According to the BBC, 19 were injured and one woman died when "temporary scaffolding outside Green Point stadium came down in high winds just before the concert."
Linkin Park performed, not knowing about what had happened until they had finished their set.
"We wish to express our deep sadness and concern for those injured and our heartfelt condolences to the family of the fan who died as a result of her injuries," the band wrote in a Facebook post. In the post, the group blamed the accident on "the collapse of an advertising tower erected by Lucozade in the parking area outside the venue."
"Though we have had no relationship with the sponsor or the entity responsible for erecting the structure," the post concluded, "we take the safety of our fans very seriously and our thoughts are with all of those who were affected by this tragedy."
Sadly, this is not the only time recently that a concert was the setting for an accidental death. Over the summer, Radiohead cancelled a Toronto show at Downsview Park after one of their technicians, Scott Johnson, was killed due to a pre-show accident.
At this time, it's unclear how severe the injuries were to the other 19 victims, although the BBC is reporting that 12 of them were taken to the hospital.
