North Korea has said it is considering carrying out missile strikes on the US Pacific territory of Guam.
The report in state media, quoting an earlier military statement, came hours after President Donald Trump threatened North Korea with “fire and fury”.
The North’s official news agency said it was considering a plan to fire medium-to-long-range rockets at Guam, where US strategic bombers are based.
The exchanges mark a sharp rise in rhetoric between the two countries.
The UN recently approved further economic sanctions on North Korea, which Pyongyang said were a “violent violation of our sovereignty”, warning the US would “pay a price”.
On Wednesday, the official KCNA news agency said North Korea was “carefully examining the operational plan for making an enveloping fire at the areas around Guam” using its domestically made medium-to-long-range Hwasong-12 missiles.
The news agency reported a military statement issued on Tuesday, which probably came in response to US military drills in Guam.
In a message to the public, the governor of Guam Eddie Baza Calvo said there was currently “no threat” to the island and the Marianas archipelago, but that Guam was “prepared for any eventuality”.
North Korea’s statement is the latest stage in a heating up of rhetoric and tension.
Pyongyang, which has tested nuclear devices five times, launched two intercontinental ballistic missiles (ICBM) in July, claiming it now had the ability to hit the mainland US.
On Tuesday, media reports in the US claimed the North had achieved its goal of making a nuclear warhead small enough to fit inside its missiles.
