NORTH Korea has threatened to nuke the White House and reduce it to ashes as Kim Jong-un's regime bragged the days of the US are now "over".

In a punchy editorial published by the state media agency KNCA, Pyongyang slammed President Donald Trump's decision to dispatch its naval fleet to the Korean Peninsula.

And it went on to vow it will be victorious over an enemy made up of "murderous ogres", "robbers", "air pirates" and "warriors who master the occult arts", reports the Express.

North Korea's military commander said the White House would be "reduced to ashes", as the editorial claimed the US was planning to destroy Pyongyang.

The editorial read: "This is a stern warning to the US imperialists and their stooges running amuck for aggression and war moves.

"The world will clearly witness how the crime-woven history of the US imperialists will be over, how the despicable remaining days of the south Korean puppet forces will come to an end and how national reunification, the cherished desire of the Korean nation, will be achieved."
