Anne Frank's diary will be read aloud at all soccer matches in Italy this week, the Italian soccer federation announced Tuesday after shocking displays of anti-Semitism by fans of the Rome club Lazio.

Lazio supporters on Sunday littered the Stadio Olimpico in Rome with images of Anne Frank – the young diarist who died in the Holocaust – wearing a jersey of city rival Roma. The ultra right-wing fans of Lazio associate their Roma counterparts with being left-wing and Jewish, and had hoped to incite Roma fans, since the teams share the same stadium.

Stadium cleaners found the anti-Semitic stickers on Monday and Italian police have opened a criminal inquiry into the case.
