At least one person has died and several others were injured in a series of tornadoes that have torn through the US state of Oklahoma.
The worst damage was caused by a tornado near the town of Shawnee, 35 miles (55km) from Oklahoma City.
Twisters, hail and high winds also hit Iowa and Kansas, part of a storm system stretching from Texas to Minnesota.
