People on at least six floors of the Harrah’s Council Bluffs hotel/casino were evacuated early this (Wednesday) morning, when a fire erupted in the kitchen on the 12th-floor of the restaurant. The Omaha World-Herald reports thick smoked filled at least two floors of the casino on the western edge of the city, and a light haze drifted through other floors. Authorities said a 24-year-old security guard at the hotel was taken to Mercy Hospital for treatment of smoke inhalation.
