Moment firefighters capture rare 'dust devil' as they battled a huge heath blaze

A rare 'dust devil' was captured on camera by crews battling a massive wildfire at Holt Heath near Wimborne. The whirlwind of dirt, typically seen in deserts or arid areas, was spotted as firefighters fought to control the blaze, which has scorched 170 acres of heathland. While dust devils are usually harmless, they can pose a danger if they grow too large.
