SIMI VALLEY, Calif. - An accidental explosion last night at a California fireworks show injured more than 30 people, four of them seriously, officials say.
The explosion happened at an annual Fourth of July fireworks display at a Simi Valley park, not far from Los Angeles. A platform holding the fireworks gave way, sending the pyrotechnics into the crowd as thousands of people looked on.
The victims ranged from 8 years old to 78, police say. A total of 20 people were taken by ambulance to area hospitals. Four suffered serious, but not life-threatening, injuries.
The show was staged by a Long Island-based company, Bay Fireworks. The company said in a statement that it regrets the injuries and plans a thorough investigation, with results to be made public.
Bay Fireworks has produced events for NASA, Walt Disney World, Legoland and the Republican National Convention, according to the company's website.
