In pictures: Mississippi tornado devastates town

Images of devastation have emerged from Mississippi, where a tornado has killed at least 25 people.

The town of Rolling Fork, where 20% of residents live below the poverty line, was virtually flattened on Friday.

Rolling Fork Mayor Eldridge Walker told CNN: "My city is gone. Devastation - as I look from left to right, that's all I see."

The tornado overturned not just cars, but also homes.

US President Joe Biden called the images from Mississippi "heart-breaking" and ordered federal aid.

Search and rescue efforts are continuing in a community in shock.
