North Korea has threatened to launch an "unimaginable" strike on the US, accusing the Trump administration and its South Korean "puppet" allies of seeking to "ignite a war on the Korean peninsula at any cost".
The statement released by the Korean Central News Agency, Pyongyang's official's mouthpiece, predicted "imminent catastrophic disaster" in the region.
It vowed to "mercilessly smash the war frenzy of the US and South Korean puppet warmongers to get rid of the abyss of ruin through dangerous war gambling and inflict the most miserable death on the invaders".
The threat came in response to joint US-South Korea military drills in waters east of the Korean peninsula involving the USS Ronald Reagan, a nuclear powered aircraft carrier.
Forty warships have been deployed in a line stretching from the Yellow Sea to the Sea of Japan.
The presence of the US Navy's biggest warship in Asia comes ahead of Donald Trump's first official visit to the region, set to start in Japan on 5 November.
