North Korea is accusing US and South Korea of attempting to assassinate Kim Jong Un with a "bio-chemical substance"

North Korea has just accused the United States and South Korea of attempting to assassinate leader Kim Jong Un with a "bio-chemical substance." In a report released today which offered no evidence, North Korean state news agency KCNA said a "hideous terrorist group" conspired with the CIA and South Korea's Intelligence Service (IS) to mount the attack.
The report said the aim of the attack was to "commit bomb terrorism targeting the supreme leadership" during major events including a recent military parade.

The report also claimed a North Korean citizen was involved in the plot, using "biochemical substances including radioactive substance and nano poisonous substance" to target Kim.
