Thousands of people demonstrated in Rome, Paris and Madrid on Sunday in solidarity with Israel, as the Jewish state experiences weeks of escalating violence and daily terror attacks.<br />Demonstrators waved Israeli flags and sang the Israeli national anthem, "HaTikva," with one of the children performing Israeli singer David D'or's "Tishmor Al Haolam" .<br />The French rally, also organized by the Jewish community and the Union of French Jewish students , was attended by approximately 4,000 people, among them heads of the Jewish community and French politicians.<br />When we do not recognize the right of a country to defend itself against attacks with a knife, gun, and cars being rammed into people, it is the same as not recognizing its legitimacy," said Sacha Reingewirtz, the President of UEJF, standing at a podium adorned with a banner "French and Israelis united against terrorism."
