After the forest fire broke out in the Lieberoser Heide in south-eastern Brandenburg, the fire brigade and police are also trying to contain the fire on the ammunition-loaded site on Tuesday.
Two federal police helicopters were to help fight the fire again in the morning, as a spokeswoman for the Dahme-Spreewald district said.
A helicopter extinguishes from the air, the second is equipped with a thermal imaging camera.
"The emergency services have the situation on site under control," said the district spokeswoman.
The wind has calmed down.
There is no danger for the population either.
An area of around 13 hectares has been on fire in Lusatia, north of Cottbus, since Monday evening.
According to the district, it is a bog area.
The emergency services cannot enter the area because it is loaded with ammunition.
At the end of June 2019, a fire raged on 100 hectares of the former military training area in the Lieberoser Heide.
Brandenburg has the largest proportion of munitions contaminated areas in Germany.
There are conversion areas - areas that are burdened by the withdrawal of Russian troops - as well as areas that were once used for military purposes.
Ordnance from the Second World War is still suspected on 350,000 hectares.Keywords:
