An enraged North Korea has apparently threatened to kill authors of a report claiming its young leader used Adolf Hitler’s memoir as a leadership guide for his regime.

North Korea vehemently denied the report from a news website run by North Korean defectors which said Kim Jong-Un gave out copies of “Mein Kampf” to senior officials on his birthday and urged them to study it as a leadership skills manual, reports AFP.

Kim ordered an in depth study on the Third Reich and believed North Korea should draw lessons and practical applications from it, news portal New Focus International said in the report, citing an unnamed North Korean official working in China.

The North’s Ministry of People’s Security issued an angry response Wednesday, dismissing the report as a “smear campaign” written by “a handful of human scum … moving desperately to deter North Korea’s progress”.

The ministry was determined to “physically remove the despicable human scum who are committing treason,” according to a statement carried by the official Korean Central News Agency.

It also vowed to launch “merciless punishment of justice” against Seoul and Washington, accusing the two nations of encouraging the defectors to defame its ruler.
