Hong Kong ( CNN ) -- North Korea said Monday that it would soon initiate `` special actions '' aimed at destroying the South Korean president and his government . North Korean armed forces will use `` unprecedented peculiar means and methods of our own style '' to carry out the actions , the official Korean Central News Agency said in a report , adding that the operation would take 3 or 4 minutes . It did not specify what those actions would involve . An unusual broadcast on North Korean state television also announced the planned measures and showed images of people throwing rocks at a caricature of Lee Myung-bak , the South Korean president . North Korean state media have consistently lambasted the conservative Lee and his administration . Recent reports have described them as `` rats . '' One of the main motivations for the threats Monday appears to have been the announcement last week by the South Korean military that it had deployed a cruise missile capable of striking any site in North Korean territory . That move showed that Lee 's government `` has long lost its reasoning power , '' the KCNA report said Monday , citing the Supreme Command of the Korean People 's Army . The South Korean Unification Ministry did not have an immediate comment on the statements from Pyongyang . The menacing comments from the North follow its failed launch of a long-range rocket earlier this month , which exacerbated tensions in the region . South Korea and the United States described the rocket launch , which Pyongyang said was to put an `` earth observation satellite '' in orbit , as a long-range missile test in disguise . CNN 's Judy Kwon contributed to this report .
