South Korea dismisses media reports of coup in DPRK as untrue

South Korea's spy agency said Sunday media reports of the North Korean leader's sister succeeding coup against her brother are not true at all, Report informs, citing foreign media.

The National Intelligence Service (NIS) dismissed reports that claimed Kim Yo-jong ousted North Korean leader Kim Jong-un after a coup. A separate government official also said such reports are not true.

Citing a report from US-based tabloid "Globe," some news outlets here said Kim Yo-jong staged a coup between May 6 and June 5 and removed Kim Jong-un from the post.

The report claimed Kim Jong-un at recent events is actually an impostor, pointing out that his appearance is different from the past, with substantial weight loss.

Speculations about Kim Jong-un's well-being have been brought up by the media regularly since last year. In July, the NIS dismissed rumors over Kim Jong-un's health problems as "groundless."

Earlier this month, the North Korean leader attended a defense development exhibition in Pyongyang and called for boosting military capabilities. According to photos released by the North, he was also seen smoking cigarettes with officials at the event.
