Press TV - US President Donald Trump says North Korean leader Kim Jong-un "will be tested like never before," as the two leaders continue trading insults and Pyongyang threatened to test a hydrogen bomb over the Pacific Ocean.

"Kim Jong-un of North Korea, who is obviously a madman who doesn't mind starving or killing his people, will be tested like never before," Trump tweeted Friday.

Trump's latest insult came one day after he imposed additional sanctions on Pyongyang.

Trump also tweeted a number of messages complimenting his controversial UN speech.

Trump warned Kim in a speech to the UN General Assembly on Tuesday that the United States, if threatened, would “totally destroy” his country of 26 million people.

Relations between the US and North Korea have significantly deteriorated in recent months, with the two leaders stooping to trading personal insults.

Earlier on Friday, Kim said Trump is “deranged” and will “pay dearly” for threatening to destroy his country.



Trump signed an executive order on Thursday imposing new sanctions on North Korea.

Last month, when the standoff between North Korea and the US over Pyongyang’s ballistic missile and nuclear weapons programs reached its peak, Trump threatened Kim with “fire and fury the world has never seen.”

Trump’s threats to "totally destroy" North Korea is counterproductive and justify Pyongyang's nuclear weapons and missile programs that it insists are for self-defense, according to analysts.

Experts say Trump's speech could have an opposite effect, intensifying the deteriorating situation in the Korean peninsula.
