A retired spy soldier who was trained to infiltrate into North Korea walks past memorial tablets for his dead colleague soldiers, set temporarily by another colleagues, at the Seoul City Hall plaza on the eve of South Korea's Memorial Day June 5, 2008. Protesters fearing the infection of mad cow disease, were going to hold a candle-lit vigil in the plaza but changed the venue because of the memorial event. Protesters demanded the full-scale renegotiation of a beef deal with the U.S. and the resignation of President Lee Myung-bak at the rally. REUTERS/Lee Jae-Won (SOUTH KOREA)
