Monday’s ceremony marking the 80th anniversary of the liberation of Auschwitz is more than just the moment to remember some 6 million Jews who died in the Holocaust. It is a reminder that the number of survivors is dwindling rapidly, leaving fewer and fewer people to bear witness to the horrors of the Nazi genocide at a time when Holocaust denial and antisemitism are on the rise. That's why survivor Manfred Goldberg is determined to keep telling his story, as long as he can. (AP Video by Kwiyeon Ha)
