A new wildfire has broken out near Russia’s main nuclear research facility at Sarov.
It’s the second time the top secret centre has come under threat and firefighters have once again been deployed.
Meanwhile, concerns remain over the areas bordering Ukraine and Belarus, where the soil is still contaminated by the 1986 Chernobyl disaster.
The director of Russia’s Forestry Institute, Andrei Sirin said there was no reason to panic but that these forest regions needed special protection from fires, because a radioactive cloud could rise along with the smoke, and spread.
Although the total area ablaze in central Russia has fallen by half since Tuesday, the Emergencies Ministry says hundreds of wildfires are still burning.
Locals have joined some 165,000 firefighters battling the blazes.
