Britain's Prime Minister Tony Blair joined Holocaust survivors Thursday to mark the 61st anniversary of the liberation of the former Nazi concentration Auschwitz-Birkenau.
The prime minister and his wife, Cherie, were in Cardiff, Wales, to mark Britain's sixth annual Holocaust Memorial Day. They were joined by men and women who helped to hide and rescue those facing persecution at the hands of the Nazis.
Survivors and witnesses of other cases of genocide - including the slaughter of tens of thousands in Rwanda - were also among those who attended.
Blair told the audience that the Holocaust was an incomparable evil. "Nothing compares to the Holocaust, not in the intensity of its evil, not in the ghastly scope of its inhuman ambition and in the fact that for a time it threatened to engulf our entire world," he said.
