Washington/Seoul, May 4 (TIWN) US President Donald Trump said that he was glad to see North Korean leader Kim Jong-un "back and well" following rumours he the latter was gravely ill, the media reported on Sunday.

CNN has reached out to the White House for additional information about the President's tweet and whether the White House has authenticated the photos released by North Korean state media. A US official told CNN that the current analysis from multiple threads of intelligence is that the photos published in the last 24 hours by North Korean state media showing Kim at a fertilizer plant opening are legitimate. On Sunday, South Korean presidential adviser Moon Chung-in told CNN that the North Korean leader was "alive and well" despite speculation about his health. The adviser to South Korean President Moon Jae-in said Kim had been staying in the Wonsan area, on the country's east coast, since April 13, adding: "No suspicious movements have so far been detected."
