The General Staff of the Korean People´s Army issued the denial Saturday through the official Korean Central News Agency. Seoul on Thursday said Pyongyang was responsible for the March 20 computer crash.[break]
The denial comes as tension remains high on the Korean Peninsula. U.S. and South Korean officials say North Korea appears to be preparing to test-launch a mid-range missile that could fly as far as Guam.
The North has released a chain of warlike threats since Seoul and Washington began joint military drills last month. Pyongyang is also angry over new U.N. sanctions punishing it for its Feb. 12 nuclear test.
