Four dead and eight injured after fire destroys Swiss residential building
Swiss police have confirmed that four people died and eight were injured after a fire destroyed a restaurant and residential building in Thusis, in the canton of Graubünden.
The revised toll establishes that the incident was a fatal residential fire rather than an unresolved missing-person search. Investigators must now determine its cause and how the building’s occupants were able—or unable—to escape.
Swiss police confirmed on Sunday, 23 August, that four people died after a fire tore through a restaurant and residential building in , in the eastern canton of , shortly after midnight on Friday, 21 August. Eight people were injured, including two seriously, while nobody remains missing, according to the . Updated: 27 August 2026, 10:00 CEST.
The authorities initially listed five people as missing. Police spokesperson Pascal Vetsch later told Swiss public broadcaster that one of them had also been recorded among the seriously injured, reducing the number actually unaccounted for to four. Search teams subsequently found all four victims inside the damaged building. Formal identification had not been completed when the police issued their latest public statement.
Fourteen occupants escaped from the burning property, the cantonal government said. Of the eight people injured, two sustained serious injuries, two were moderately hurt and four suffered minor injuries. Emergency workers treated casualties at the scene before transfers to hospitals in , Chur, Ilanz and Zurich, according to the initial police account carried by and French-language Belgian outlets DH and .
The said preliminary evidence placed the start of the fire on the building’s second floor. The property contained a restaurant at ground level and small residential studios above it. A collapsed stairwell and the unstable structure complicated access, forcing crews to dismantle the roof layer by layer with lifting equipment before investigators could search the interior safely.
Around 100 firefighters took part in the initial response, according to the police account reported by . The municipality arranged accommodation and meals for residents who could not return to the property, while a specialist care team supported survivors and relatives.
The fire’s cause remains unknown. The public prosecutor’s office and cantonal police are investigating both its origin and the circumstances surrounding the deaths. Authorities have not released the victims’ identities or nationalities, and no connection to Belgium has been announced. The incident therefore has no confirmed direct effect in Belgium, although Belgian travellers or residents with contacts in the area should rely on official Swiss updates until identification work is complete.
The next substantive developments will come from the forensic identification process and the fire investigation. Investigators must establish how the blaze began, how it spread through the mixed-use building and whether its internal layout affected evacuation. No timetable for those findings has been published.
Impact
Regional — The municipality of Thusis has provided accommodation and meals for displaced occupants, while regional hospitals treated the injured.
Local — Thusis authorities provided accommodation and meals to occupants displaced by the destruction of the building. Regional hospitals treated eight injured survivors, including two people with serious injuries. The loss of a mixed restaurant and residential property also leaves a local recovery task beyond the criminal and technical investigation. Municipal support is therefore focused on immediate shelter and food, while cantonal services continue examining the damaged, unstable structure and the circumstances of the deaths.
What it means for you
The incident creates no announced change to Belgian travel, safety or consular arrangements. Belgium-based readers with relatives or planned stays in Thusis should contact their accommodation provider directly if their booking involves the affected property or immediate area. Anyone seeking verified information should rely on Graubünden cantonal police and municipal updates, as the casualty search is complete but the cause remains under investigation. Do not treat preliminary reports about the second-floor origin as a final finding. No costs, compensation process or public deadline affecting Belgian residents has been announced.
