North Korea Accuses CIA of Bio-Chemical Plot

North Korea on Friday accused the US Central Intelligence Agency and South Korea's intelligence service of a plot to attack its "supreme leadership" with a bio-chemical weapon and said such a "pipe-dream" could never succeed.

Tension on the Korean Peninsula has been high for weeks, driven by concern that North Korea might conduct its sixth nuclear test or test-launch another ballistic missile in defiance of UN Security Council resolutions, AOI reported.

Reclusive North Korea warned this week that US hostility had brought the region to the brink of nuclear war.

The North's Ministry of State Security released a statement saying "the last-ditch effort" of US "imperialists" and the South had gone "beyond the limits."

"The Central Intelligence Agency of the US and the Intelligence Service of South Korea, hotbed of evils in the world, hatched a vicious plot to hurt the supreme leadership of the DPRK and those acts have been put into the extremely serious phase of implementation after crossing the threshold of the DPRK," the North's Korean Central News Agency quoted the statement as saying, referring to the north by its official name, the Democratic People's Republic of Korea.

"A hideous terrorists' group, which the CIA and the Intelligence Service infiltrated into the DPRK on the basis of covert and meticulous preparations to commit state-sponsored terrorism against the supreme leadership of the DPRK by use of bio-chemical substance, has been recently detected."

The US Embassy in Seoul and South Korea's National Intelligence Service were not immediately available for comment.

The US military has said CIA Director Mike Pompeo visited South Korea this week and met the NIS chief for discussions.
