California fireworks display collapse injures 28
At least 28 people were hurt when a California fireworks display collapsed, sending pyrotechnics into the crowd.
The closest of 10,000 attendees at an Independence Day celebration in Simi Valley were sitting 900ft (275m) away from the fireworks as they exploded.
Spectators fled as explosions shot along the ground after the wooden platform holding the display gave way.
Four people remain in hospital with serious but non-life threatening injuries, including a police officer.
Officials say they are still investigating the cause of the platform's collapse on Thursday evening, but there is no indication of foul play.
Simi Valley, the home of the Ronald Reagan Presidential Library, has held an Independence Day fireworks display for 43 years.
The pyrotechnics show has been run for the last two years by the same firm.
"There was a big boom. Everybody started running down the street. People were screaming," resident Justice Allen told the Los Angeles Times.
"Everybody was just terrified. People hid in bushes."
A police officer was left with a shrapnel tear through his clothing and minor injuries to his back.
Many people were treated for their injuries at a triage area set up in the park.
