The beheaded body of North Korean leader Kim Jong-un’s uncle has been exposed to be seen by senior Pyongyang regime officials, US President Donald Trump said in a new book, AFP reported on Friday.

“He killed his uncle and placed his body on the stairs” of an official building, Donald Trump told investigative journalist Bob Woodward.

“His head was cut off and put on his chest,” the US president continued, according to excerpts from the book that AFP was able to consult.

Jang Song-thaek, the North Korean leader’s uncle by alliance, then considered the regime’s number two, was executed in December 2013, officially because he “betrayed the nation.”

North Korea has never said how Jang Song-thaek was executed, several versions, all extremely atrocious and often contradictory, circulating in the media.

The version of the American president – who seems to have wanted to show his closeness to the North Korean leader – is the first to refer to a beheading of Kim Jong-un’s alliance by alliance.

Kim “tells me everything. He told me everything,” says the US president in this book, which is a sequel to the book “Fear. Trump at the White House,” published by Woodward in 2018.

Investigative journalist Bob Woodward received 25 letters “never made public before,” written by the two leaders, according to the American publishing house Simon & Schuster.

In their letters, “Kim describes the connection between the two leaders as worthy of a ‘fantastic film’, while the leaders embark on an extraordinary diplomatic minuet,” the editor said on the Amazon’s book page.

Donald Trump and Kim Jong-un have met three times, the first time at a historic summit in June 2018 in Singapore.

However, negotiations on North Korea’s denuclearization have not progressed at all and are at a standstill after the failure of the second summit, in February 2019, in Hanoi.

Bob Woodward is known for his revelations about the Watergate affair, which led to the resignation of President Richard Nixon in 1974.
