'We have no indication that suggests we might be dealing with a terrorist attack,' state councillor Romain Collaud said.

According to RTS, the alleged perpetrator was 'known to the authorities for mental instability problems.' He resided in the canton of Bern.

It is the second fire disaster in Switzerland in the year after a fatal bar fire in Crans-Montana that caused the death of 41 people.

National Mourning and Presidential Response

The names of six dead individuals have not been declared, and the three injured victims remain admitted in critical condition. Emergency workers, including firefighters and paramedics, arrived early, but the magnitude of the fire impeded rescue efforts.

Swiss President Guy Parmelin expressed his 'shock and sadness' over the event, which marks the second mass-casualty fire in the country in early 2026.

'It distresses and saddens me that once again people in Switzerland have lost their lives in a severe fire,' Parmelin posted on X. 'The circumstances are being investigated. To the relatives of the deceased from Kerzers, I extend my condolences. And I think of the injured and the rescue workers.'

PostBus CEO Stefan Regli described the event as a 'terrible tragedy' for the national postal service, which serves as the backbone of transport for Switzerland's rural communities. Psychological support teams have been deployed to assist both surviving passengers and the first responders who arrived at the grisly scene.

A Community In Shock

The investigation now shifts to the Fribourg public prosecutor's office, which is working to confirm the identity of the alleged perpetrator and their motive.

While local residents have placed flowers at the scene of the charred vehicle, the 'voluntary' nature of the act has left a quiet town grappling with an incomprehensible act of violence. With the perpetrator reportedly known to authorities in Bern for 'mental instability,' the focus will likely turn to the monitoring of high-risk individuals on public infrastructure.

For the people of Kerzers, the yellow PostBus, once a symbol of Swiss reliability, now serves as a reminder of a dark and unexplained Tuesday evening.
