A fire at the Oxy building in central Brussels has left six people missing, with authorities warning that several deaths are likely as access to the damaged site remains difficult.

Firefighters found multiple victims in a narrow opening inside an elevator shaft, raising the possibility that the total number of victims equals the missing persons or includes others elsewhere in the structure.

One person remains unaccounted for as search and rescue operations continue amid challenging conditions.

Officials at the highest levels raised the profile of the incident, with Brussels’ mayor, the prime minister, and the King visiting the area near Grand Place.

The Oxy tower is planned to host flats, a hotel, restaurants, and bars, situated in a densely built, central Brussels district.

Construction workers were evacuated and offered support at BruCity’s staff restaurant, with psychological aid provided by the Red Cross, coordinated by the city’s mayor.

King Philippe and Prime Minister Bart De Wever visited the site to thank firefighters and ambulance crews and to assess ongoing rescue efforts.

The incident is being covered in a brief video item with attribution to a news outlet, noting an ongoing fire service investigation.

Three workers were treated for injuries—two with burns and a firefighter with hyperthermia—while others were evacuated and received care, with further psychological support arranged.

Two additional patients were hospitalized with serious burns, and another firefighter received on-site treatment for high temperatures.

Emergency crews evacuated three workers from the building, including at least one burn victim transported to a hospital.

Initial reports indicate the fire began on the second floor and spread to the elevator shaft, with the blaze now under control.
