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 But he rescinded that order in July, urging his followers to strike the Sochi Olympics, which he denounced as "satanic dances on the bones of our ancestors."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. Anthony Hitchens Jersey .

"I think any fun about pitching against them disappeared this morning with the news of Tony passing," the Mariners right-hander said after Seattles 5-1 win over San Diego on Monday night. "My condolences go out to his family, the Padres organization, the city of San Diego. He meant a lot to everyone there and Im grateful I had the opportunity to work with him and get to know him." The loss capped a sombre day for the Padres organization. Gwynn, 54, died Monday morning of oral cancer, a disease he attributed to years of chewing tobacco. "Even though were away from San Diego I think the Mariners did a good job of putting Tony out there," Padres manager Bud Black said. Kyle Seager hit a three-run homer in the first inning, Brad Miller added a solo shot, and Young threw six shutout innings against his former team. San Diego was on the verge of being shut out by Young (6-4) and a pair of relievers until Carlos Quentin hit a solo homer leading off the ninth. But Gwynn was on everyones mind at Safeco Field. Seattle honoured Gwynn with a video tribute and moment of silence before the game and put a 19 on the dirt in the hole between the shortstop and third baseman. Gwynn called that the "5.5 hole" and many of his 3,141 hits went through it. San Diego added black armbands to its uniform in honour of Gwynn, and his No. 19 jersey hung in the Padres dugout. His jersey also was scattered among fans in attendance. "He is the city of San Diego. You talk Padres baseball, Tony Gwynn is everything there," Young said. Seagers homer came on a 3-0 pitch from San Diego starter Tyson Ross (6-6). Coming off a 4-for-4 performance on Sunday, Seager was given the green light and hit his 10th homer of the season. Miller followed with a ssolo homer an inning later.dddddddddddd. Robinson Cano added an RBI double as Seattle scored all five runs in the first two innings. Seager leads Seattle in home runs and has seven hits in his last 10 at-bats with six RBIs. James Jones also stole three bases and scored twice for Seattle. "Its a good feeling that the skipper has confidence in you, thats always good," Seager said. "In that situation I had seen a couple of pitches ... when you get the opportunity you have to make sure you capitalize and get a ball in the air. Young was once an All-Star for the Padres and has become a valuable acquisition since joining Seattle at the end of spring training. After losing his last two starts, Young gave up two hits in the first inning and then cruised. He retired 16 of the final 19 batters he faced, giving up a pair of singles and issuing one walk. He matched his season high with six strikeouts. Joe Beimel, who gave up the final home run in Gwynns career, pitched one inning of relief for Seattle. Tom Wilhelmsen then got the final six outs, but couldnt complete the shutout giving up Quentins third homer of the season. Ross had allowed only one homer in his previous six starts, but struggled all night. He walked a career-high seven and at least one in every inning. Ross pitched into the sixth inning and helped save the Padres bullpen. "My command wasnt very sharp tonight," Ross said. "I kind of grinded through some innings there and overall just wasnt in the strike zone early and often enough." NOTES: Young has now faced all 30 teams in the majors. ... Seattle hopes to send injured 1B Justin Smoak (quad) out on a rehab assignment Wednesday. Corey Hart (hamstring) and Michael Saunders (shoulder) could join Smoak on rehab assignments by the end of the week. ... In 11 career games against Seattle, Gwynn hit .261 (12 for 46) with three doubles and four RBIs.
