The publication of the diary of the first head of the Soviet KGB, may finally shed some light on one of the enduring mysteries from World War Two; what happened to Swedish diplomat Raoul Wallenberg?

Wallenberg saved tens of thousands of Hungarian Jews during the Holocaust then  disappeared while in Soviet custody in 1947.

Now, for the first time, the diary of KGB head Ivan Serov indicates Wallenberg was put to death on the orders of former Soviet dictator Joseph Stalin. All that has been previously conformed by the Soviets is that Wallenberg died in prison in 1947.

Wallenberg, was a special envoy sent to Budapest in 1944 with the goal of saving the 230,000 remaining Jews from the gas chambers by issuing special Swedish “protective passports”.  He was arrested by the Soviets in 1945 and never heard from again.

The Yad Vashem Holocaust Remembrance Center in Jerusalem declared Wallenberg “Righteous Among the Nations” in 1963.
