ROY, Utah (AP) Authorities say an accident at a fireworks show in northern Utah injured 10 people.
Fire officials say the spectators at the annual Roy Days festival all escaped with minor injuries after an unexpected sideways fireworks blast just after the show's finale.
Roy Fire Chief Jason Poulsen told the Standard-Examiner of Ogden says all 10 victims were treated at the scene and included both children and adults.
He says the show was operated in line with required safety standards and the fireworks malfunction could not have been predicted.
He says an earlier firework caused a small grass fire but it was put out by crews while the show continued.
