Polish military personnel on September 4 began inspecting and photographing the site where authorities suspect a Nazi-era train, possibly carrying guns and looted jewels, may be buried. Two amateur treasure hunters, a German and a Pole, said in August they had found the train, and said it should be exhumed and displayed as a tourist attraction. REUTERS/Piotr Hawalej
