A Holocaust survivor who lived through four concentration camps will return to Auschwitz to mark 80 years since liberation of the notorious Nazi camp.

Furst, now 92, is one of a dwindling number of Holocaust survivors able to share first-person accounts of the horrors they endured, as the world marks the 80th anniversary of the liberation of the Nazis' most notorious death camp. Furst is returning to Auschwitz for the annual occasion, his fourth trip to the camp.

Commemorations are being held Monday to mark the 80th anniversary of the liberation of the Auschwitz death camp by Soviet troops

But it will be the survivors - most in their late 80s and 90s - not the dignitaries, whose voices will be heard during the commemorations at the camp, where 1.1 people were murdered, most of them Jews.
