(ANSA-AFP) - BRUSSELS, JAN 26 - Israel's President Isaac Herzog on Wednesday urged Europe to fight anti-Semitism "at all costs", in the face of a worrying increase in hatred being spread notably online. "The picture is very deeply troubling, anti- Semitic discourse festers not only within dark regimes but within the heartland of the free democratic West," Herzog said in a speech to the European Parliament to mark Holocaust Remembrance Day. "Jew-hatred still exists. Anti-Semitism still exists. Holocaust denial still exists." Herzog pointed to reports showing rising incidents of anti-Semitism, especially online where it was "spreading at a record pace at the click of a button". "I call on you, elected officials of Europe: do not stand by, you must read the warning signs, detect the symptoms of the pandemic of anti-Semitism and fight it at all costs," he said. (ANSA-AFP).
