Korea Threatens Military Action in Disputed Waters VOA News 25 May 2010 South Korean activists burn a North Korean flag with a picture of North Korean leader Kim Jong Il during a rally against the North near the National Assembly in Seoul, South Korea, 25 May 2010 Photo: AP South Korean activists burn a North Korean flag with a picture of North Korean leader Kim Jong Il during a rally against the North near the National Assembly in Seoul, South Korea, 25 May 2010 North Korea threatened Tuesday to take military action if South Korea trespasses in its waters off the peninsula's west coast. The two countries have been in a tense standoff about a disputed maritime border in the Yellow sea that was the scene of a torpedo attack that sank a South Korean warship in March. A team of international investigators concluded last week that a North Korean submarine fired the torpedo.  Pyongyang denies the charge. South Korea is preparing to resume propaganda broadcasts into North Korea despite the North's threat to fire on and destroy loudspeakers if the South starts broadcasting anti-communist propaganda. The broadcasts are part of a series of sanctions announced by South Korean President Lee Myung-bak Monday in response to the sinking of the South Korea warship. Other measures include severing all inter-Korean trade and closing the South's sea lanes to North Korean ships. The South Korean president also said he will ask the U.N. Security Council to impose new sanctions on North Korea.  United Nations Secretary-General Ban Ki-moon said Monday there is "overwhelming" evidence that a North Korean torpedo sank the South Korean warship, killing 46 South Korean sailors. The South Korean-born U.N. chief told reporters in New York that he fully shares the widespread condemnation of the incident. He called on the U.N. Security Council to take "appropriate" measures after one of South Korea's worst military disasters since the Korean War. U.S. President Barack Obama said he fully supports the South Korean leader's actions. The U.S. Defense Department has announced that it plans to conduct two previously unplanned naval exercises with South Korea's military in the "near future." A State Department spokesman said Washington and Seoul will seek to put together a "strong, concerted international response." The United States is also enlisting Japanese support for tough international action. U.S. Defense Secretary Robert Gates is holding talks in Washington Tuesday with his visiting counterpart, Toshimi Kitazawa. The South Korean president said his government is not looking for a military confrontation and will continue minimal shipments of humanitarian aid to the impoverished North.  Some information for this report was provided by AP, AFP and Reuters. .
