The accusation was based on the fact that Hanningm was “aware that in Auschwitz innocent people were murdered every day in gas chambers.” The World Jewish Congress welcomed the verdict, “He was part of a merciless killing machine. Without the active participation of people like him, Auschwitz would not have been possible,” Congress President Ronald S. Lauder said. Hanning participated in the so-called “Hungary Operation” of 1944, when some 425,000 Hungarian Jews were deported to Auschwitz, where the majority of them were gassed to death on arrival. “No one in my family knew that I worked at Auschwitz. I simply couldn’t talk about it. I was ashamed,” Hanning told the court. He expressed regrets.
