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.

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

The fiery blast occurred at a Yolo County property used by Devastating Pyrotechnics, a company known for staging large-scale fireworks displays.
