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.

The girlfriend of one of three adult brothers who went missing in a fireworks factory explosion this week is speaking out, as she called the siblings 'three incredible men who had so much coming for them.

People were urged to avoid the area after the blast, which set off a barrage of fireworks and caused a massive blaze.
