International Holocaust Remembrance Day-70th anniversary of the liberation of Auschwitz-Berkenau.
The German Nazis opened the Auschwitz-Berkenau, Poland, concentration camp (15 square miles) in 1940. They killed at least 1.1 million people, mostly Jews, due to xenophobia, antisemitism and hatred.
On 27 January,1945, the Soviet army liberated the camp.
Today, about 300 former prisoners take part in the events.
