Firefighter dies after explosions in evacuated Brussels building

Updated 16 August 2026, 15:30 CEST — A Brussels firefighter died and three other people were injured on Friday, 14 August, after explosions struck an evacuated building on Treurenberg in central Brussels, according to Het Nieuwsblad and BRUZZ. Emergency crews had been responding to a gas leak reportedly caused when a contractor drilled into a gas pipe.

BRUZZ reported that the building was evacuated after the pipe was damaged. Explosions followed while emergency personnel were dealing with the incident. The available reports confirm the firefighter’s death and three injuries, but they do not yet provide a verified public account of the sequence inside the building or the condition of each injured person.

The incident occurred in the Treurenberg area, also known in French as Mont des Larmes, close to Brussels’ administrative and historic centre. The evacuation reduced the number of people exposed inside the property, although firefighters and other responders remained at risk as they worked to secure the leak.

Belgian Civil Security guidance treats a confirmed gas release and an explosion as distinct operational categories. It states that damaged gas infrastructure creates risks including fire, explosion and asphyxiation. Brussels Fire Brigade identifies gas leaks, hazardous-material releases and explosions among the emergencies handled by its specialist teams.

The death places the focus on how the damaged pipe was identified, what readings were taken after the evacuation and whether the gas supply had been isolated before the explosions. Those questions require findings from investigators rather than conclusions drawn from the initial reporting. No official determination of criminal or civil responsibility has been published in the sources reviewed.

For people working or travelling around central Brussels, the immediate consequences centre on the safety perimeter and access to the Treurenberg area. Authorities have not yet published a complete account of building damage, displacement or when normal access will resume.

The next authoritative update is expected from the Brussels emergency services, police or public prosecutor. Investigators will establish the ignition source, reconstruct the response to the leak and examine the circumstances in which the contractor struck the pipe. The identities of the firefighter and injured people should remain unpublished until the competent authorities confirm them and relatives have been informed.
