BIRMINGHAM, Ala. — A state corrections official says a reported tornado in northern Alabama hit a state prison but there was no immediate word on damages or injuries.

Corrections spokesman Brian Corbette said today a tornado hit the Limestone Correctional Facility, a prison in Limestone County.

Another reported tornado destroyed several houses in northern Alabama as storms threatened more twisters across the region, two days after a storm system killed 13 people in the Midwest and South.
