The North Korean tyrant has shown he does not tolerate failure after he had Kim Hyok-chol and others were killed on his orders.
unnamed sources spoke to South Korean media over the executions, which are understood to have happened in March – one month after the doomed Trump-Kim summit in Vietnam.
Kim Yong-chol, a senior who also attempted to thrash out a deal with the US, was sent to a forced labour camp.
The source said: “Kim Hyok-chol was investigated and executed at Mirim airport with four foreign ministry officials in March.”
It was reported that Kim launched the purge to bring a swift end to any hint at internal rebellion against his harsh leadership.
North Korea has not directly addressed the claims made and has previously denied carrying out brutal executions.
But, state mouthpiece Rodong Sinmun said on Thursday: “Acting like one is revering the leader in front of others but dreaming of something else when one turns around is an anti-party, anti-revolutionary act.
“It throws away the moral fidelity toward the leader, and such people will not avoid the stern judgement of the revolution.

“There are traitors and turncoats who only memorise words of loyalty toward the leader and even change according to the trend of the time.”
It is not the first time that Kim has ordered the deaths of his officials.
Last year, Hyon Yong-chol – Kim’s former defence chief, was reportedly executed with an anti-aircraft gun for disrespecting the leader by napping during a rally.
Kim also ordered the execution of Ri Yong-jin, an education official, for falling asleep at a meeting led by the tyrant.
