Minnesota State Patrol and other emergency responders are at the scene of a crash at a K-12 school in far south-central Minnesota.

Mower County Sheriff’s investigators say several were injured when a semi truck hit the building and broke through a wall into the school at around 9:00 a.m. The exact number of injuries and whether any students were hurt is not known.

The school is about an hour south of Owatonna along Highway 21, near the Minnesota-Iowa border.
