there. New terror threats surrounding the winter olympics and Brian Ross here with the latest. Good morning, Brian. Reporter: Good morning. The first test of the Russian approach to keeping the winter games safe as the olympic torch relay goes to the city of volgograd, the site of two deadly terror attacks just a few weeks ago including at the train station where the torch relay began this morning. All this as Russian security officials are dealing with a new threat from the very terror group responsible for those earlier attacks. This morning, U.S. Authorities studying this videotape of two alleged terrorists purported to be the suicide bombers who carried out the recent attacks. They were shown allegedly building their bomb, wiring themselves up detonator in hand and then heading to their targets. Their attacks included the volgograd train station and later a crowded trolley. In the tape the men said their group had more attacks planned. A surprise package, they called it, including one, they said, a surprise for the tourists who will come to sochi. In a separate online statement, the terror group said the volgograd attacks were only the beginning and said future threats could go as far as to include chemical attacks. The long and short of it, Vladimir Putin and the Russian government will belucky to get through without an attack. I would not go. And I don't think I would send my family. Reporter: But Russian authorities released their own video over the weekend showing a full-scale assault on a suspected militant stronghold in dagestan. Seven people were killed according to Russian officials who say their iron-fisted, take no prisoners approach will make the olympics safe. So far this morning the torch relay through volgograd has gone off without a hitch. ABC's kirit radio says the mood is festive despite a visible police presence which will continue as it moves to dagestan a stronghold of a terror group threatening the olympics. Thanks very much.
