ST. PAUL, Minn. (AP) — No serious injuries are reported after a school bus carrying 20 students crashed into parked cars and nearly struck a post office in St. Paul.

Police spokesman Steve Linders says the crash happened around 8 a.m. Monday.

Linders says an 8-year-old and a 10-year-old on the bus and an adult aide were taken to a hospital after complaining of aches and pains.

The cause of the crash remains under investigation, but Linders says drugs and alcohol do not appear to be factors. The bus driver stayed on the scene and is cooperating with authorities.

The bus was taking children to the West Side Summit Charter School when it sideswiped three cars, jumped a curb and careened toward the post office building.
