"We survivors do not want our past to be our children's future," Roman Kent, born in 1929, told a memorial gathering at the death camp's site in Poland. Some 300 Auschwitz survivors returned for the ceremony under a giant tent. Some 1.1 million people, mostly Jews, were killed there between 1940 and 1945, when Soviet troops liberated it. It is expected to be the last major anniversary event survivors are able to attend in considerable numbers. Ronald S Lauder, president of the World Jewish Congress, told the commemoration: "Jews are targeted in Europe once again because they are Jews... "Once again young Jewish boys are afraid to wear yarmulkes [skullcaps] on the streets of Paris, Budapest, London and even Berlin." In the Czech capital Prague, speakers of parliament from across the EU gathered with the European Jewish Congress to issue a declaration condemning anti-Semitism and hate crimes.
