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. 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.

Nike Air Max Uk Sale Outlet . -- Patrick Kueng of Switzerland was nearly flawless as he captured his first World Cup and halted Aksel Lund Svindals streak of four straight super-G victories on Saturday.Weve had a couple days to sit back and reflect on Toronto FCs first setback of the early season. Neither the performance, nor the scoreline flatters in the 3-0 loss at Real Salt Lake Saturday. It was always going to be a difficult match against MLS Cup runners-up and a team with minimal roster change year over year. Certain flaws were exposed and much work remains for a team in transition. On the surface, a 3-0 loss to the casual fan or someone who didnt see Saturdays match may suggest, ‘same old TFC. Thats hardly the case. TFC has experienced its fair share of lopsided results in recent years with the vast majority reflective of a lack of quality and the gulf in talent that existed between competitors. Saturdays loss was more about Real Salt Lake taking advantage of TFC mistakes than any lopsided pedigree between rosters. Team cohesion and familiarity also skewed in favour of the home side. And even while on the back-foot for most of their visit to Rio Tinto, Toronto remained dangerous to the end and is certainly no longer a team you can take a lead against and rest on your laurels. Theres no reason to lose excitement about what this team can be based upon this one performance alone. However, lessons were learned and improvement is required. Here are five thoughts on Toronto FCs loss at Real Salt Lake. 1. Jermain Problem Striker Jermain Defoe left the match in the 62nd minute and headed straight to the locker room, clutching his hamstring. Gulp. Head Coach Ryan Nelsen commented post-match, “He was feeling the hamstring before the game and it tightened up.” Defoe had a ‘slight hamstring issue at Tottenham before joining Toronto FC. The severity of Defoes most recent potential setback has not been revealed. Regardless of the severity, Toronto FC must proceed with caution. Hamstrings are tricky and, if not dealt with appropriately, can linger and lead to extended spells on the sidelines. The extensive travel and varying playing surfaces across Major League Soccer put exceptional wear and tear on the body. Durability is key for Defoe and it will take time to adjust to the conditions of North American football. The team needs a healthy Defoe to be considered among MLS elite. The pre-season injury loss of Bright Dike complicates matters more, leaving TFC all-too thin up front. So the inclination will be to play Defoe as soon as hes deemed relatively fit. Theres no need to play hero and play through the injury. The season is a marathon. The long view must be the priority with TFCs prized possession. 2. Difficult Night for Doneil Centre back Doneil Henry was among TFCs top players in the first two games. The 20-year old has all the qualities to be a top defender in MLS, but Saturday was tough for him and his partner in the middle of the back four, Steven Caldwell. Henry was the culprit for the penalty leading to RSLs opening goal. A harmless, lazy ball was played to the feet of RSL striker Alvaro Saborio at the top corner of the 18; an innocent one-vs-one situation with the attackers back to goal. Instead of taking a step back and focusing on position, Henry came through the back of the player with his arms wrapped around Saborio trying to get to the ball. The striker went to the ground, making for an easy point to the penalty spot for match official Baldomero Toledo. It was an unnecessary, sloppy challenge from Henry, showing shades of last season when he had the unbecoming habit of diving in and/or over-committing to challenges at inopportune times in vulnerable areas. The time, place and execution of this challenge gone wrong was all amiss. Theres much to like about Henrys commitment, aggressiveness and enthusiasm, but he has to pick his spots. Henry has the athleticism to cover a lot of ground, meaning he can afford to take an extra step back and gain superior position while still being aggressive in challenges. Superior defensive positioning and proper decision-making will come with furtheer maturity, experience and direction.dddddddddddd Henry will be just fine and a key cog in this Toronto FC team. Mistakes like this are part of the process a young player goes through. 3. Flaws in Defensive Execution High pressure can be a teams best and worst enemy. Nelsens team has shown the desire and commitment to put all kinds of pressure on the ball, all over the field. Its often a high risk, high reward proposition, but can leave a team vulnerable if a solid defensive shape doesnt hold true. Toronto FC lost its defensive balance against a crafty Real Salt Lake midfield diamond that regularly found space between TFCs centre midfield duo and the backline. Javier Morales at the top of the diamond found freedom in the gaps, leaving Torontos defenders not knowing whether to step forward and commit or fall back to cover. Nelsens 4-4-2 isnt to blame for the breakdown, though - the problem was in execution. If Toronto FC is going to continue to put constant high pressure on the ball, the centre backs need to keep the formation compact to condense the space and provide more support to the centre midfielders. When Michael Bradley commits to the pressure on the ball, the space behind needs to be limited. Of concern for Nelsen, as he tries to get his team working in unison, is a speed deficiency at certain defensive positions. If the defenders arent confident they can make up ground, leaving space in behind, the tactical formation will fall apart. The hope is superior execution of high pressure defensive play will come in time, as this new-look roster grows accustomed to tendencies and the strengths and weaknesses of their new teammates. 4. Jackson Leaves a Hole It came as somewhat of a surprise that Mark Bloom, starting right back in Torontos first two wins, moved forward to play outside right midfield with Jackson suspended. Bradley Orr slotted in at right back, which seems to be the longer term plan once the Englishman finds full fitness. Bloom did a nice job as an outside defender to start the season, but an outside midfielder, he is not. It speaks to the lack of depth at the position that Nelsen chose to deputize Bloom at it. Right midfielder Issey Nakajima-Farran made his MLS debut as a 59th-minute substitute. Whether hes suited for this league and can be effective is still to be determined, but based upon TFCs lack of options, hell get every look possible. TFC cannot afford to continually have a fullback playing a forward position. It wasnt as if Nakajima-Farrans introduction that led to Toronto FC having success down the flanks. It was more the fullbacks pushing forward than influence from the outside of the midfield. Regardless, proper role definition leads to a level of comfort and greater fluidity. The team will have to find more depth at the wing positions or consistent build up will be sacrificed. 5. Keep the Ball! To nobodys surprise, Real Salt Lake dominated in possession, managing 63 per cent of the ball in the contest. This marks the third straight week TFC have been short in possession. TFC may never be a dominant ball possession team, able to boss the proceedings, but they have to be much better. Poor field conditions and inconsistent surfaces, combined with unfamiliarity with new teammates are certainly excuses, but its too many long balls out of the back and not enough service to the feet of the strikers that are ultimately responsible. Defoe, Gilberto and Dwayne De Rosario are forward players who demand the ball at their feet. Having the trio chase down searching balls, while regularly competing in aerial battles, is a waste and hardly how to get the most out of the talent. It starts at the back, but the build through the midfield has a ways to go. This is a work in progress. Keeping the ball and playing along the ground with quality is paramount in the growth of the team. Toronto FC is next in action on Saturday when it the visits the Columbus Crew.
