It is being described as further confirmation of the rise of the young man reportedly being groomed as the next leader of North Korea.
Rare images have emerged of the secretive state’s ailing leader Kim Jong-il alongside his son Kim Jong-un, who is thought to be in his late 20s.
The young man was this week appointed to senior political and military positions.
The latest pictures were taken at celebrations to mark the 65th anniversary of the founding of the ruling Workers’ Party.
Kim Jong-un is the North Korean leader’s third son, but until his recent appointments he had never before been talked about in the state media.
