SOCHI, Russia -- Russian security officials are hunting down three potential female suicide bombers, one of whom is believed to be in Sochi, where the Winter Olympics will begin next month. Adidas Garth Snow Jersey . Police leaflets seen by an Associated Press reporter at a central Sochi hotel on Tuesday contain warnings about three potential suicide bombers. A police letter said that one of them, Ruzanna Ibragimova, a 22-year-old widow of an Islamic militant, was at large in Sochi. A U.S. congressman who was in Sochi on Tuesday to assess the situation said he was impressed by the work of Russian security forces but troubled that potential suicide bombers had gotten into the city, despite all of the extraordinary security measures. "We know some of them got through the perimeter," Rep. Michael McCaul, chairman of the U.S. House Homeland Security Committee, told The Associated Press. "Shes for real. What we dont know is how many more black widows are out there." Russian authorities have blamed the so-called "black widows" of slain insurgents for previous suicide attacks in the country. The Black Sea resort town will host the games amid concerns about security and potential terrorist attacks. The southern city of Volgograd was rocked by two suicide bombings in late December, which killed 34 and injured scores more. An Islamic militant group in Dagestan posted a video on Sunday claiming responsibility for the bombings and threatened to strike the games in Sochi, about 500 kilometres (300 miles) west of Dagestan. McCaul, a Republican from Texas, said he had numerous meetings with officials in Moscow and Sochi, and was briefed by the joint operation centre in Sochi, which is responsible for overall security in the area. "The one improvement I would ask of the Russians is to allow our intelligence services to co-ordinate and co-operate better with theirs," McCaul said. Although the Russian side was confident that it could provide security, the U.S. has information that could help keep the games safe, he said. The congressman also expressed concern that terrorists could have gotten into Sochi before security was tightened. "How many potential cells could be in Sochi and the Olympic village?" he said. "But after the ring of steel was implemented we have this one person who seems to have been able to penetrate it. It does demonstrate vulnerability." Police material distributed to the hotel staff included pictures of two other women in veils: 26-year-old Zaira Aliyeva and 34-year-old Dzhannet Tsakhayeva. It said they had been trained "to perpetrate acts of terrorism." It warned that the two women "are probably among us," but, unlike Ibragimovas case, did not say if they are in Sochi. No further information was provided about the two women or their motivation. The term "black widow" refers to the belief that women who have carried out past suicide attacks in Russia did so to avenge the deaths of husbands or other male relatives. Security officials in Sochi were not available for comment on Tuesday. The Olympics are to be held Feb. 7-23. Russia has mounted an intense security operation in the city, but concern persists that "soft targets" outside the Olympic venues, such as buses and tourist facilities, are vulnerable to attack. Russian troops also have been active fighting militants in Dagestan, one of the predominantly Muslim republics in Russias North Caucasus and the centre of an Islamic insurgency that has engulfed the region. On Tuesday, troops shot dead the leader of a militant group, Interior Ministry spokeswoman Fatina Ubaidatova said. She said the militant, Eldar Magatov, was wanted in attacks on security forces, bombings and the extortion of businessmen. Interior Ministry troops elsewhere in Dagestan defused an explosive device placed near a village administration building and engaged in a firefight with militants holed up in a house, the spokeswoman said.

The former NHL MVP is still being paid by the Flyers through 2017, even though he hasnt played in the league since 2011 due to concussions and an eye injury.Bettman wouldnt confirm Pronger is a candidate for a job in the player safety department, noting several candidates are interviewing for the job to replace Brian Leetch.Chris case is unique, Bettman said. There are salary cap reasons why he couldnt officially retire, but ... if in fact we go that route, Im not sure that presents any problem at all to deal with. Hes done playing. He gets paid no matter what from the Flyers. He doesnt owe them anything.Quintals department is responsible for doling out suspensions, fines and other discipline for on-ice transgressions, traditionally one of the NHLs most contentious areas. Pronger ran afoul of the office many times during his bruising career, incurring numerous suspensions for vicious hits and questionable on-ice behaviour.Pronger has an annual cap hit around $4. Bob Nystrom Jersey. 9 million for the Flyers, who signed him to a seven-year contract extension in 2009 after acquiring him in a trade with Anaheim.Pronger played in just 145 regular-season games for Philadelphia, but the Flyers would incur serious salary-cap consequences if he retired, likely forcing the club to trade players to get under the limit.With relatively little controversy in NHL circles heading into the new season, Bettman relished the opportunity to enjoy the pregame banner ceremony and a rivalry game at Staples Center between Los Angeles and San Jose.He also expressed admiration at the NBAs enormous television rights deals with ESPN and TNT. The new arrangement will increase the leagues annual TV revenue from $930 million to more than $2.6 billion.The NHL reached a 12-year, $4.9 billion Canadian rights deal last November, and the league reportedly makes about $200 million annually on its U.S. deal with NBC Sports through 2021.At the time, people were hailing it as a terrific deal, Bettman said. We more than doubled our rights, and based on whats happening to the marketplace, the next time we go into the marketplace, Im sure well do quite well. ... Ive always said to the owners, If we get to the end of our deal and were being underpaid, thats a really good thing.Bettman doesnt regret inking a long-term deal with NBC, and he doesnt worry that the U.S. sports rights market will deflate in the next seven seasons.People have been saying theres a sports bubble for the last 40 years, Bettman said.
