Demonstrators chant slogans at a rally in Seoul August 2, 2008. About 1,000 protesters demonstrated in Seoul on Saturday as they demanded the resignation of President Lee Myung-bak, U.S. President George W. Bush not to visit South Korea and the renegotiation of the U.S. beef import deal. Tens of thousands of Koreans took to the streets for three months starting in May, demanding U.S. beef stay out of the country because they fear it still poses a mad cow disease risk.
