Berlin residents have been told to shut windows and doors after a large forest fire sent a giant plume of smoke across the city, with unexploded munitions from the second world war complicating firefighting efforts.

The blaze, which began on Thursday afternoon, spread quickly overnight to engulf 400 hectares (1,000 acres) of forest between the Brandenburg town of Treuenbrietzen and village of Jüterborg, 39 miles (63km) south-west of the German capital.

Flames lit up the forest as fire crews deployed water cannon and joined helicopters, army and police officers in an attempt to control the inferno.

A fire brigade spokesman told the newspaper Bild: “We can’t get to a lot of places, only the paths that have been cleared and are accessible.”
