A state official says two people are dead and 21 injured after a tour bus ran off a southern Minnesota interstate and rolled over in a ditch.

Minnesota Department of Public Safety spokesman Andy Skoogman confirms the deaths from the crash that happened about 3:30 p.m. Wednesday on Interstate 90 west of Austin.

Authorities earlier said as many as 22 people were hurt in the crash.

The Post-Bulletin of Rochester identified the bus as operated by Strain Bus Line Motorcoach Tours in Rochester. An employee who answered the phone at Strain would not give her name, but said the owner was on his way to the scene.

The employee told The Associated Press the company operates a bus every Wednesday from Rochester to Diamond Jo Casino in Northwood, Iowa.
