MONTICELLO — Six people aboard an Air Force Reserve bus were hurt when a semitrailer collided with the bus on Interstate 94 in central Minnesota.

Spokesman Paul Zadach  with the 934th Air Lift Wing in Minneapolis says the bus was on its way to a training site near Fargo, North Dakota, when the semi apparently rear-ended it around noon Thursday near Monticello.

Zadach says six of the 13 people aboard the bus were hurt. The State Patrol says most of the injuries don’t appear to be life-threatening, but one person suffered serious injuries. The semi driver had minor injuries.

The patrol says the bus was stopped in traffic when the semi hit it. The bus rolled and struck two other vehicles. Traffic became backed up but has since cleared up.
