ianare writes: A propaganda video from the North Korean authorities has been removed from YouTube following a copyright claim by games maker Activision. It shows a space craft flying around the world and eventually over a city resembling New York. The buildings are then seen crumbling amid fires and missile attacks. However, the dramatic images were soon recognised as having been lifted from Call of Duty: Modern Warfare 3. By Tuesday, the video had been blocked, with a message notifying users of Activision's complaint shown in its place.
