Anti-war and pro-unification activists attend a rally opposing South Korea's planned firing drill on Yeonpyeong Island, in front of the defence ministry in Seoul December 20, 2010. South Korean marines have ordered residents of Yeonpyeong island to move to air raid bunkers in anticipation of a live-fire drill on Monday. North Korea has threatened to strike if the South went ahead with the drill from the island off the Korean peninsula's west coast and in disputed waters between the rival Koreas. Placard reads,"Stop artillery firing drill, which leads to full scale war!". [Photo/Agencies]
