Stockholm: Researchers investigating the fate of World War II hero Raoul Wallenberg say a newly found Swedish document shows the Soviet secret police intervened in the early 1990s to stop an international commission probing his disappearance.
The 1991, memorandum from the Swedish Embassy in Moscow cites the former head of the Soviet "Special Archive" as saying the KGB instructed him to stop a search for documents by researchers working for the commission.
The memo was made available to a news agency by Susanne Berger, a German researcher based in the United States.
The Swedish diplomat, who would have turned 100 this year, is credited with rescuing tens of thousands of Hungarian Jews from the Nazis. He disappeared after being arrested by the Soviet Red Army in 1945.
