A deadly fireworks explosion in Yolo County has disrupted Fourth of July celebrations across Northern California, prompting a wave of cancellations and postponements from Chico to the Bay Area.

SACRAMENTO, Calif. (AP) — Rescue crews were searching on Thursday for seven people still missing days after an explosion at a fireworks warehouse in Northern California shook a tiny farming community and forced the cancellation of nearby July Fourth celebrations.

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