Anti-Semitism

FILE - In this file photo from May 2, 2013, a visitor looks at a poster of the former Nazi concentration camp of Mauthausen during a press preview in a new memorial room at the former camp in Mauthausen, Austria. The concentration camp was liberated by U.S. troops on May 5, 1945. A new survey released on Thursday, May 2, 2019, has found that many Austrians lack basic knowledge of the Nazi genocide, even though the notorious Mauthausen concentration camp was just outside of the city of Linz, and some of the key perpetrators of the Holocaust were Austrian.
