Sixteen people have been killed after deadly tornadoes ripped through southern America, flattening homes and destroying neighbourhoods.

Forecasters have warned that more storms and hurricane-force winds are due on Saturday night, as thousands of people were left without power.

Ten people were killed in Missouri, officials said, after twisters tore through the state.

One man died after a tornado passed straight through his house.

“It was unrecognisable as a home. Just a debris field,” said Coroner Jim Akers of Butler County.

“The floor was upside down. We were walking on walls”, he said, adding that emergency responders managed to save one woman from the property.
