Rome, September 5 - Special investigators were called in Thursday after an anti-Semitic site that included Holocaust denials appeared on Facebook. "Ebrey Today", which reportedly appeared about two weeks ago, gained hundreds of "likes" for jokes about Jews, and revisionist history that denies such atrocities as the Holocaust of World War Two. Followers could also "like" convicted neo-Nazi extremists. A similar page that appeared earlier this year was shut down. The anti-terrorism unit, Digos, of Rome is investigating.
