A pensioner in Germany claims to have found evidence of Nazi nuclear bombs hidden underground.

Peter Lohr, a 70-year-old amateur historian, said he found traces of mysterious metallic objects in a long-abandoned network of tunnels built by the Nazis near the city of Chemnitz.

“At least two of the objects are the Nazi atomic bombs,” he told Bild newspaper.

Amateur historians and treasure hunters have long sought artefacts which disappeared during the Second World War, including the fabled Amber Room and the gold train rumoured to have been found in Poland last year.
