Eva Kor survived the Holocaust and went on to call for forgiveness of Nazi perpetrators, giving tours of the death camp at Auschwitz.

Axar.az reports citing foreign media.

She set up a small Holocaust museum in her adoptive home in the US and has died aged 85, during one of her annual trips to Poland.

Eva Mozes Kor was born in Romania and was deported with her Jewish family to Auschwitz in 1944.

Unlike the rest of her family, she and her twin sister Miriam survived.

But they were brutally abused by the notorious Josef Mengele, known as the Angel of Death, who was involved in selecting for death many of the 1.1 million Jews murdered in the gas chambers. The Nazis murdered six million Jews in World War Two.

As a doctor at Auschwitz from 1943, Mengele carried out torture on more than 1,000 twins and other Auschwitz prisoners as part of his warped idea of science.

"Three times a week we went to the blood lab. There we were injected with germs and chemicals and they took a lot of blood from us," she said in 2001. She developed a high fever and was given two weeks to live, but eventually recovered.

Mengele disappeared after the war and DNA tests later confirmed that he had drowned in Brazil in 1979.
