Rome, October 31 - Israeli President Reuven Rivlin on Monday described a UNESCO resolution on Jerusalem holy sites cited only by their Arab names as a crime after meeting Italian President Sergio Mattarella in the city. "The recent UNESCO resolution is a historic crime and I am grateful to Italy for its defence of the truth," Rivlin said. Last week Italian Foreign Minister Paolo Gentiloni said Italy will move from abstaining to voting against the UNESCO resolution if it is not changed next time. He said the resolution, which has been voted twice a year since 2010, since 2014 "has contained terms that deny the Jewish roots of the Temple Mount". Gentiloni said UNESCO shouldn't be "a sounding board for political tensions," and should keep its focus on cultural heritage. Premier Matteo Renzi described the recent UNESCO resolution calling on Israel to stop excavating near holy sites in East Jerusalem was "unreal". "It's incomprehensible, unacceptable and wrong," Renzi told private RTL 102.5 FM radio in an interview.
