At least 14 people have been injured in Oklahoma after a strong storm knocked over the entrance trusses of an outdoor concert venue hosting 90's boy band favorites Backstreet Boys and 98 Degrees.
Officials urged awaiting fans to seek shelter, but about 150 people ignored the warnings and continued to wait in line.
Saturday's concert was eventually cancelled and the Backstreet Boys said they will attempt to reschedule.
Two out of the 14 sent to hospital, meanwhile, have reportedly been released.
