North Korea has released its latest propaganda video showing a US aircraft carrier being blown up as it warned the US against carrying out military action.

The clip was released at the weekend when it conducted a ground test of a new type of high-thrust rocket engine that leader Kim Jong-un called a revolutionary breakthrough for the country's space programme.

Displaying images taken from its own recent ballistic missile launches and US/South Korean military exercises, it then shows a superimposed image of the USS Carl Vinson on fire, with the warning: “A knife will be stabbed into the throat of the carrier.”
