A blaze turned into a tornado-like whirl as firefighters worked to extinguish a fire at a plastics factory in Derbyshire, England.

The "firenado" swept across the fields near the factory, as the fire sent dark plumes of smoke into the sky on Monday.

The Leicestershire Fire and Rescue Service posted footage online, saying: "Whist we were firefighting at Occupational Lane we witnessed a firenado or a fire whirl", which is "created as cool air enters the top of the hot air causing a swirl similar to how a tornado is formed".
