A White House statement said Trump and President Emmanuel Macron had discussed "the increasingly unsafe situation associated with North Korea's destabilising and escalatory behaviour".

Washington and Pyongyang have recently been exchanging sharp statements.

Earlier in the day, Trump issued his sternest warning yet, saying the military is "locked and loaded" to respond to any provocation from North Korea .

Asked Friday if the USA was going to war, he said cryptically, "I think you know the answer to that".

This was revealed after a Defense Intelligence Agency report indicated that the country has manufactured a miniaturized nuclear warhead which can fit inside long-range missiles capable of reaching that continental United States.

"I think he's made a decision long ago, quite frankly, to try to negotiate the threat with North Korea".

Prime Minister Shinzo Abe says he will do everything he can to protect the Japanese people as tensions escalate over North Korean plans to send missiles flying over Japan toward Guam.

China has proposed on several occasions a "double moratorium": the off simultaneous nuclear tests and ballistic north Korean and joint military exercises Washington and Seoul. Just as we reach the 72nd anniversary of the nuclear bombings of Hiroshima and Nagasaki, Trump is making thinly veiled threats to again use USA nuclear weapons if North Korea continues the same behavior.

In Moscow, the head of Russian diplomacy Sergei Lavrov said on Friday "very concerned" about the risk of conflict "very high" between United States and North Korea.

An official from the White House indicated that it was not necessary to see in the president's remarks the sign of a military action is imminent. "There is nothing new", he said on condition of anonymity.

The Pentagon now has 28 500 troops in the south of the 38th parallel.
