At least two people are dead and 21 are injured after a tour bus ran off a southern Minnesota interstate and rolled over in a ditch, officials said.

Minnesota Department of Public Safety spokesman Andy Skoogman has confirmed the deaths from the crash that happened about 3:30 p.m. today just two miles west of Austin on Interstate 90.

Sgt. Jackie Sticha of the Minnesota State Patrol said the bus operated by Strain Bus Line Motorcoach Tours in Rochester was traveling east at about 3:20 p.m. when it crossed into westbound lanes and crashed.

Strain Bus Line operates a bus every Wednesday from Rochester to Diamond Jo Casino in Northwood, Iowa.

The patrol said the road was clear and dry.
