Aerial footage captured by a drone shows the devastation left by a tornado that struck a highway south of Mayflower, Arkansas.

At least 17 people were killed when a huge storm system swept across the central and southern United States.

Sixteen died in suburbs of Little Rock, the state capital and largest city in Arkansas, officials said.

This footage shows queues of vehicles on the debris-covered Interstate 40 on Sunday.
