North Korean leader Kim Jong-un has appeared in public with a bandage on his right wrist in the latest health mystery since his 40-day disappearance.

Kim Jong-un, 32, was spotted with a bandage on his right hand during a recent inspection of a weapons factory in Pyongyang.

He waved and smiled at supporters in the video on North Korean Central TV, seemingly unaffected by the injury.

A South Korean government official said: “He didn’t have the injury when he inspected a military unit on April 4.

“So it must be recent.”

The source of Kim Jong-un’s injury remains unclear.

Rumors around Kim Jong-un’s health ran riot last year after he failed to appear in public for 40 days without explanation.
