The Tomorrowland music festival has kicked off in Belgium two days after a massive fire damaged its main stage. Workers cleared debris around the clock to ensure the event could proceed on Friday after the fire on Wednesday. Australian electronic music group Nervo opened the festival on the repaired stage, with some charred frames still visible. Organizers confirmed no injuries occurred and the cause of the fire is under investigation. Hundreds of thousands of people are expected to attend the annual festival, which is one of Europe's biggest summer music events.
