A Yad Vashem spokeswoman said there is no proof the Nazis made soap from human bodies during the Holocaust.
The sources said similar claims have been made in the past regarding soap made from Jewish bodies, including soap found last year in the Nahariya cemetery. In that case the soap was determined not to have been made from human remains.
In 1990 samples from several soaps claimed to have been made from Jews were sent for DNA testing at Tel Aviv University. Likewise, those tests determined the soaps did not contain human fats.
