An Afghan border policeman fires on Taliban fighters hidden in the Traffic Department building, where smoke rises from the rooftop, in Kandahar, Afghanistan, on Sunday, May 8, 2011. The Taliban unleashed a major assault Saturday on government buildings throughout Kandahar, Afghanistan's main southern city, an attack that cast doubt on how successful the U.S.-led coalition has been in its nearly yearlong military campaign to establish security and stability in the former Taliban stronghold.
