Holocaust survivors joined Jewish and military leaders Friday at a solemn ceremony to mark the 60th anniversary of the liberation of the Bergen-Belsen concentration camp.
As many as 70,000 people died at the Nazi camp in northern Germany, which was liberated by British troops on April 15, 1945.
Jonathan Sacks, Britain's chief rabbi, and army chief of staff Gen. Sir Mike Jackson addressed the ceremony at the Holocaust Memorial in London's Hyde Park.
Rudi Oppenheimer, 73, spoke of his experience as a child in the camp.
"I was incarcerated only because I am a Jew, and the world stood by and let this happen," he said. "I am the little boy who stood at the barbed wire fence in Belsen and saw. I am the witness, and you people here in the audience have heard me."
Teenage diarist Anne Frank was among the camp's victims. She died of typhus a few weeks before the camp was liberated, one of 1.5 million Jewish children killed during the Holocaust.
