German firefighters have put out most of the fire in the Grunewald forest that started after an explosion at a police ammunition depot.

This was reported by The Local.

Although most of the fires in Berlin's Grunewald forest have been extinguished, getting to the ammunition where the fire started remains a major problem.

Berlin Fire Service spokesman Thomas Kirstein said Friday that firefighters extinguished forest fires around the site of the explosions overnight.

"The fires were almost extinguished during the morning," Kirstein said, adding that smaller fires now remain. The fires have covered about 42 acres - about 100 soccer fields.

At the center of Friday's work is the blast site, around which police have set up a 1,000-meter radius safety perimeter because of the risk of further detonations. "We should expect detonations to continue," the fire department said.

Kirstein said the goal is now to get a more accurate picture of the situation at the blast site after the fire department, police and the Bundeswehr briefed on the situation in the morning.

An armored vehicle borrowed from the German Army will be used to drive up to the site and get first assessments.

In addition, the fire department has invited a fire tanker, which is used in explosive areas, from a private company. Three robots from Lower Saxony, which can extinguish the fire, are to drive up to the site of the explosion.

Kirstein stressed that this fire was a "very special situation and challenge" for the fire department.

The fire caused serious disruptions in Berlin's transportation network, with the main highway into the city from the south still closed Friday morning. The S7 line between Grunewald and Wannsee was also out of service Friday morning.
