Despite North Korea\'s recent warning to foreign diplomatic missions to leave Pyongyang, no embassy has yet to make a move out of the communist state, Seoul officials said Saturday.We don\'t believe there\'s any foreign mission about to leave Pyongyang,\" one South Korean government official said. \"Most foreign governments view the North Korean message as a way of ratcheting up tension on the Korean Peninsula.\"According to media reports Friday, which have since been confirmed by Seoul and Washington, North Korea\'s foreign ministry asked embassies based in Pyongyang to leave, saying a war could break out soon and the safety of foreigners is not guaranteed.
