Just when it seemed the rumor mill over North Korean leader Kim Jong Un’s health had stopped churning, a new set of claims appeared in various news outlets over the past week. The latest claims are that Kim Jong Un is in a coma and that he has partly transferred power to his sister, Kim Yo Jong.

The new round of reporting started on Aug. 20, with news that the South Korean National Intelligence Service (NIS) believed Kim had recently delegated authority to Kim Yo Jong and other top officials. But the source of that information was not revealed, and details were lost along the way in some media outlets' coverage.
