North Korea has accused the Central Intelligence Agency of plotting with South Korea to assassinate Kim Jong-un, the isolated country's leader, as tension soars in the flashpoint region.
This comes as tensions between Pyongyang and the administration of President Donald Trump escalates over United States military build-up on the Korean Peninsula and the North's carrying out nuclear and missile tests.
The statement carried by the state-run Korean Central News Agency (KCNA) claimed that the US Central Intelligence Agency and the Intelligence Service of South Korea infiltrated the group into North Korean territory.
In this Saturday, April 15, 2017, file photo, North Korean leader Kim Jong Un waves during a military parade in Pyongyang, North Korea, to celebrate the 105th birth anniversary of Kim Il Sung, the country's late founder and grandfather of current ruler Kim Jong Un.
Still, as AP describes it, the new accusation marks a departure from the frequent bluster from Pyongyang directed at the US, as it "was unusual in its detail".
"They handed him over $20,000 on two occasions and a satellite transmitter-receiver and let him get versed in it".
On Saturday North Korea conducted its second failed ballistic missile test in two weeks.
The statement said a North Korean identified only by the surname "Kim", had been "corrupted and bribed" by South Korean intelligence services while he was working in Russian Federation.
The KCNA news agency frequently carries bellicose rhetoric and threats against the US and South Korea.
It prohibits North Korea from conducting any transactions using US dollars, restricting the regime's ability to do business overseas.
It said North Korea would find and "mercilessly destroy" the terrorists.
With these comments, North Korea is essentially a petulant child talking back to its parents - after China basically gave the classic parental line, "Because I said so".
Beijing and Pyongyang have a relationship forged in the blood of the Korean War, and the Asian giant remains its wayward neighbour's main provider of aid and trade.
Analysts concur that a possible suspension of China's oil exports would have a major impact on North Korea, but they are more inclined to believe that China would not use its biggest punitive measure as leverage over North Korea-a total oil embargo-if Pyongyang is carrying out low-intensity provocations.
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.
