The cause of the blaze remains unknown.

A massive fire severely damaged the main stage at Belgium’s Tomorrowland, one of the world’s largest electronic dance music festivals, just days before its scheduled opening.

The blaze erupted Wednesday at the festival grounds in Boom, Belgium, where thick plumes of black smoke could be seen rising into the air. Video footage shared on social media showed large flames engulfing the main stage, along with what sounded like fireworks going off.
