Nazilerin Karanlık Dünyası

A visitor is seen behind the lettering "Arbeit macht frei" (work makes you free) at the entrance of the memorial site of the former Nazi concentration camp Auschwitz-Birkenau in Oswiecim, Poland, on January 25, 2015. Seventy years after it was liberated, 300 Auschwitz survivors -- most now in their nineties -- will on January 27, 2015 return to the former Nazi death camp, the site of the largest single number of murders committed during World War II.
