North Korea has posted a video on YouTube depicting an American city resembling New York engulfed in flames after an apparent missile attack, it emerged today.

The video was uploaded on YouTube by the North’s official website, Uriminzokkiri, which distributes news and propaganda from the state media, as the country prepares to conduct its third nuclear test.

The footage is shot as a dream sequence, with a young man seeing himself on board a North Korean space shuttle launched into orbit by the same type of rocket Pyongyang successfully tested in December.

As the shuttle circles the globe – to the tune of We Are the World – the video zooms in on countries below, including a joyfully re-unified Korea.

In contrast, the focus then switches to a city – shrouded in the U.S. flag – under apparent missile attack with its skyscrapers, including what appears to be the Empire State Building, either on fire or in ruins.

“Somewhere in the United States, black clouds of smoke are billowing,” runs the caption across the screen.

“It seems that the nest of wickedness is ablaze with the fire started by itself,” it added.

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.

The video emerged as South Korea’s U.N. ambassador said today that a North Korean nuclear test “seems to be imminent”.

The North is expected to conduct its nuclear test as a defiant response to UN sanctions imposed after its December rocket launch.

It comes at a time of tension resulting from North Korea’s announcement that it would carry out more rocket launches and nuclear test after it was censured by the United Nations Security Council over the launch of a rocket in December.

North Korea declared a boycott of all dialogue aimed at ending its nuclear programme.

Ambassador Kim Sook said there are “very busy activities” taking place at North Korea’s nuclear test site “and everybody’s watching”.

Kim Sook told a press conference that in the event of a nuclear test, he expects the U.N. Security Council to respond with “firm and strong measures”.

North Korea announced last month that it would conduct a nuclear test to protest Security Council sanctions toughened after a satellite launch in December that the U.S. and others say was a disguised test of banned missile technology.

The council ordered North Korea in the sanctions resolution to refrain from a nuclear test or face “significant action”.

South Korea joined the Security Council in January and holds the rotating presidency this month. Kim Sook said he was speaking as South Korea’s ambassador, not as the council president.

He said that during negotiations on the latest sanctions resolution all 15 council members – including North Korean ally China – were unified.

“They are very firm and resolute and I would expect very firm and strong measures to be taken in terms of format as well as in substance once they go ahead with such provocation as a nuclear test,” Kim Sook said.

Pyongyang’s two previous nuclear tests, in 2006 and 2009, both occurred after it was condemned by the United Nations for rocket launches.

The sanctions, aimed at trying to derail the country’s rogue nuclear weapons and ballistic missile programs, bar North Korea from testing or using nuclear or ballistic missile technology, and from importing or exporting material for these programs.

The latest sanctions resolution again demanded that North Korea abandon its nuclear weapons program and cease launches.

It slapped sanctions on North Korean companies and government agencies, including its space agency and several individuals.
