Tragedy has struck the concert world again. Less then a week after five people were killed when a stage collapsed at the Indiana State Fair, multiple casualties are being reported at a festival today in Belgium, where rock bands 30 Seconds to Mars, Good Charlotte, Foo Fighters and others were set to perform.

The stage collapsed during a brutal wind and rain storm as Chicago indie band Smith Westerns were about to take the stage on the first day of the annual Pukkelpop festival in the town of Hasselt, Belgium.

Alternative Press says that six people are reported dead by a Belgian media outlet. The exact number is in question, as the Associated Press reports three dead with 71 others injured, while 30 Seconds to Mars singer Jared Leto tweeted, "Two confirmed dead. 40 at the hospital. Sending our thoughts and prayers."

The three-day fest was canceled for the remainder of the day, but it's unclear whether the event will resume on Friday, when Eminem is the scheduled headliner. PopCrush will continue to report the details on this tragic story as more information becomes available.
