One firefighter suffered minor injuries and an apartment resident had to be rescued from a five-alarm fire Sunday morning in Genoa City.
The fire displaced 12 people, including three children.
Officials say dozens of firefighters from several departments responded.
The injured firefighter fell through a floor but was able to walk out of the building on his own power.
Investigators say the fire appears to be accidental.
At least six oxygen tanks exploded inside one apartment unit.
