FRANKLIN, Tenn. (AP) — Police in Tennessee say eight children were taken to hospitals for evaluation after their church bus overturned on a highway during heavy rains.

News outlets report the bus with a driver and 11 passengers was returning from a conference in Chattanooga when the accident occurred Saturday along Interstate 840 south of Nashville.

According to the Tennessee Highway Patrol, the driver lost control and the bus struck a median and flipped on its side.

The children were from Bolivar's Parrans Chapel Baptist Church, which had borrowed the bus from a sister church. Parrans Chapel says in a statement the children were released after being evaluated.

The driver was not injured.

The accident remains under investigation.
