SIOUX CITY, Iowa (AP) – Fire department officials in Sioux City say they’re investigating what started a small fire at a feed plant.  KTIV-TV reports someone called authorities early Tuesday and reported seeing smoke near the Hubbard Feeds, Inc. plant in Sioux City.

Assistant Fire Chief Brad Robinson says crews found a small, smoldering fire had broken out in the facility’s cooling tower down in the basement.  Robinson says the fire was extinguished and damage was confined to one cooling box of feed pellets.
