A moorland fire near an RAF base in North Yorkshire has been declared a major incident.
Crews were first called to Langdale Moor after reports of smoke on Monday and found the blaze had jumped a firebreak.
An overnight watch took place but by Tuesday morning, the fire covered 300 x 300m, growing to 1km x 1km by the afternoon.
Water bowsers, six fire engines and all-terrain vehicles were being used to fight the fire – near RAF Fylingdales – early on Wednesday.
North Yorkshire Fire Service said the blaze had shrunk overnight, but by 12.30pm it had spread to cover 5sq km and was declared a major incident.
Pictures posted on Facebook by Bedale fire station showed the fire burning overnight, while drone footage filmed on Tuesday showed huge flames and vast clouds of smoke.
More resources are now being sent to the scene in an effort to bring it under control.
The hot, dry weather in the UK has made such fires more likely and a fire on heathland in Dorset was also declared a major incident at the weekend.
Crews were still on site at Holt Heath today, dealing with hotspots and occasional flare-ups sparked by wind.
However, Dorset and Wiltshire Fire Service said “good progress” was being made across all four sectors of the incident.
