North Korean Leader Kim Jong Un Reappears — at Fertilizer PlantAfter a wave of news reports that he was gravely sick or even dead, North Korean leader Kim Jong Un reappeared in public Saturday — for the first time in 21 days — at a fertilizer factory. North Korean state radio said Kim attended the completion ceremony for a phosphate fertilizer plant in Sunchon, a city north of the capital, Pyongyang. Rumors about Kim's health began to swirl after he skipped a major political North Korean political anniversary April 15. The reason he did not attend is still unclear. The Daily NK, a Seoul-based website, reported that he was recovering from heart surgery. Several U.S. media said the U.S. had been monitoring intelligence he was in grave danger.
