ITALY-US-IRAQ-IS-RELIGION-LAUDER

US Ronald S. Lauder, president of the World Jewish Congress, shows a piece of paper with the Nuun or Nun symbol which IS (Islamic State) allegedly daubed to indicate the homes of Christians in Irag during a press conference at the Stampa Estera " Foreign Press Association " in central Rome, on September 18, 2014. The symbol has been taken up by IS as it stands for the word "Nasara" or Nazarene. Copying the practice of the Ottoman Caliphate, Christians whose homes had been marked with the Nuun were given an ultimatum to convert, pay a steep tax, or flee. Western Christians have taken up the symbol to show solidarity with their Iraqi coreligionists. AFP PHOTO / ANDREAS SOLARO (Photo credit should read ANDREAS SOLARO/AFP via Getty Images)
