Seven people were "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.

H uman remains have been found at the warehouse filled with fireworks that exploded in Northern California this week, officials said. The number of fatalities was not released and no positive identifications have been made, Yolo County officials said. Seven people were considered missing on Wednesday.
