Philippe Braham, Yoav Hattab, Yohan Cohen and Francois-Michel Saada were murdered because they were Jewish, President Reuven Rivlin said at Har Hamenuchot cemetery on Tuesday as the victims of last week's shooting at a kosher market in Paris were laid to rest in Jerusalem."This was pure, venomous evil, which stirs the very worst of memories. This is sheer hatred of Jews; abhorrent, dark and premeditated, which seeks to strike, wherever there is Jewish life," Rivlin said.Rivlin called on European leaders to act to put a stop to such acts of anti-Semitic violence."It would be dangerous to deny that we are talking about anti-Semitism, whether old or new. Regardless of what may be the sick motives of terrorists, it is beholden upon the leaders of Europe to act, and commit to firm measures to return a sense of security and safety to the Jews of Europe; in Toulouse, in Paris, in Brussels, or in Burgas," he said."We cannot allow it to be the case, that in the year 2015, seventy years since the end of the Second World War, Jews are afraid to walk in the streets of Europe with skullcaps and tzitzit," he added.
