Today is Holocaust Day when the world remembers what was done across Europe in Nazi Germany's concentration camps.
On January 27, 1945, the Red Army liberated Auschwitz-Birkenau.
When the Soviet army arrived, most of the camp's prisoners had already been sent on a death march.
Approximately 7,000 prisoners were still alive when the camp was liberated.
All hate propaganda has the potential to erupt into something awful. At the entrance to the Holocaust museum in Berlin is this quote from Primo Levi. "It happened, therefore it can happen again: this is the core of what we have to say."
