Malfunctioning fireworks veered into the stands at a crowded US football stadium and struck members of the audience during a Fourth of July celebration, sending up to six people to hospital, according to authorities and the event organiser.

The accident occurred during the opening ceremonies of the Stadium of Fire show, the flagship event at Provo’s annual Freedom Festival at LaVell Edwards Stadium, Brigham Young University in Utah.
