A state of emergency has been declared in Mississippi
The clean-up operation is continuing after a powerful tornado smashed through several southern US states.
At least 26 people have been killed, with dozens more injured, and hundreds displaced.
A state of emergency has been declared by US President Joe Biden, in the worst-effected state of Mississippi.
Sky's US correspondent Martha Kelner is in the town of Rolling Fork, which was in the direct path of the tornado:
"This was an extremely violent tornado, bringing winds of around 165-200 miles per hour, and in practice what that meant anything in its path was pulverised."
Courtney Ann Jackson, a journalist from Rolling Fork, Mississippi, says the destruction is off the scale:
"Rolling fork is already a small community. The businesses that they did have, have now mostly been levelled. Residents that we've talked with, they're trying to process things. We saw one woman with tears streaming down her face saying 'Thank Jesus I am still hear'."
