Adolph Hitler's remains were burned and dumped in an East German river in 1970 on orders from the head of the KGB, according to a report out of Russia this week.

In an interview with Russia's Interfax news agency, Gen. Vasily Khristoforov, the head archivist of Russia's Federal Security Service (FSB), discussed previously-secret documents that detailed the events that led to the final destruction of Hitler's bones.

Khristoforov said according to the documents, the top secret operation to burn and dump Hitler's body - as well as the remains of his wife, Eva Braun, Nazi propaganda chief Joseph Goebbels, and Goebbels' entire family - was planned to ensure the graves would never be places of gathering for Nazi sympathizers.

According to Khristoforov, the bodies had been buried at a Soviet military base in Magdeburg in East Germany since 1946. When the garrison was to be handed over to East German authorities in the spring of 1970, KGB chief Yuri Andropov decided to destroy the bones rather than move them.

"The remains were burnt on a bonfire outside the town of Shoenebeck, 11 kilometers away from Magdeburg, then ground into ashes, collected and thrown into the Biederitz River," a document reads, according to Khristoforov.

According to historians, Hitler committed suicide on April 30, 1945, when the Soviet Army entered Berlin.

Khristoforov said that fragments of Hitler's jawbone and skull were spared from the bonfire and are still are kept in Moscow.
