with a new and urgent warning about security at the olympics. 17 days away. And sochi, Russia, authorities now on the hunt for these eyes, this face. A young woman thought to be what they call a black widow terrorist, on a suicide mission. And the fear, tonight, she is already on the ground, where American athletes and fans from around the world will descend. We have the latest right now, tonight, from ABC's chief investigative correspondent, Brian Ross. Reporter: Authorities believe the young woman arrived in the sochi area about a week ago. Somehow making it past the ring of security set up to protect the olympic games. Over the weekend, police distributed this wanted poster to hotels and at the airport, for a so-called black widow terrorist. She was identified as 22-year-old ruzanna ibragemova, of dagestan, whose husband was killed in a shoot-out with police last year. The young woman was described as having a four-inch facial scar, a pronounced limp and a left arm that would not bend at the elbow. And security experts say, she is not likely to be traveling alone. When it's women, they tend to operate in teams of two. And it's very unlikely they would just send one of these teams into sochi. Reporter: Some 80,000 security personnel have been sent to sochi to create what Russian president Putin calls a ring of steel, about 60 miles long and 25 miles wide. Putin told George stephanopoulos, that will keep the winter games safe. Translator: We will do whatever it takes. Reporter: Over the weekend, the group that took credit for the two recent bomb attacks in the Russian city of volgograd, 400 miles from sochi, released this video purporting to show the two suicide bombers responsible, building their bombs, wiring themselves up and then traveling to their targets. Dressed in casual street clothes, the two men said their group had more of what they called surprise packages for sochi and for the tourists who will attend. Now, one U.S. Senator says, it's just too dangerous to go. I would not go. And I don't think I would send my family. Reporter: The threats to the olympics can be traced back to a decades-long and bloody conflict, between Russia and islamist militants in chechnya and dagestan, who seem to break away from Russia's rule. The people we see are the suicide bombers we see in the news now, these are the people who have grown up over the last 20 years with nothing but the legacy of that war. Reporter: And the black widow attacks have been especially deadly. Almost 200 people killed by them in suicide attacks in the last dozen years or so, Diane. Tell me more about what the U.S. Is doing with these warnings coming in? Reporter: There will be small teams of armed U.S. Personnel assigned to watch over athletes. As well, the Pentagon said today, they made contingency plans to get Americans out of there in a hurry, if they have to, including two U.S. Navy ships that will be on scheduled deployment on the nearby black sea. Thank you, Brian. And our next big story in
