[Kyodo: Korea] The top command of North Korea"s Korean People"s Army ordered all nationals and military forces Monday to be on ""special alert"" over a joint U.S.-South Korean military drill that began the same day, the official Korean Central News Agency said. The order from the Supreme Command, whose supreme commander is North Korean leader Kim Jong Il, suggests an unusually tough stance on the Ulji Freedom Guardian joint military exercises, which run through Aug. 27.
