North Korea has released a video portraying a dream of an American city in flames.
The film, posted on the semi-official Uriminzokkiri website shows scenes reminiscent of the September 11 attacks in 2001.
It is part of a dream sequence in which a photographer circles the earth in a fictional North Korean space shuttle.
The rocket is labelled the Unha-9 and the satellite is the Kwangmyongsong-21, as the young man dreams of photographing the earth from space.
"Black smoke is seen somewhere in America. It seems that the nest of wickedness is ablaze with the fire it started," says the text of the video in Korean.
"My dream WILL come true. Despite all sorts of schemes of imperialists to isolate and oppress us, the Baekdu Mountain's strong country will be unified and grow strong. They will not be able to stop our journey toward the final victory," the video text reads later.
So far, North Korea has launched the Unha-3 rocket and is also on the third version of its satellite, which finally made it into space in December last year at the third attempt, triggering new sanctions from the United Nations (UN).
The North is banned by the UN from developing missile and nuclear technology but says that it has a sovereign right to a peaceful space programme.
North Korea has trailed plans to carry out a third nuclear test, which experts believe is imminent.
Washington has warned that a third test would trigger more sanctions against Pyongyang, but it took a conservative line on the latest agit-prop video from North Korea.
"I've seen it," State Department spokeswoman Victoria Nuland told a news conference in Washington, referring to the video that was released at the weekend. "I'm clearly not going to dignify it by speaking about it here."
