US intelligence agencies are closely monitoring a report that Kim Jong Un is in “grave danger” following surgery.

According to the South Korea based Daily NK , the North Korean leader underwent a heart procedure on April 12th due to his “excessive smoking, obesity, and overwork.”

Speculation that Kim’s health was in question kicked off after he was absent from a celebration of his grandfather’s birthday on April 15th.

While the US calls these reports “credible,” officials admitted to CNN that they are hard to assess. South Korean sources told the news site that they cannot independently verify the claims either.
