Authorities of the Republic of Georgia last year arrested a Russian man attempting to smuggle 100 grams of highly enriched - weapons grade - uranium into the country, according to a story by Lawrence Scott Sheets and William J. Broad of the New York Times.
The incident was discussed by Georgian Interior Minister Ivane Merabishvili in a recent interview. Russian officials would not comment on the story.
Another man was apprehended in 2003 at the Georgia-Armenia border with 170 grams of uranium. In neither case was the amount of radioactive material sufficient to build a nuclear weapon, but international authorities are concerned about the apparent trade in nuclear material from the former Soviet Union.
Georgian authorities also intercepted a shipment of 2.2 pounds of raw uranium last August.
