Protesters wearing masks march during a rally to demand the full-scale renegotiation of the U.S. beef import deal and the resignation of South Korean President Lee Myung-bak, near Seoul City Hall July 5, 2008. Polls show that most South Koreans oppose a U.S. beef import deal President Lee struck in April to open the market to U.S. beef but about two-thirds of respondents say it is also time to halt the rallies that have grown more violent in recent weeks. The characters on the papers read "Eventually, this candle-lit rally will win". REUTERS/Jo Yong-Hak (SOUTH KOREA)
