Their faces etched with fear, Jewish children and mothers carrying toddlers walk unknowingly to their horrendous fate.
These innocent victims were among around 1.1million people murdered by the Nazis at Auschwitz-Birkenau, near the town of Oswiecim, in what was then occupied Poland.
The victims at Auschwitz were among 6million Jews who were murdered by Adolf Hitler's forces between 1941 and 1945. Their lives are commemorated today on Holocaust Memorial Day.
The rare photos taken at Auschwitz by Hitler's SS guards show not only the arrival of Hungarian Jews at the camp - on rail tracks built specifically in 1944 for the extermination operation - but the long queues as they waited to walk to gas chambers.
