Seoul, South Korea (CNN) -- South Korean marines detained an American man on the bank of a river bordering North Korea late Tuesday, according to a South Korean Defense Ministry official and a senior U.S. State Department official. The marines were on a regular patrol mission west of Seoul when they caught the man by the Han River in an area where it divides North and South Korea. The U.S. citizen was being interrogated Wednesday, the defense ministry official said, adding that it was not immediately known whether the American was trying to cross into North Korea. The U.S. Embassy in Seoul said it was "aware of the reports that a U.S. citizen has been detained attempting to swim from South Korea to North Korea." The Embassy said it had been in contact with South Korean authorities but didn't have any additional information to share. Americans are allowed to travel to North Korea, usually arriving by plane from Beijing. But it's forbidden to cross from South Korea into North Korea. The U.S. State Department warns citizens against all travel to the authoritarian state led by Kim Jong Un. Three U.S. citizens are currently in detention in North Korea: Kenneth Bae, Matthew Todd Miller and Jeffrey Fowle. A North Korean court on Sunday sentenced Miller to six years hard labor for committing "acts hostile" to North Korea, although the circumstances surrounding his alleged crime remain murky. Bae, a Korean-American missionary, is serving a 15-year sentence for allegedly trying to bring down the North Korean government. Fowle, who was arrested in June while traveling as a tourist, is still awaiting trial. Fast facts on detained Americans . CNN's K.J. Kwon reported from Seoul, and Jethro Mullen from Hong Kong.

(CNN) -- He's just 15 and the world is seemingly already at his feet. Last month, Martin Odegaard became Norway's youngest international footballer in a friendly against the United Arab Emirates, provoking huge media interest and the hungry attention of Europe's top clubs. Such is the focus on the midfielder that 35 scouts from some of those teams -- including Manchester United and Liverpool of the English Premier League -- came to watch him at a recent Under-21 match. "In the beginning it was unreal and a little bit surreal that all these clubs wanted Martin, but it's strange what you can get used to," his father Hans Erik Odegaard tells CNN. "Almost every top European club has been in touch." His international debut is not Odegaard's only record-breaking feat this year. In April he became the youngest player in the history of the Tippeligaen when he made his debut for Stromsgodset in a top-flight game against Aalesund. He followed that up by scoring the fourth goal in a 4-1 win over Sarpsborg to become the youngest scorer in the Norwegian league. Former Norway international Morten Gamst Pedersen has described Odegaard's potential as "unbelievable," while manager Ronny Deila -- who gave the teen his Stromsgodset debut before joining Scottish club Celtic -- says he can "become the best in the world." Odegaard's father, a former footballer at Stromsgodset and Sandefjord, recalls the moment when he realized his son might have what it takes to play professionally. "I saw from a very early age that 'he had the feeling,' but I remember very well when I knew he'd be quite good," he said. "I was still playing and Martin must have been no more than eight. I was out on the pitch running some intervals. He was, as always, with me. When I was finished I wanted to go home, but we couldn't before he had done 50 more shots (at goal). "Then I understood he also had a talent for training and that is the most important talent you can have." "Quite good" probably doesn't do Odegaard's myriad talents justice, given he has been compared to Lionel Messi or -- closer to Scandinavia -- the legendary Denmark international Michael Laudrup, who played for Juventus, Barcelona and Real Madrid. "I'm sure you can compare him with many, but I don't like to do that," reflects Hans Erik. "Those players are and were so good and Martin is at the start of his career." Former Monaco chief executive Tor-Kristian Karlsen, who is Norwegian and has watched Odegaard's progress over the last few months, is a fan. "He's obviously still in the early stages of his development but his understanding of the game is very impressive," says Karlsen. "He plays in bursts, so you might not notice him for five minutes, but he has good movement and can take people on." Young, gifted and talented . Books such as Malcolm Gladwell's "Outliers," Geoff Colvin's "Talent is Overrated" and "The Talent Code" by Daniel Coyle all explore the idea that to become an expert you need to practice any skill for 10,000 hours. What's clear from Odegaard's prodigious development is that his success has been helped by a specialized training regime and his thirst to learn and practice. "I have been a regional trainer for the best boys in this area, and I checked how much they trained with the team and by themselves," says Hans Erik. "Martin is training more than double than these boys did -- at least 20 hours a week." It's not just how much he trains -- it's also the type of training he has focused on by doing everything with the ball. "The boys loved it when I joked about other teams that warmed up with running instead of using the ball," adds Hans Erik. "I always said that they should maybe do athletics." Hans Erik believes Martin has been able to cope with the demands of professional football and making his international debut at such an early age because of the work done to develop his first touch and "quick feet." "It's the pace of the game that makes the difference in adjusting to different levels," says Hans Erik. "We've used so many hours in working with his first and second touch to take off the pressure. "We have worked a lot on bringing the ball closely to his feet, so he can change direction quickly, so even if he's physically weaker than the others he doesn't get caught because he's able to get away." Family fortunes . Now 40, Hans Erik admits that, as a player, he was "a runner with a big heart and scored some goals" -- so does Martin's talent come from his mother Lene? "She played handball and sprinted," says Hans Erik, before joking: "She tells us she was fantastic, but none of us, or any others, has seen that." While Hans Erik's professional career has given him advantages in overseeing Martin's progression as a player, he admits it has given him difficulties as a father in his relationship with his son. "I was always afraid of favoring him. We were always changing captain, but he was never picked," he says. "The expectations were high on him so it happened that I sometimes yelled at him and one day another parent came to me and said that I was too hard with Martin. "Then Martin and I agreed that he should always get the feedback when we were alone in the car after the game. That was a good solution. "We've always -- and still do -- talked so much about football. His natural understanding for the game makes him a very smart player. Since he was 10 I could discuss football with him as an adult." Stay or go? Hans Erik, who has so far avoided using agents to advise on his son's career, concedes that "the level of the Norwegian league isn't as strong as many other European leagues." So what's next for the wunderkind from the port city of Drammen who has already visited Manchester United as well as German clubs Bayern Munich, Stuttgart and Borussia Dortmund? Karlsen believes going to a country like the Netherlands would benefit the 15-year-old. "If he went to some other countries they might take something out of his game, by telling him to get rid of the ball," Karlsen says. "In Holland, they are not so concerned with the results." Whatever Odegaard does next, his father insists the decision will not be influenced by money. "In the end it's all about development," he says. "Nothing else matters. I'm allergic to boys who are satisfied getting into an academy or winning a first-team contract, because you haven't achieved nothing . "It's a danger when there's so much attention to him from clubs and the media. I think he has handled it very well so far and he has his feet on the ground. "When we are talking with the clubs we have just talked about sport. We're also in a position that it's not obvious that he will go abroad now." And amid all the hype and record breaking, Odegaard's father insists that his son's education will not be forgotten. "He will still, of course, go to school. I don't think it's good for any young boy just to play football and PlayStation. You need to work with your brain too and to develop as a person."

Washington (CNN) -- A Russian company is seeking to buy a controlling interest in one of the largest uranium extraction operations in the United States -- a sale that requires U.S. government review because of possible national security implications. Uranium One USA, now a subsidiary of a Canadian company, operates a uranium processing facility in Wyoming and has assets in Utah, Texas and Colorado. The sale of the company's existing and pending operations could give Russia control of about 20 percent of U.S. uranium extraction capacity, Nuclear Regulatory Commission officials estimate. Industry observers tell CNN they do not believe the sale of Uranium One to Joint Stock Company Atomredmetzoloto, or ARMZ, would jeopardize U.S. security, saying that the United States relies on Russian dismantled nuclear weapons for much of the uranium used in nuclear reactors today, and that sources of uranium are plentiful. "I have no concerns about it at all," said Fred McGoldrick, former director of the State Department's Office of Nonproliferation and Export Policy. "I don't see any national security threat to the United States from the Russians partly or entirely owning a mine in the United States." He added, "The Russian's aren't coming. They came and went. They are no longer the Soviets. I think it's to our mutual interest that we cooperate with the Russians." Said Ed Lyman of the Union of Concerned Scientists, "Looking at the big picture here, I don't really think this has major security implications. I'd be interested in hearing arguments otherwise, but I just don't see it." In an application submitted to the NRC, JSC Atomredmetzoloto, which currently owns 23.1 percent of Uranium One's common stock, says it is seeking to buy a controlling 51 percent interest. The Russian company is controlled by Rosatom, the Russian government agency that oversees Russia's nuclear industry. Uranium One would continue to be publicly traded on the Toronto Stock Exchange, its U.S. facilities would remain under their current management teams and five of the nine directors on the company's board would be non-Russian, the company said. "The bottom line is any of the uranium we buy or sell has to be used for peaceful purposes and it's subject to all the safeguards of the International Atomic Energy Agency, the Nuclear Suppliers Group, Euratom (the European Atomic Energy Community), or any other governmental agency having jurisdiction over the United States" and customer countries, said Chris Sattler, spokesman for Uranium One. Uranium One USA is involved in the "recovery" of uranium, a form of mining in which a solution is injected into an ore body and the uranium leaches into the solution, which is then extracted, said NRC spokesman David McIntyre. The company is licensed to produce up to 2.5 million pounds of uranium a year, it said. Stockholders approved the sale August 31, Sattler said, but the companies are awaiting approval from numerous regulatory agencies in the United States, Canada, Australia and Kazakhstan. The NRC must approve the transfer of the NRC license for its Irigaray-Christiansen Ranch recovery facility in eastern Wyoming, McIntyre said. "Generally, we look at whether the new ownership would have the technical expertise and the financial wherewithal to maintain the site and clean up when operations cease," he said. Further, the sale needs to be reviewed by the Committee on Financial Investment in the United States, an inter-agency panel that advises the president on any transaction that could jeopardize U.S. national security. Committee officials declined to discuss the sale, saying they are prohibited by law from disclosing such matters. And the sale may require approval of the Federal Trade Commission because it involves a stock transaction, and the Federal Communications Commission because one of the sites has a radio license, the NRC said. The NRC released details of a pending license transfer in the Federal Register, in an item giving the public an opportunity to request a hearing on the issue. The NRC involvement is limited to the company's operations in Wyoming. The states of Texas and Utah regulate uranium mining operations there.
