By Richard Balmforth and Alissa de Carbonnel KIEV (Reuters) - Ukrainian riot police early on Wednesday poured into Kiev's Independence Square, confronting opposition leaders and protesters demonstrating against a government decision to rebuild trade ties with Russia rather than move closer to the European Union. Black-helmeted police entered the square in the heart of the snowbound capital where the demonstrators have been camping out for the past 10 days, tearing down barricades erected by the protesters. Clashes broke out as police tried to detain some of the protesters.
US air accident investigators hold a hearing Wednesday into the role that sophisticated cockpit automation might have played in the fiery crash of a South Korean airliner in San Francisco. Three passengers died when Asiana Airlines Flight 214 clipped a seawall, skidded out of control and burst into flames upon landing after an otherwise routine flight from Seoul on July 6. Another 182 passengers and crew aboard the Boeing 777 were injured -- and first indications suggested the pilots approached the runway at well below the optimum speed for landing. Wednesday's nearly 12-hour hearing was supposed to be a two-day affair, but its scheduled start Tuesday was postponed due to a federal government shutdown prompted by wintry weather in Washington.
