Several anti-Semitic graffiti, including one saying "Holocaust is a Jewish Lie," appeared Thursday on the walls of a World War II Nazi death camp in central Serbia. Jasna Ciric, the head of the Jewish community in Nis, said the graffiti was apparently timed to coincide with the 64th anniversary of the massacre of some 1,100 Jews, Serbs and Gypsies in the camp. "It's unbelievable that such messages are still alive in the 21st century," Ciric said, adding that about 12,000 people were killed by Nazis in the Bubanj concentration camp during World War II. The other paint-written graffiti included: "Serbia for Serbs" and the infamous "Arbeit Macht Frei" (work liberates) slogan of the notorious Auschwitz death camp. Serbia has seen a surge of anti-Semitism in recent years, fueled by nationalists who claim that all the republic's problems stem from the powerful Jews who allegedly support anti-Serb policies in the United States and elsewhere in the world.
