WARSAW, Poland (AP) — A Polish official says he has seen images made by ground-penetrating radar that seem to prove the discovery of an armored Nazi train missing in southwestern Poland since World War II.

Local lore says a German train filled with gold, gems and armaments went missing around the city of Walbrzych while it was fleeing the Red Army in 1945. Fortune-hunters have looked for the so-called "gold train" for decades, and in the communist era, the Polish army and security services carried out apparently fruitless searches for it.

Recently two men said they found the train in a disused tunnel.

Deputy Culture Minister Piotr Zuchowski called it an "exceptional" discovery and said the train could contain valuables.

He said he was "more than 99 percent certain that this train exists."
