Seven people are missing following a huge fireworks warehouse explosion in California. A blaze broke out at the storage facility in Yolo, 40 miles outside of Sacramento, Tuesday, erupting into a huge fireball. Aerial footage from the scene showed large plumes of black smoke spreading across the surrounding farmland.

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.
