The explosion, which left seven people missing, started a wildfire and forced some cities and counties to cancel or postpone Fourth of July fireworks shows.

Authorities in northern California have confirmed the recovery of the bodies of seven people who had been reported missing following last week's explosion of a warehouse storing fireworks near Sacramento.

Seven people were "unaccounted for" in Yolo County's town of Esparto after several explosions at a fireworks warehouse resulted in a fire, officials said.
