As of now, it is Mr. Kim's younger sister, Kim Yo-jong, who is seen as a potential successor.
The incident came amid stalled inter-Korean relations and one day after the North ended mounting rumors about leader Kim Jong-un's health and whereabouts by reporting his first public appearance in almost three weeks. He was reportedly last seen on state media on April 11. Other reports said that China had sent doctors to Pyongyang to save him.
"All the participants again burst into thunderous cheers of "hurrah", the NYT reports that the Korean Centra News Agency said in a release.
Robert E Kelly, Professor of Political Science at Pusan National University, in South Korea, said: "The kind of speculation we've seen in the last few weeks is going to continue until we see him live somewhere".
The South Korean authorities made it clear that the incident is in violation of the bilateral military accord of the Comprehensive Military Agreement signed in September 2018, and urged the North to fully abide by the agreement.
Where it stands: Photos from the ceremony have not been released, AP reports, and Kim's appearance has not been independently verified. But until Saturday, it had gone weeks without reporting any public appearances by its leader or responding to the speculation about his health, and its silence fueled the rumor mill.

Daily NK, a South Korean website which bases its stories on accounts by defectors from the North, cited an unidentified source inside DPRK on 20 April as claiming that Kim was recovering from a heart surgery allegedly conducted a week prior because of his "excessive smoking, obesity, and fatigue".
His absence sparked rumors over his health, including speculation he had died or was brain-dead, raising concerns over what would happen in the nuclear-armed country in the event of the sudden demise of its third-generation hereditary leader.
His second public visit this year to the site 50km north of the capital, Pyongyang, included a sizeable audience of officials from the army, the ruling Workers' Party of Korea and the local community. "Yes, I do have a very good idea, but I can't talk about it now", said Trump when asked at a news conference if he had been given an update on the North Korean leader.

Reporting from inside the isolated North is notoriously hard, especially in connection with its leadership, which is among its most closely guarded secrets. But most have turned out to be groundless.
