A deadly bus fire in the Swiss town of Kerzers has left at least six people dead and several others injured, prompting a major criminal investigation by authorities in the canton of Fribourg. The fire broke out on Tuesday evening on a regional bus operating in western Switzerland, rapidly engulfing the vehicle and leaving little time for passengers to escape. Initial reports from police indicate that the blaze may have been deliberately started by a passenger on board, although investigators are still working to determine the exact sequence of events.
The incident occurred around 6:25 p.m. local time and quickly drew emergency responders to the scene, including firefighters, ambulances, and helicopter rescue teams. According to statements from Fribourg cantonal police, the bus was completely consumed by flames by the time rescue teams arrived. Several passengers suffered severe injuries and were rushed to nearby hospitals, while others received medical treatment at the scene.
Witness accounts have suggested that a man inside the bus may have poured petrol on himself before setting himself on fire, though authorities have not officially confirmed this claim. Images circulating in local media showed the charred remains of the bus after the fire was extinguished, illustrating the devastating scale of the tragedy. Investigators and prosecutors have opened a criminal inquiry as officials work to clarify what caused the blaze and whether it was indeed a deliberate act.
Man Sets Himself on Fire in Kerzers
The fatal bus fire occurred in the town of Kerzers, located roughly 15 miles west of Switzerland’s capital city of Bern. The vehicle involved in the tragedy was part of the regional transport system and operated by PostBus, a company affiliated with the country’s national postal service. The bus was reportedly carrying passengers along its normal route when the fire suddenly broke out inside the vehicle.
Eyewitnesses described a chaotic and terrifying scene as flames spread rapidly through the bus. According to early reports gathered by local media, some passengers noticed unusual behavior from a man inside the vehicle shortly before the blaze began. Several witnesses later claimed that the individual appeared to pour petrol over himself and ignite it, triggering the fire that quickly spread through the interior of the bus. However, police officials have stressed that these claims remain unconfirmed and that investigators are carefully reviewing all available evidence.
Images published shortly after the incident showed the bus almost entirely destroyed by the blaze. Flames reportedly engulfed the vehicle within minutes, making escape difficult for those still inside. The speed at which the fire spread contributed to the high number of casualties and injuries. Emergency crews arriving at the scene found the bus completely burned out, with smoke still rising from the wreckage as they began rescue operations.

Police said that the names would only be made public after relatives had been notified. The number of injured passengers also added to the severity of the event, with several individuals suffering serious burns or smoke inhalation. The incident has shocked the local community and raised urgent questions about what exactly happened inside the bus in the moments before the fire erupted.
Possible Cause and Ongoing Investigation
Swiss authorities quickly launched a criminal investigation to determine the exact circumstances behind the tragedy. Prosecutors in the canton of Fribourg have taken charge of the inquiry, working alongside police investigators and forensic specialists to analyze evidence from the scene. Officials emphasized that while initial indicators suggest the possibility of a deliberate act, it is still too early to draw definitive conclusions.
A spokesperson for the Fribourg cantonal police stated during a press conference that investigators have “elements suggesting a deliberate act by a person who was inside the bus.” These early findings have prompted authorities to examine whether the fire may have been intentionally started by a passenger. At the same time, police have urged caution, noting that witness accounts and circulating reports must be verified before any firm conclusions can be made.

Some early reports indicated that the suspected individual may have doused himself with petrol before igniting the fire. However, officials have not confirmed these details and said that investigators are still reviewing video footage, witness testimony, and forensic evidence collected from the bus. Determining the precise cause of the blaze will require careful examination of the burned vehicle and any materials found at the scene.
The investigation is also focused on reconstructing the timeline of events leading up to the fire. Authorities are attempting to identify exactly when and where the suspected act may have occurred and how quickly the flames spread throughout the bus. This process involves interviewing passengers who survived the incident as well as analyzing physical evidence recovered from the wreckage.
Police have also asked residents and anyone who may have witnessed the incident to come forward with information. The area where the fire occurred was quickly cordoned off to allow investigators and emergency personnel to carry out their work safely. Forensic teams have been carefully documenting the scene while specialists attempt to determine whether accelerants or other substances played a role in fueling the blaze.
While investigations continue, officials have stressed that determining the motive behind any possible deliberate act remains a key part of the inquiry. Authorities have not released information about the suspected individual or whether that person was among those killed in the fire. The focus remains on gathering evidence and confirming the facts surrounding the tragedy before releasing further details to the public.
