Crews are searching for survivors and surveying the damage after tornadoes and strong thunderstorms tore through Tennessee, overturning cars, ripping apart buildings and leaving at least six people dead.

At least three people died, including a child, after a tornado struck the Clarksville area of Montgomery County in northern Tennessee, officials said Saturday night.

Montgomery County was in a “search and rescue phase” Saturday evening after nearly two dozen people were treated for injuries at a hospital, officials said.

Footage obtained by CNN shows a tornado churning across a Clarksville road, flinging debris in the air and sparking power lines as it ripped through the area.
