The leader's recent absence from public events had triggered a series of fevered rumours and unconfirmed reports over his health condition
Seoul: North Korea's Kim Jong Un has made his first public appearance in nearly three weeks, state media reported Saturday, following intense speculation that the leader of the nuclear-armed nation was seriously ill or possibly dead.
The North reported that Kim had attended the opening of a fertiliser factory and released pictures it said showed the leader cutting a ribbon at the ceremony on Friday in Sunchon, north of Pyongyang, although the appearance could not be verified.
Rumours about Kim's health have been swirling since his conspicuous no-show at April 15 celebrations for the birthday of his grandfather, the North's founder -- the most important day in the country's political calendar.
His absence triggered a series of fevered rumours and unconfirmed reports over his condition, while the United States and South Korea insisted they had no information to believe any of the conjecture was true.
His sudden death would have left Pyongyang facing an unplanned succession for the first time in its history and raised unanswered questions over who would succeed him and take over the North's nuclear arsenal.
The Korean Central news agency said that onlookers "broke into thunderous cheers of 'hurrah!'" when Kim appeared.
The pictures released by the Rodong Sinmun newspaper showed Kim in his trademark black suit, smiling broadly as he looked around the factory.
He was flanked by senior officials -- including his sister and close adviser Kim Yo Jong -- and showed no outward signs of ill health.
As with previous pictures released by the North during the global coronavirus pandemic, Kim was not wearing a mask, unlike the hundreds of workers cheering for him and releasing balloons.
Analysts said Kim could not appear in public wearing a mask as it would make him appear vulnerable to the North Korean people.
The North has insisted that it has not seen a single case of coronavirus, although experts say it is unlikely.
Kim's repeated appearances without a mask had led some to speculate that he may have caught the virus.
Reporting from inside the isolated North is notoriously difficult, especially on matters relating to its leadership, which is among its most closely guarded secrets.
Rumours of ill health
The North Korean leader had not made a public appearance since presiding over a Workers' Party politburo meeting on April 11, and the following day state media reported that he had inspected fighter jets.
Daily NK, an online media outlet run mostly by North Korean defectors, had reported that Kim was undergoing treatment after a cardiovascular procedure last month.
Citing an unidentified source inside the country, it said Kim -- who is in his mid-30s -- had needed urgent treatment due to heavy smoking, obesity and fatigue.
Soon afterwards, CNN reported that Washington was "monitoring intelligence" that Kim was in "grave danger" after undergoing surgery, quoting an anonymous US official.
Officials in Seoul had consistently downplayed the reports and a presidential security advisor said that Kim was "alive and well" and staying in the eastern resort town of Wonsan.
Leif-Eric Easley, a professor of international studies at Ewha University in Seoul said Kim's disappearance had highlighted that the world was "largely unprepared for instability in North Korea".
"Washington, Seoul and Tokyo need tighter coordination on contingency plans," he said.
Rachel Lee, a former US government North Korea analyst, told AFP that the past weeks had also shown the "insatiable appetite for news about the North Korean leadership".
She highlighted the "potential regional and international risks that come with Kim Jong Un's health" while lamenting the "poor analysis of North Korea that is based on impressions and speculation, not hard data".
US president Donald Trump suggested earlier this week that Washington believed Kim to be alive and well and declined to immediately comment on Kim's apparent re-emergence.
Trump and Kim have met three times, although talks on the North's nuclear capabilities have long been stalled with no sign of them resuming.
Previous absences from the public eye on Kim's part have also prompted speculation about his health. The North is extremely secretive, especially about its leadership.
Kim's father and predecessor had been dead for two days before anyone outside the innermost circles of North Korean leadership was any the wiser.
In 2014, Kim Jong Un dropped out of sight for nearly six weeks before reappearing with a cane. Days later, the South's spy agency said he had undergone surgery to remove a cyst from his ankle.
