Italy's foreign minister Angelino Alfano on Monday condemned "anti-Semitism and all forms of discrimination", saying that historical memory was key to preventing a return to "the abyss".
"Even in contemporary Europe, indifference can lead to the abyss. It is memory that can save humanity," Alfano told a meeting in Rome.
"We cannot accept words that evoke racial supremacy," he said.
Alfano was opening the Conference on the Responsibility of States, Institutions and Individuals in the Fight against Anti-Semitism in the OSCE Area' taking place at the foreign ministry.
"Fanaticism can turn up anywhere and to stop it we need bold and immediate action," Alfano stated.
The Rome meeting was organised in cooperation with the Organisation for Security Cooperation in Europe and its Office for Democratic Institutions and Human Rights, and in conjunction with the Union of Italian Jewish Communities and the Foundation Jewish Contemporary Documentation Centre.
Italy is currently chairman of OSCE.
