North Korean state media released images of the country's leader, Kim Jong Un, making his first public appearance after weeks of speculation about his health and whereabouts.

Kim attended the completion ceremony of a fertilizer plant north of the capital, Pyongyang on Saturday, marking his first public appearance since April 11.

Rumors had circulated that Kim might be dead, but US and South Korean intelligence services expressed skepticism over such reports, the Washington Post reported in late April.

The North Korean leader's younger sister Kim Yo Jong joined her brother on the visit to the fertilizer plant, according to KCNA. She's the most powerful woman in North Korea, and it's speculated she would take over as the leader of the rogue state in the event of her brother's death.

South Korean Unification Minister Kim Yeon-chul recently suggested that concern over the coronavirus pandemic was likely to blame for Kim's lack of public appearances.

"He had never missed the anniversary for Kim Il Sung's birthday since he took power, but many anniversary events including celebrations and a banquet had been cancelled because of coronavirus concerns," the minister told a parliamentary hearing, per a Reuters report from Tuesday.

Kim's absence also prompted the suggestion that the leader may have been taking precautions against the coronavirus.

North Korea has implemented some measures to prevent the spread of the coronavirus, but claims that its has no confirmed cases as well as fatalities.

Satellite images released on April 29 showed a train usually used by the leader near a resort town, with people suggesting he may be staying there.

Adding to the speculation, a South Korean news outlet that specializes in reporting the secretive state said that Kim had undergone a cardiovascular procedure and was recovering, although this report was unconfirmed.

The rumors of his health started when Kim missed the annual birth-anniversary celebrations of his grandfather, state founder Kim Il Sung, on April 15. It is the country's most important holiday.
