Seven people remain unaccounted for days after multiple explosions obliterated a fireworks facility Tuesday in the Esparto area of Yolo County, Cal Fire said. The explosions and fire that followed caused nearby evacuations and power outages.

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.

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