South Korean protesters burn anti-North Korean banners at a rally in Seoul October 9, 2006 denouncing North Korea's reported nuclear test. North Korea said on Monday it had safely and successfully carried out an underground nuclear test, flying in the face of a warning from the U.N. Security Council and opening its crippled economy to the risk of fresh sanctions. The words on the banner reads "Down with dictator Kim Jong-il". REUTERS/Kim Kyung-Hoon (SOUTH KOREA)
