Although prepared for "the enveloping fire at Guam", the North said it would watch what "the foolish Yankees" do before taking a decision.

Last week's threat against Guam escalated the sharp rhetoric being exchanged between the two sides.

This latest report points to a pause in the increasingly bitter war of words.

South Korea's President Moon Jae-in meanwhile has urged the US not to launch an attack on the Korean peninsula without its consent, saying "no one may decide to take military action without the consent" of the South.

What does North Korea's statement really mean?

The report on state news agency KCNA said Kim Jong-un "examined the plan for a long time" and discussed it with senior military officials.

The commander of North Korea's strategic force was now merely waiting for orders "after rounding off the preparations for the enveloping fire at Guam".

But, crucially, the report also said that Mr Kim would watch the US before making any decision, signalling an apparent deceleration in the provocative rhetoric.

Correspondents say that after days of menacing threats it might seem that Kim Jong-un could be in the mood to finally hit the pause button - but in a nation as secretive as North Korea, one can never be sure.

Analysts say it could simply mean Pyongyang is not fully ready to launch an attack on Guam, so it could just be buying more time.

What are North Korea's neighbours saying?

South Korea and China - North Korea's closest ally - have been urging calm and a renewed push for diplomatic resolutions.

On Tuesday South Korean President Moon Jae-in said the US should not act unilaterally. The two countries' defence agreement states that they must "consult together" when either is threatened.
