North Korea is using Seoul's decision to deploy an advance antimissile system on its soil to intensify hostility toward South Korea, a media report citing sources in the reclusive country said Tuesday.

A source in North Hamgyong Province told Radio Free Asia that North Korea's propaganda machine has harshly criticized Seoul's decision to deploy the Terminal High Altitude Area Defense system.

According to the RFA, the source said lectures to the public include the claim that the development of THAAD is a blatant attempt to trigger a nuclear war on the Korean Peninsula.

The source said that Pyongyang has blasted the South Korean government for pushing for regime change in North Korea and even argued it launched what it called "decapitation operations" targeting top North Korean leaders.

Another source in North Pyongyang Province said North Korean authorities have been conducting intensive, organized lectures for the public that say, "The (South Korean) enemies are launching operations to demolish the North Korean regime by harming the dignity, autonomy and right to live for North Koreans."

Over the past decades, North Korea has driven its people and party members into an anti-imperialist struggle whenever it needs internal consolidation, RFA said, adding that the reclusive country is trying to create a tense situation in the communist country, as well as on the Korean Peninsula.

South Korea and the United States said that the THAAD antimissile system will counter North Korea's growing missile capabilities.

North Korea's military has said that its army will deal a ruthless retaliatory strike and turn (the South) into a sea of fire and a pile of ashes because of the missile system. (Yonhap)
