Fire crew, who is struggling with a huge Murland Blaze in North Yorkshire, has said that they have been interrupted by exploding two bombs of world war and tank shells.
Emergency services are dealing with fire, which covers about 10 square miles (25 sq km) on Langdel Moore in North York Morse National Park from Monday 11 August.
County Chief Fire Officer Jonathan Dyson said the site had a tank training ground in the 1940s and over 18 explosions occurred as the fire was burnt through peat for already hidden explosives.
Mr. Dyson said that the fire service was considering the incident as a “important forest fire” and requested other services across England.
Mr. Dyson said that in some places the crew had to adopt a “very defensive fire -fighting strategy” due to unclear bombs.
“As the peat continues to burn down, this war is detecting the word two Ordnance and therefore exploding and we have now experienced more than 18 ordinance explosions within major areas.”
Mr. Dyson said that by the weekend he had made significant progress in managing and setting fire, but with changes due to wind and temperature, the blaze “had exceeded double in 24 hours”.
“Fire has spread rapidly in the north and northwest,” he said.
The crew teams were trying to reduce the spread and there were 10 tools committed to the operation with 60 firefighters, they explained.
“I have today requested national flexibility to deploy national assets to the region.”
Mr. Dyson said that help would consist of 10 equipment from other fire services across England and he was expected to come fast.
