SWEDEN, October 11 - Today, few survivors remain to bear witness to the horrors of the Holocaust. The opening Plenary Session reflects on the consequences of the diminishing number of survivors and witnesses of the Holocaust, the Roma genocide and the persecution that different groups were exposed to during the Holocaust. The international community has an obligation to ensure that the Holocaust is remembered and that future generations understand the causes of and the process leading up to the Holocaust, and to reflect on its consequences to prevent this from ever happening again
