North Korea Dictator Kim Jong-un Reportedly Dead After Botched Heart Surgery - TMZ

North Korea's Supreme Leader/dictator Kim Jong-un has reportedly died, or is on his death bed with no hope for recuperation -- according to media outlets in China and Japan.

Amid reports China has sent a medical team to their communist neighbors this week to check in/advise on Kim, a Hong Kong-backed news channel's vice director -- who's apparently the niece of a Chinese foreign minister -- blasted out the news herself ... he's dead. TMZ has not confirmed that.
