Foo Fighters, who were to headline, tweeted: "Our hearts go out to everyone affected by the tragic events at Pukkelpop."
Travis Barker who was supposed to play with Blink 182, tweeted: "Really sad bout Pukkelpop. Another stage collapses 2 dead & tons of people hurt. My heart goes out. Not supposed 2 happen at shows."
This is the third stage collapse to happen in this summer with Cheap Trick's stage at a festival in Canada and country music band Sugerlands stage collapsing just before they took to it at the Indiana State Fair.
