At least 14 people have been killed and dozens injured in severe storms rolling across the US.
Vast swathes of Texas, Mississippi and Arkansas were struck by a strong line of storms that flattened homes, cut down power lines and knocked down trees.
Two people were killed by the storm in Mississippi, including a seven-year-old girl who died by electric shock and a two-year-old who was struck by a heavy, metal football goal post thrown by strong winds.
In Canton, a largely rural area 50 miles east of Dallas,Texas, search teams were seen going door to door after a tornado caused extensive damage.
"It is heartbreaking and upsetting to say the least," Canton mayor Lou Ann Everett said.
The destruction cut a path 35 miles long and five miles wide, Ms Everett said.
The National Weather Service found evidence of four tornadoes - with one twister possibly on the ground for 50 miles.
Four people are believed to have died in storm-related incidents in the state.
Two deaths were also reported in Missouri, including a woman who drowned after being swept away in a car.
In Arkansas, five people were killed by flooding and winds, including a fire chief who was struck by a vehicle while working on the storm and a 10-year-old girl who drowned in Springdale.
Meanwhile rescuers in north-west Arkansas continued to look for an 18-month-old girl and a four-year-old boy who were in a car swept off a bridge by flood water, the Madison County Sheriff's Office said.
