NORTH KOREA'S supreme leader Kim Jong-un's armoured train has been spotted at one of his palaces, casting in doubt reports that he has died and creating speculation that he could be seen in public again soon.

Most of the despotic leader's palaces are directly accessible via private rail lines leading to the front porch of each luxurious edifice. The monitoring project, 38 North, said in its report on Saturday the train possibly containing Kim Jong-Un was parked at the "leadership station" in Wonsan on April 21 and April 23.

However, the report stressed: "The train's presence does not prove the whereabouts of the North Korean leader or indicate anything about his health but it does lend weight to reports that Kim is staying at an elite area on the country's eastern coast."
