A bizarre propaganda video depicting an American city in ruins and engulfed in flames after a missile attack has been posted online by the North Korean regime as Pyongyang prepares for an ‘imminent’ nuclear test.

North Korea’s official website, Uriminzokkiri, on Saturday uploaded the video which shows a young man imagining himself aboard a North Korean space shuttle that circles the earth and then zooms in on a reunified Korea.

The dream sequence then switches focus to apocalyptic scenes of ruined skyscrapers, including what appears to be the Empire State building, in a city resembling New York. Reports have suggested the footage bears more than a striking resemblance to the Call of Duty video game.

“Somewhere in the United States, black clouds of smoke are billowing,” the caption reads. “It seems that the nest of wickedness is ablaze”.

The video ends with the young man concluding that his dream will “surely come true”.

“Despite all kinds of attempts by imperialists to isolate and crush us… never will anyone be able to stop the people marching toward a final victory,” it said.

An instrumental version of Michael Jackson’s “We Are the World” plays in the background throughout the three-and-a-half minute video.

The propaganda video came following threats from the reclusive state that it would retaliate against “US hostility” in defiance of UN Security Council sanctions over its rocket launch in December.
