(AP Photo/Ahn Young-joon) As South Korea continued to run artillery drills, North Korea warned today that the South's cooperation with the US and Japan is "nothing but treachery"—and could result in nuclear war. An official said that South Korea's live-fire drills, which are running through Friday, are routine and would not take place near the disputed sea border. Even so, North Korea lashed out at the South via its official news agency, the AP reports. Cooperation between the three nations is "escalating the tension between the North and the South and bringing the dark clouds of a nuclear war to hang over the Korean peninsula," read the North Korean newspaper commentary. South Korea, the US, and Japan said last week that negotiations with North Korea will not resume until the North stops, as Adm. Mike Mullen put it, its "belligerent, reckless behavior." South Korean and US officials met again today for regular defense talks. Read These Next Country star cancels rest of his tour: 'I am mentally unwell.'
