Doubts about Kim Jong Un, The Sun: Here's the guy in the coffin.

In some media, meanwhile, there has been a viral photo showing a person similar to Kim Jong Un in a glass coffin.

The picture, however, does not belong to Kim Jon Un. As reports British media The Sun, the image was realized in 2011 at the funeral of Kim Jong-il, who passed away from a heart attack. Initially, the photograph was published by Japanese media HKSTV and later distributed by other foreign media.

Speculations about Kim Jong Un's state of health began after missing his grandfather's birthday celebration on April 15th. Kim, who is 36, has not been seen in public since 11 April.
