President Donald Trump has offered a harrowing ultimatum to North Korea if the country continues to threaten the United States.

Speaking during a 'working vacation' at his New Jersey golf club he said that any future escalation in tensions by Kim Jong-un would be met with 'fire and fury like the world has never seen'.

Trump said: "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 statement. As I said, they will be met with fire and fury and, frankly, power, the likes of which this world has never seen before."

His comments come following revelations that Pyongyang has successfully created a miniaturized nuclear weapon designed to fit inside its missiles.

As Pyongyang's continues a series of missile and nuclear tests in defiance of U.N. sanctions, it warned of a threat posed by North Korea's weapons programmes.

Japan released its annual Defence White Paper after North Korea fired two intercontinental ballistic missiles (ICBMs) last month on lofted trajectories to land off Japan's west coast.

"It is conceivable that North Korea's nuclear weapons programme has already considerably advanced and it is possible that North Korea has already achieved the miniaturisation of nuclear weapons and has acquired nuclear warheads," Japan's Defence Ministry said.

After the UN imposed it's latest sanctions on the totalitarian state, North Korea said it would bring 'thousands-fold' revenge against the US.

Yesterday during a ceremony marking 72 years since the bombing at Hiroshima, Japanese Prime Minister Shinzo Abe called for 'a world free of nuclear weapons'.

"This hell is not a thing of the past," Hiroshima Mayor Kazumi Matsui said at Sunday's commemoration ceremony, reports The Independent.

"As long as nuclear weapons exist and policymakers threaten their use, their horror could leap into our present at any moment.

"You could find yourself suffering their cruelty."

The sombre ceremony marked more than seven decades since an atomic bomb was dropped on the Japanese city near the end of World War 2.
