South Korean riot police surround protes

South Korean riot police surround protesters to block a rally protesting against government's policy on US beef imports in front of the Seoul City Hall in Seoul on July 6, 2008. Protestors are intensifying their battle against importing US beef, which the government has agreed to as a part of bilateral efforts to implement the 2007 free trade agreement. Seoul's decision in April to resume the imports, which were halted in 2003 after a US mad cow case, has sparked weeks of mass demonstrations, originally over health concerns. Opponents claim the imports carry the risk of the human form of mad cow disease, despite US and South Korean government assurances the meat is safe.
