Tornadoes have torn through parts of the American South and Mid West, killing at least 10 people, shredding homes and shopping centres and collapsed the roof of a theatre during a concert.

Emergency responders across the region counted the dead and surveyed the damage on Saturday morning after tornadoes touched down into the night, part of a sprawling storm system that also brought wildfires to the southern Plains and blizzard conditions to the Upper Mid West.

The dead included four in the small town of Wynne, Arkansas, Cross County Coroner Eli Long told KAIT-TV. Other deaths were reported in Alabama, Illinois, Indiana and the Little Rock area of Arkansas.

Wynne City councillor Lisa Powell Carter said the town about 50 miles west of Memphis, Tennessee, was without power and roads were full of debris.

The storms also killed three people in Sullivan County, Indiana, emergency management director Jim Pirtle said in an email. Some residents were missing in the county seat of Sullivan, near the Illinois border about 95 miles south west of Indianapolis.

At least one person was killed and more than two dozen hurt, some critically, in the Little Rock area, authorities said.

Fire Chief Shawn Schadle said 260 people were in the venue. Responders also rescued someone from a lift and had to deal with downed power lines outside the theatre.

Police Chief Shane Woody described the scene after the collapse as “chaos, absolute chaos”.

A tornado also killed a woman and critically injured three other people in Madison County, Alabama, emergency services worker Don Webster told WAFF-TV.

The tornado in Little Rock tore first through neighbourhoods in the western part of the Arkansas capital and shredded a small shopping centre. It then crossed the Arkansas River into North Little Rock and surrounding cities, where widespread damage was reported to homes, businesses and vehicles.

In the evening, officials in Pulaski County announced a confirmed fatality in North Little Rock.
