— Italy’s Jewish community and a Holocaust survivors group expressed outrage Friday at the removal by vandals of three cobblestone plaques honoring Italian victims.German artist Gunter Demnig has laid thousands of such plaques around Europe in front of the homes of people later killed in the Holocaust. He calls them “Stolpersteine,” or stumbling blocks. Earlier this week, three such cobblestone plaques honoring the Spizzichino sisters were unveiled in Rome’s Jewish ghetto, where in 1943, during the occupation of the city by German troops, many residents were seized and sent to Nazi-run death camps. By Thursday the plaques were gone, but regular cobblestones remained. Italy’s Union of Jewish Communities has organized a protest for Saturday. “Holocaust survivors are “heart-sickened at this wanton act of vandalism, which is an offense against the memory and dignity owed the victims of the Nazis and the Fascists,” said a statement from Elan Steinberg, vice-president of the American Gathering of Holocaust Survivors and their Descendants.
