In the July video footage, released late on Thursday, the speaker said “the marshal, despite health problems, continues, like the flame flow, keeping the path of leading the nation,” the report said.
This summer, the Pyongyang television has at least twice shown the young leader, in his early 30s, walking with a limp. However, this is the first open mentioning of Kim Jong-un’s possible health problems.
Health rumors swirl around Kim Jong-un as he has failed to appear in public since September 3.
The North Korean leader, named the world's 46th most powerful person by Forbes Magazine last year, was also absent from a major political meeting in Pyongyang, the session of the Supreme People’s Assembly, on Thursday.
Since he took power in December 2011, Kim Jong-un has participated in all the four sessions of the Supreme People’s Assembly, the unicameral legislature of the Democratic People's Republic of Korea (DPRK).
