Four dead and scores injured after dozens of tornadoes strike Oklahoma
At least four people have died, including a four-month-old baby, and scores have been injured in Oklahoma after dozens of twisters swept the southern plains of the United States.
Weather alerts put more than 7 million Americans under tornado warnings on Sunday.
Storm warnings for high winds, heavy rain and hail were issued by the National Weather Service (NWS) for more than 47 million people stretching from East Texas all the way up through the states of Illinois and Wisconsin.
The unsettled weather is forecast to continue across the mid-section of the country into Monday, the weather service said.
Oklahoma Governor Kevin Stitt declared a "disaster emergency" for the state, freeing up more money for first responders and recovery operations.
"You just can't believe the destruction," Mr Stitt said during a visit to the hard-hit town of Sulphur.
"It seems like every business downtown has been destroyed."
The NWS reported 38 possible twisters hit the area and that the worst of the storms rolled through Central Oklahoma on Saturday into early Sunday morning, spreading into north-west Texas, western Missouri and Kansas.
The deaths were reported by the Oklahoma Department of Emergency Management, with about 100 injuries reported in hospitals across the state.
Dozens of homes were destroyed or damaged.
The agency cautioned that the extent of the destruction was still being assessed, amid a mess of downed trees and power lines and debris-strewn roads.
