The headless body of Kim Jong Un’s executed uncle was displayed to senior North Korean officials, U.S. President Donald Trump told the author of an upcoming book on the U.S. president, Afp reported on 12 September 2020.
Jang Song Thaek, the North Korean leader’s uncle by marriage and a hugely powerful figure within the regime, was purged for treason and corruption in 2013, in what was widely seen as Kim mercilessly asserting his authority.
Kim “tells me everything. Told me everything,” Trump told Washington Post investigative journalist Bob Woodward, according to his forthcoming book “Rage.”
“He killed his uncle and he put the body right in the steps,” Trump said, in an apparent reference to a building used by senior officials.
“And the head was cut, sitting on the chest,” he added in excerpts from the book seen by AFP.
The North has never officially stated how Jang was executed, although multiple reports say an anti-aircraft gun was used.
Trump’s account — apparently intended as a demonstration of the closeness of his relationship with Kim — is the first from any senior official to mention decapitation.
