German media recently reported that the names of eight Nazi criminals were passed to the German federal authorities three years ago, but the government refuses to try them.
All eight of these criminals were members of Germany's Einsatzgruppen, or mobile death squads, and participated in the Babi Yar massacre.
Babi Yar is a ravine in the Ukrainian capital city of Kiev where the Nazis conducted massacres, the most notorious of which took place on September 29-30, 1941, when 33,771 Jews were murdered.
Israeli Nazi hunter Dr. Efraim Zuroff researched the names of former Einsatzgruppen members himself and then found those born in or after 1920. There were 76 men and four women.
Former German Foreign Minister Joschka Fischer, who is a member of the organization which runs the Babi Yar memorial site, said he does not understand why the German government does not prosecute the former Nazis.
"It is the government's obligation to act in cases of mass murder," he said.
On September 12, a German court officially dropped its case against former Auschwitz medic Hubert Zafke, 96, because he has dementia.
