North Korean leader calls Trump 'dotard', threatens to tame him with fire

North Korean leader, Kim Jong Un has described US president Donald Trump as "deranged" and warned that it could test a powerful nuclear weapon over the Pacific Ocean in response to Trump's threats of military action, the country's foreign minister said on Friday.

Trump signed an executive order on Thursday boosting the United States' ability to sanction foreign banks, individuals and companies that facilitate trade with North Korea.

The move "will cut off sources of revenue that fund the countyr's efforts to develop the deadliest weapons known to humankind," Trump said on the sidelines of the UN General Assembly in New York.

Responding to Trump's address at the UN on Tuesday in which he threatened to "totally destroy" North Korea if it attacked the US or its allies, Kim Jong Un issued a counter statement on Friday describing the speech as "unprecedented rude nonsense."

According to Kim, Trump's "mentally deranged behaviour" and his threat to "totally destroy" North Korea "convinced me ... that the path I chose is correct and that is the one I have to follow to the last."

Kim said Trump would "pay dearly" and after his "ferocious declaration" of war, North Korea country would consider a "corresponding, highest level of hard-line countermeasure."

I will surely and definitely tame the mentally deranged US dotard with fire, he said.

When asked by reporters in New York what the countermeasure could be, North Korean Foreign Minister Ri Yong Ho said:

It could be the most powerful detonation of an H-bomb in the Pacific.

We have no idea about what actions could be taken as it will be ordered by leader Kim Jong Un," Ri added, according to South Korea's Yonhap news agency.

The international community has increased on North Korea over a series of recent missile and nuclear tests, and the issue has been a major point of discussion at the UN General Assembly.
