Several bodies have been found in an elevator after a fire in an office building under construction in central Brussels, local media reports said on Tuesday.
The Brussels Prosecutor’s Office said that six people had been reported missing in the fire.
The exact number of fatalities was not clear, it added.
Some 250 workers were at the site when the fire broke out on Tuesday.
A fire department spokesman told dpa that firefighters had been dispatched to a small fire on the second floor of the building.
