The China Mail - 'Unprecedented' fire rips through munitions site in Berlin forest

The fire began in the Grunewald forest in the early hours of the morning, with residents reporting a series of explosions.

Firefighters were initially unable to tackle the blaze directly due to the danger of further blasts, with emergency services setting up a 1,000-metre (3,280-foot) safety zone around the site.

Around 250 emergency personnel were deployed to the site.

The fire had spread across 50 hectares by the evening, according to police, but the emergency services were hoping to bring it under control overnight.

The most dangerous zones have been identified and firefighters have been cleared to proceed to within 500 metres of the blaze in some areas, they said.

The army had earlier sent in a tank aimed at evacuating munitions at the affected storage site as well as remote-controlled de-mining robots, while drones circled the air to assess the emergency.

- Heatwave -

Water cannons were also deployed around the safety zone to prevent the fire from spreading.

But authorities said no firefighting helicopters were available as they were already in use to tackle forest fires in eastern Germany.

They also said the 1,000-metre safety zone applied to the air, so there was a limit to how useful it would be to drop water on the fire from above.

Berlin mayor Franziska Giffey interrupted her holiday to visit the scene, calling the events "unprecedented in the post-war history of Berlin".

Giffey advised Berliners to close their windows but said the danger was minimal as there were no residential buildings within a two-kilometre (1.2-mile) radius and so no need to issue evacuation orders.

Road and rail traffic had been disrupted but was expected to return to normal in the course of the evening.

The fire came as a heatwave swept across Germany, with temperatures hitting 39 degrees Celsius (102 Fahrenheit) on Thursday.

Scientists say climate change is making heatwaves around the world more frequent and more intense, which increases the risk of fires.

Germany has suffered a series of forest fires this summer, with Brandenburg -- the state that surrounds Berlin -- among the hardest hit areas, along with the mountainous parts of Saxony state.

- Unexploded bombs -

Police said they were investigating what set off the fire in Grunewald.

The store holds munitions uncovered by police, but also unexploded World War II-era ordnance which is regularly dug up during construction works.

German media questioned the wisdom of having a bomb disposal site located in a major city.

"At least 25 tons of World War II ammunition and illegal fireworks were hoarded at the munitions site there, in the middle of the forest. How can this be?" Berlin newspaper BZ asked.

Cyclist Hellmut Schmidt, 64, who commutes through the forest to work, told AFP that "when you see all these fires, of course you worry".

"But I don't know where else you could have (a munitions site) in Berlin... If it was further from the city, then it would also be dangerous with the transport because something could explode," he said.

Giffey said local authorities would "have to think about how to deal with this munitions site in the future and whether such a place is the right one in Berlin".

Heavy thunderstorms are expected to sweep into the country from the west on Friday, the German weather service said.

A cold front is predicted to bring temperatures down by more than 10C overnight in western Germany, falling to around 20-25C on Friday.
