KINGMAN, Ariz. (AP) - The Mohave County Sheriff's Office says two people were killed and several others injured Sunday when their commercial tour bus drifted off an Arizona highway and rolled several times.
      
Sheriff's spokeswoman Trish Carter says the crash happened around 8 a.m. near Meadview, on the southeastern side of the Lake Mead National Recreation Area.
      
The bus was traveling with 11 passengers and a driver from Las Vegas to the west rim of the Grand Canyon.
      
Carter says several passengers suffered serious injuries and were flown to hospitals in Las Vegas and nearby Kingman.
      
The passengers' names were not immediately released. Carter says they may be tourists from another country.
