Tensions between the US and North Korea are said to be the most serious threat to world peace.
The US ambassador to the UN told an emergency Security Council meeting North Korea is “begging for war” and called for “the strongest possible measures”.
President Donald Trump has threatened military action and warned North Korea it faces “total annihilation” if it threatens the US or its allies Japan and South Korea.
But defiant Kim Jong-un threatened America with a “miserable end” as he reportedly moved a ballistic missile to the west coast ready for another test launch.
He has previously threatened to launch rockets at US Pacific island Guam and moved fighter jets to the coast to intercept US bombers after accusing Trump of declaring war.
