Poland has declared the region in which a Nazi "treasure train" was allegedly discovered to be a closed area.
Authorities say they are trying to "prevent accidents between people walking on nearby train tracks," though Polish media say that the government is trying to keep them away from the site.
Last month, two people claimed that they had discovered a train filled with precious stones and weapons, which had once belonged to the Nazis. The Polish government says that it is skeptical, but investigating.
