About 200 firefighters are tackling a very large fire which is spreading rapidly across heathland in Dorset, putting homes at risk.

Strong winds are causing the fire, on about three sq km (740 acres) of Upton Heath, Poole, to quickly spread.

Eyewitness Steve Davis of Dorset Wildlife Trust described the impact and extent of the blaze.
