North Korea have been increasing their nuclear missiles tests over the past few months and a defected diplomat has warned of the danger of Kim Jong-un amid World War 3 scares.
Thae Yong-ho, who was North Korea’s deputy ambassador to the United Kingdom, said he left the hermit kingdom because he was treated like a “modern slave”.
Speaking to CNN, Mr Thae explained that Kim Jong-un was under pressure and was forced to show how merciless he was.
He said: “It’s a little bit complicated but mainly I did not want for my sons to live a life like me, which is nothing but a modern slave.”
When asked about some of his family who still live in North Korea, Mr Thae said he is “not quite sure what will happen now”.
Mr Thae explained that Kim Jong-un was under pressure during parts of his reign as the leader of the state.
He said: “He faced some challenges inside the leadership of North Korea.
“That’s why Kim Jong-un decided to show he is a man with mercilessness – so that everyone should be frightened about him.”
Mr Thae finished by insisting that his sons were happy with his decision to defect from North Korea.
“When they heard my decision then they were very happy, and they really appreciated that I decided to let them free,” he said.
Kim Jong-un has ramped up his nuclear missile tests over recent months following his “war of words” with President Donald Trump.
The hermit kingdom’s most recent test was its most powerful, taking place on September 3 at the Punggye-ri Test Site and registered as a 5.7 magnitude earthquake by the South Korean Government.
It was reported that a tunnel collapse in North Korea left 200 workers dead at the Punggye-ri testing facility at some point after the sixth test in September.
A senior diplomat continued the threats towards the US after Pyongyang warned the United States to take the threat of a possible atmospheric nuclear test over the Pacific Ocean should be taken “literally”.
Donald Trump is set to travel to Asia in a bid to urge countries to continue applying pressure on the North Korea and its nuclear programmes.
The US has deployed nuclear bombers to the Pacific ahead of the Asia tour.
