28 injured at Calif. fireworks when platform tips

More than two dozen people were injured when a wood platform holding live fireworks tipped over, sending the pyrotechnics into a crowd at a Fourth of July show northwest of Los Angeles.

Between 8,000 and 10,000 revelers were settling into their seats for the fireworks extravaganza at a Simi Valley park Thursday night when the fireworks exploded on the ground.

Twenty-eight people were injured. Four people were listed in serious condition, but their injuries were not considered life-threatening. Sixteen more were taken to hospitals with minor to moderate injuries. The remainder were treated at the park where emergency crews set up a triage area.

Police are still investigating what led to the explosion, but they said early indications show a platform designed and built to hold the fireworks gave way.
