North Korea's state-run KCNA news agency is out with a doozy of a report: It says the North has "uncovered and smashed" a plot by the CIA and South Korea's Intelligence Service to assassinate Kim Jong Un. The North says the two agencies worked in cahoots with a North Korean citizen and an unnamed terrorist group on the plot, which involved using a "biochemical substance" on Kim, reports the BBC. The idea was apparently to deliver some kind of slow-acting poison, possibly at a military parade, that would kill the North Korean leader over the course of six months to a year. The report said the "terrorists" who were to carry out the plot had entered the country, but the North said it would "mercilessly destroy" them.
As for the traitorous North Korean citizen, the report said only that he had a surname of Kim. Pyongyang, of course, is known for its far-out claims, though CNN notes that South Korea has previously acknowledged having plans in place to assassinate Kim. Still, this latest claim is likely to be bogus and just part of the recent war of words between the countries, a professor at Tongji University in Shanghai tells the Washington Post. "There is no doubt that the United States and South Korea have been thinking about eradicating Kim Jong Un, but it is hard to put into practice," he said. There's no official reaction from the US or South Korea. (Read more North Korea stories.)
