[EX Q]: 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.

[EX Q]: LONDON, England (CNN) -- London commuters crammed onto buses, scrambled for taxis, cycled or simply walked on Wednesday as a strike by Tube workers shut down most of the subway network. Commuters queue for packed buses in London on Wednesday morning. The strike began Tuesday at 7 p.m. (2 p.m. ET) but the first full effects were felt during Wednesday's morning commute. The strike was set to last for 48 hours with a normal service resuming Friday morning, according to Transport for London (TfL), which runs the city's transportation network. The RMT trade union called the strike after talks with management over pay, job cuts, and disciplinary issues broke down. "RMT doesn't resort to industrial action lightly," General Secretary Bob Crow said in a statement. "The fact is that Tube workers have been driven into walking out today." Transport Commissioner Peter Hardy said the talks had been making progress on all issues and he urged the RMT to return to the table. "The RMT leadership says we were close to a deal," Hardy said in a statement. "If that is the case, then they should call off the strike, return to talks ... and resolve this issue without any more disruption to Londoners." TfL was running extra buses and free shuttle services across the River Thames during the strike. Electronic travel cards used for the TfL network were temporarily being allowed on all train lines in greater London, it said. While most services on the Tube were shut because of the strike, one line -- the Northern line -- was running normally and five others were running on a reduced schedule, TfL said. "It's been really good," a girl on Oxford Street told CNN about her commute. "The Northern line is running perfectly." Still, some bus services were packed with commuters who normally ride the underground trains or who failed to find a taxi. "I think we'd all like to strike for more money, but unfortunately we can't," said one woman at Oxford Circus, where the Tube is closed. Others hit the pavement and walked. "It's OK -- quite refreshing," said a man on Regent Street. He said he had just walked from Liverpool Street Station, a train station as well as a Tube stop that is more than 2.5 miles away. The RMT represents about half of the 20,000 employees on the Tube, a TfL spokeswoman said. Other unions including Unite and TSSA represent the rest, she said, and were not on strike.

[EX Q]: Thirty miles from Hong Kong's Disneyland park, a small fishing village offers a contrasting view of the city's past. Located in the southwest corner of Lantau, Hong Kong's largest island, Tai O is connected to the outside world via a narrow mountain road.  It has a view contrary to expectations for one of the world's most crowded cities: There are no skyscrapers, no neon signs or real estate companies. The few shops in village close at 5 p.m., when the nightlife on Hong Kong Island has yet to spark. In recent years, tourists have been flocking to Tai O to glimpse this part of Hong Kong's rapidly disappearing past. But when they arrive, they are greeted by a placard at the bus station decrying: "Mass development will destroy Tai O." It's a sign of the times: Even as tourists boost the coffers of a local economy once dependent on fishing, villagers are deeply ambivalent about the hordes of visitors encroaching on their seaside hamlet. "We are going to lose our distinctive way of life and identity if no one protests against the government plan," said lifelong Tai O resident Wang Waking, 51, who runs the Tai O culture workshop. "I am afraid that the commercially-driven plan is going to turn Tai O into another resort." Villagers like Wang are torn by government plans to add fountains, sculptures and a stage next to the temple to Tin Hau, where generations of fishermen prayed for safety before sailing. The government's US$100 million "Revitalize Tai O" project will also replace patches of wetland by boardwalks and a new plaza will rise near the dock. The project is scheduled to be completed later this year, according to the Hong Kong's Civil Engineering and Development Department spokesperson Carol Ho. Original plans called for tearing down all the village's distinctive stilt houses, but was curtailed after protests by villagers. While the redevelopment celebrates Tai O's seafaring heritage -- in 1960, villagers caught 30% of all seafood sold in Hong Kong, according to the book "Tai O History" -- it comes in the wake of a 2012 Hong Kong law banning of commercial trawling. That move was applauded by environmentalists but decried by local fishers. "It wrecks my heart to see fishermen forced to sell their large trawlers," said a local fisherman surnamed Wong, who says he catches 70% less after the ban.  Wong, who sells homemade shrimp paste, now must import shrimp from mainland China. Tai O is separated from the rest of Hong Kong by steep, rocky hills. Before 1990, the only way to get to Tai O was by boat. Permits to drive on the town's single road are only granted to villagers and public buses. A sense of isolation still pervades the village's tight-knit community, which many locals say they are keen to keep to themselves. As visitors are drawn to the Venice-like village with homes largely built on stilts, the pathways are dotted with signs warning "Private Property" and "No Entry." To circumvent the signs, tour guides now row tourists on boat down the river and having a look at the houses from the water. Besides tourism, real estate development could change the fortunes of the town, as Hong Kong has one of the world's most expensive real estate markets. Yet villagers say they are actively working to keep property among themselves. "I can't tell you how many people are interested in our house," said resident Ines Wong. But villagers do all their real estate business by word of mouth to keep outsiders out of the property market, Wong said. "The fact is that outsiders don't know where to buy property at Tai O. And even if demand for Tai O property is high, local people tend to sell to locals," she said. Wong, 24, grew up in Tai O, but like many other young people here, was forced to find work in other parts of the city. She eventually moved to Kowloon, which sits across Victoria Harbor from Hong Kong Island, where she started working for a large bank. While she found it hard to leave her home, she said she had little choice. "Tai O has no job market at all. I don't see what I can do. Selling salt fish with a degree in marketing?" While Wong decries the impact of tourism, many of her peers who still live in Tai O welcome the government tourism plan. "We are one of the oldest communities in Hong Kong. If Tai O has nothing to offer to its young residents, it may become a dead town in a few years," said Paul Lieu, 30-year-old local resident. Lieu landed on a job as a tourist guide last year. He makes 30% less than a similar job in other parts of Hong Kong, but he enjoys the commute-free work. Before tourists poured in, the only local job Lieu could find was temporary construction work. Now young people start small business like transforming their stilt homes into guesthouses or waterfront cafés. "I think Tai O has lost part of its unique character with all the development going on. But that the price we pay to get a better life and to help this community to survive," he said. For Wang, the changes are attacking a way of life. "Tai O people have deep feeling for the mountains, rivers and wetlands surrounding us, because we live so close to nature," she said. "With the boardwalk, children lose a good place to find clams."
