S Korean National Intelligence Service Says 'No Signs' Kim Jong-un Received Heart Surgery

After weeks of Kim Jong Un's absence that caused speculations on his health, the North Korean leader reappeared in public on 1 May alive and well.

The National Intelligence Service of South Korea rejected the suggestions that Kim Jong-un had undergone heart surgery, saying that "Kim Jong-un's health abnormality is absurd" and there are "no signs of heart surgery", according to South Korean state-run news agency Yonhap.
Earlier on 1 May, Kim Jong-un appeared in public for the opening ceremony of a new fertilizer plant in Sunchon, finishing his almost month-long absence that caused speculations on his health. 
The rumours about Kim's "heart surgery" emerged in early April when the leader failed to attend the anniversary of his grandfather's birthday, fueled by the reports that he had undergone a heart surgery that put him in "grave danger".
At the time, a senior official at the South Korean presidency was cited by Yonhap as saying that Seoul believed that there was no evidence to suggest that the North Korean leader had undergone heart surgery, regardless of what media reports said.
