Doniecka, who goes to Auschwitz every year on the anniversary of its liberation, said that it was important for her to attend these events especially given she was in good health, unlike other survivors who were too ill or frail to travel.

One man's daring mission to infiltrate Auschwitz revealed its atrocities to the world – this is his story.

Tomorrow marks the 80th anniversary of the liberation of Auschwitz-Birkenau, the German-Nazi concentration and death camp where more than 1.1 million people were murdered between 1940 and 1945, about 85% of whom were Jews.

Holocaust survivors are sharing their personal stories as part of a new digital campaign launched by the Conference on Jewish Material Claims Against Germany (Claims Conference) ahead of the 80th anniversary of the liberation of Auschwitz.
