A huge fire on Wednesday at Belgium's Tomorrowland music festival site has “severely damaged” the main stage two days before the event was due to start, organizers said.

A day before crowds were set to arrive for the Tomorrowland festival in Belgium, a fire broke out and severely damaged its iconic main stage. The incident occurred in the town of Boom, near Antwerp, just as final preparations were underway.

A day before Tomorrowland was set to kick off on Thursday, videos of the fest’s main stage engulfed by flames began circulating online. The festival’s official website and Instagram released an official statement confirming the “serious incident and fire,” adding that the event’s “beloved Mainstage has been severely damaged.”
