SAN JOSE – A major explosion at a pyrotechnics facility in Yolo County has forced the cancelation of a Fourth of July fireworks display at Lake Cunningham Park in San Jose, but a celebration will still take place, according to an city official.

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.

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.
