At least one person has been killed and several injured in a series of tornadoes that have torn through the US state of Oklahoma.
The storm flattened a mobile home park near the town of Shawnee, while trees were shredded and other homes destroyed.
Residents reported downed power lines lying on roads.
Twisters have been reported in other states, including Iowa, Minnesota, Kansas and Illinois.
The National Weather Service (NWS) warned of a dangerous tornado approaching the city of Wichita, Kansas. It had earlier issued urgent appeals for people in parts of Oklahoma to take cover.
