"We have already warned several times that we will take counteractions for self-defence including a salvo of missiles into waters near the US territory of Guam, an advance base for invading the DPRK, where key US bases are located, as the US has resorted to military actions in sensitive regions, making the waters off the Korean peninsula and in the Pacific restless," the statement reads.
"The US military action hardens our determination that the US should be tamed with fire and lets us take our hand closer to 'trigger' for taking the toughest countermeasure."
Pyonyang has previously threatened to "bracket with fire" the US Guam territory, by launching four of its intermediate ballistic missiles into the sea close to the collection of attols.
The remote Pacific Islands have a population of about 160,000.
The threat came among a flurry of North Korean state media publications asserting its new-found nuclear power.
"The US and its vassal forces make desperate efforts to block the advance of the DPRK as they are frightened by the high spirit and rapid advance of (Pyonyang) dashing ahead toward the final goal of rounding off the state nuclear force," one article in North Korean official Central Committee newspaper Rodong Sinmun asserts.
Another KCNA article threatens Japan, which has been undertaking joint manoeuvres with the USS Ronald Reagan near the Korean Peninsula.
"The DPRK's toughest counteractions include a warning not only to the US, which gravely threatens the former's rights to sovereignty and existence, but also to Japan which acts rashly, toeing the US line, without knowing what would happen to itself. Japan had better consider the DPRK's warning carefully."
