US President Donald Trump has issued an extraordinary ultimatum to North Korea, warning the country not to make any more threats against the US or it will "face fire and fury like the world has never seen".

 

"North Korea best not make any more threats to the United States. They will be met with fire and fury like the world has never seen... he has been very threatening beyond a normal state. They will be met with fire, fury and frankly power the likes of which this world has never seen before," CNN quoted him as saying during a photo op at the Trump National Golf Club in Bedminster, New Jersey.

 

Trump's harsh words come as US intelligence analysts have assessed that North Korea has produced a miniaturised nuclear warhead, according to multiple sources familiar with the analysis of North Korea's missile and nuclear program.

 

North Korea has long maintained it wants nuclear weapons and long-range missiles in order to deter the US from attempting to overthrow the regime of Kim Jong Un.

 

It is not believed that the capability has been tested, according to the sources.

 

Earlier on Tuesday, President Trump was quick to highlight his administration's success in leading the UN Security Council to unanimously pass sanctions on North Korea.

 

"After many years of failure,countries are coming together to finally address the dangers posed by North Korea. We must be tough & decisive!" Trump wrote in a tweet on Tuesday morning.
