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.

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.

Human remains were found inside a fireworks' storage warehouse in rural Yolo County, officials announced on Friday, three days after a massive explosion occurred inside the facility.
