South Korea today rejected North Korea's proposal for direct military talks on the sinking of a warship, saying the issue should be handled under the armistice which ended their 1950-53 war. In response to a new offer by Pyongyang to hold inter-Korean talks on the issue, the foreign ministry spokesman, Mr. Kim Young-Sun said Seoul should focus on discussions at the UN Security Council. He said it is more appropriate to hold general-level talks between the United Nations Command and North Korea's military and address the issue within the framework of the armistice agreement. Tensions have been high since the South, citing findings of a multinational probe, accused the North of torpedoing a corvette with the loss of 46 sailors near the disputed sea border.
