MOSCOW -- Russias counter-terrorism agency says its studying a video posted by an Islamic militant group that asserted responsibility for suicide bombings that killed 34 people last month and is threatening to strike the Winter Olympics in Sochi. Security experts say the Russians are right in taking the threat seriously. The video was posted online Sunday by a militant group in Dagestan, a predominantly Muslim republic in Russias volatile North Caucasus. The Olympic host city of Sochi lies only 500 kilometres (300 miles) west of Dagestan. Two Russian-speaking men featured in the video are identified as members of Ansar al-Sunna, the name of a Jihadist group operating in Iraq. It was unclear whether the men in the video had received funding or training from that group or only adopted its name. There was no confirmation the two men were the suicide bombers who struck the southern Russian city of Volgograd last month as the video claims. Scores of people were also injured by the bombings of a train station and a bus. Russias National Anti-Terrorism Committee said Monday it was studying the video and would have no immediate comment. The video couldnt be viewed in Russia, where Internet providers cut access to it under a law that bans the "dissemination of extremist materials." It was released by the Vilayat Dagestan, one of the units that make up the so-called Caucasus Emirate, an umbrella group for the rebels seeking to establish an independent Islamic state in the North Caucasus. Doku Umarov, a Chechen warlord who leads the Emirate, had ordered a halt to attacks on civilian targets in 2012. But he rescinded that order in July, urging his followers to strike the Sochi Olympics, which he denounced as "satanic dances on the bones of our ancestors." The games run from Feb. 7-23. The Kremlin-backed leader of Chechnya claimed last week that Umarov was dead, but the claim couldnt be verified. The Vilayat Dagestan statement said the Volgograd attacks were carried out in part because of Umarovs order, but it didnt specifically say he had ordered them. Dagestan has become the centre of an Islamic insurgency that has engulfed Russias North Caucasus after two separatist wars in Chechnya. Militants seeking to create an independent state governed by Islamic Shariah law in the Caucasus launch daily attacks on police and other authorities there. One of the two ethnic Chechen brothers accused of staging the Boston Marathon bombings spent six months in Dagestan in 2012. Andrei Soldatov, an independent Moscow-based security analyst, said the video threat need to be taken seriously. "They have capabilities to strike beyond the North Caucasus, which they demonstrated in Volgograd," he said. "Its extremely difficult to stop a lone wolf suicide bombing attack." Georgy Mirsky, a respected Russian expert on the Middle East, said the video reflected the increasingly close ties between Jihadists in the Caucasus and elsewhere. Russias war against Caucasus militants has made it an enemy on par with the United States and Israel for militant Islamic groups in the Middle East, he wrote on his blog. Russia has responded to the Islamic threat by introducing some of the most sweeping security measures ever seen at an international sports event. Some 100,000 police, army and other security forces have been deployed, according to analysts, and tight restrictions have been placed on access to the Sochi area. Anyone attending the Winter Olympics has to buy a ticket online from the organizers and obtain a spectator pass that requires providing passport details. Authorities have already barred access to all cars registered outside of Sochi and Russian police have gone house-to-house methodically screening all city residents. Soldatov argued, however, that Russias massive security presence at the Olympics could also have an adverse effect. "When you put so many troops on the ground, you might get some problems with the co-ordination of all these people," he said. Soldatov noted that the ominous threat of a "present" for the visitors to the Games contained in the video is loosely phrased and could herald an attack outside tightly guarded Olympic facilities. "They never tried to specify the place where they might strike, thats why everybody should be concerned," he said.

Josh Jacobs Womens Jersey .TV Series: Duck Dynasty.WINNIPEG -- They lost out on the Henry Burris sweepstakes but the Winnipeg Blue Bombers didnt wait long to land another quarterback, acquiring Drew Willy Thursday from the Grey Cup-champion Saskatchewan Roughriders for Canadian receiver and Regina native Jade Etienne. Winnipeg also signed Willy to an extension, reportedly for two years. He was scheduled to become a free agent next week and will be unveiled by the Blue Bombers on Friday at Investors Group Field. "Drew is a quarterback we have always thought had very high potential in this league," said Winnipeg GM Kyle Walters. "He immediately upgrades us at this position and we really look forward to him being a part of the Winnipeg Blue Bombers moving forward." But is he a starter who can win regularly, something a team that finished with a league-worst 3-15 record last season so desperately needs? Playing behind Darian Durant, Willy doesnt have a lot of experience. He posted a 2-2 record in his two seasons with the Roughriders and, at least on paper right now, is competing for the starters job with Max Hall and Justin Goltz. The six-foot-three, 215-pound Willy was 32-of-52 passing last season for 474 yards with four touchdowns and one interception. He saw more action in 2012, completing 69-of-95 passes for 709 yards, five TDs and four interceptions. Riders coach Corey Chamblin, named the CFLs coach of the year Wednesday after leading Saskatchewan to a their fourth Grey Cup title, has praised Willy for his composure. Willy wasnt Winnipegs first choice. He joins the Blue Bombers after they lost out to the expansion Ottawa Redblacks for the services of free-agent Burris, the CFLs passing leader last season who was released by the Hamilton Tiger-Cats. Hall became Winnipegs starter last year as the Bombers struggled through a series of quarterbacks and traded veteran Buck Pierce to the B.C. Lions. Goltz, who had been considered by many to be the teams future, failed to measure up when he finally got his shot.dddddddddddd Willy, 27, is a native of Randolph, N.J., who spent some time in the NFL on practice squads in Indianapolis, Baltimore, San Diego, and New York and played in the UFL with Las Vegas in 2010. "I am really excited to join the Blue Bomber organization," he said in a statement. "The support the team gets from the province of Manitoba is remarkable. "With such a deep history, the fans, the new stadium, and the direction the team wants to go, its going to be a great place to play. The people within the organization have shown genuine interest in me, and as a player, you cant ask for anything more." He started two games in 2013, going 1-1. He earned his first CFL win as a rookie in a come-from behind victory at Winnipeg in the Banjo Bowl, where he completed 17-of-23 for 188 yards and a touchdown and ran for another. Willy played at the University of Buffalo, where he was the most prolific passer in school history, setting records for completions (849), attempts (1,322), yards (8,748), touchdowns (52), total offence (8,639), and completion percentage (64.2). "He is a quarterback with great promise in our league," said Danny McManus, himself a Canadian Football Hall of Fame quarterback and Winnipegs new assistant general manager and director of U.S. scouting. "Drew has the attitude and determination you look for at the quarterback position. "He is physically and mentally tough, and can endure the challenges a quarterback faces, day in, and day out." Etienne, 24, was an off-the-board first round pick of the Blue Bombers in the 2011 draft and after three CFL seasons had 20 receptions for 276 yards and two TDs. But he didnt see a lot of action until 2013 when he had 19 catches for 265 yards and the two touchdowns. Like Willy, Etienne was set to become a free agent next week. ' ' '
