Kim Jong Un Is Alive And Well- South Korean Presidential Aide

North Korean leader Kim Jong Un is “alive and well,” according to an aide to the president of neighboring South Korea.

Rumors have swirled regarding Kim’s health after he missed the celebration of his late grandfather’s 108th birthday. The event commemorates the birthday of Kim Il Sung, the founder of North Korea and is one of the most important dates in the country’s calendar.

Kim hadn’t missed the April 15 event since he assumed power in 2011 following his father Kim Jong Il’s death, according to The Associated Press. He was still nowhere to be seen on Saturday as his country commemorated Military Foundation Day.

While North Korea’s state media has remained silent about Kim’s health and whereabouts, some media outlets have reported that he was recovering from surgery.

But on Sunday, Chung-in Moon, a foreign policy advisor to South Korea’s president Moon Jae-in, told Fox News: “Our government position is firm. Kim Jong Un is alive and well.” The aide said Kim has been staying in the Wonsan area since April 13, adding: “No suspicious movements have so far been detected.”

It comes as 38 North, a website that specializes in news about North Korea, reported that satellite images show a train that likely belongs to Kim has been parked at the Leadership Railway Station servicing his Wonsan compound since at least April 21.

Kim hasn’t been seen in public since April 11, but South Korean officials have questioned reports about the North Korean leader’s health, saying that no unusual activity has been detected in the North, according to Reuters.

U.S. intelligence officials have also said they see no sign of unusual military activity that would suggest something was amiss.
