North Korea has said it is considering a missile strike on the US territory of Guam.

Responding to the US president Donald Trump's contribution to a ramping up of rhetoric between him and the rogue state, a spokesman for North Korean army is "carefully examining" a plan to strike.

It follows Trump's statement that any threat to the US would be met with "fire and fury".

A spokesman for the Korean People's Army said that when Kim Jong Un makes a decision, the strike plan against Guam will be "put into practice in a multi-current and consecutive way any moment" adding that "enveloping fire" would contain major US military bases on the island territory.

The territory has a population of around 160,000 and is located in the western Pacific Ocean and includes the Anderson Air Force Base.

On Tuesday (8 August), the Washington Post reported how North Korea could fit nuclear warheads inside one of its missiles, to which Trump replied: "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".

A North Korea expert, who asked not to be named, told Sky News that Pyongyang is "a lot more than halfway" to producing a nuclear weapon capable of exploding above the US.

"It's fair to say it's just a matter of time, in terms of being able to hit the hit the US with a (nuclear) missile."
