It doesn’t do any good for your heart, for your mind, for anything,” said Holocaust survivor Jona Laks, 94, about her return to Nazi Germany’s Auschwitz-Birkenau concentration camp.

OSWIECIM, Poland (AP) — The 80th anniversary of the liberation of Auschwitz by Soviet troops is being marked on Monday at the site of the former death camp, a ceremony that is widely being treated as the last major observance that any notable number of survivors will be able to attend.

Survivors of the Nazi's notorious Auschwitz death camp are taking center stage at the memorial service to mark 80 years since its liberation by Soviet troops.

At Auschwitz, the Germans left behind barracks and watchtowers, the remains of gas chambers and the hair and personal belongings of people killed there. The “Arbeit macht frei” (work will set you free) gate is recognized the world over.
