Seven people are missing after a warehouse holding fireworks caught fire and set off a series of massive explosions in Northern California late Tuesday.

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

One family told KCRA 3 that three brothers from the Bay Area work at the warehouse and haven't been heard from since Tuesday afternoon. They showed up at the roadblock just before noon Wednesday looking for information.
