Italian authorities are investigating a YouTube channel that posted songs setting anti-Semitic lyrics to Italian hit tunes. The songs, whose lyrics urge death to Jews and make fun of the Holocaust, appeared earlier this month on a YouTube channel that apparently originates in Italy. They have already been taken off-line by the unknown persons who posted them. The channel profile for "99fosse" opened April 19, 2008 and remains active, but no videos are posted. It identifies the owner as 24 and Italian. Political leaders, including Rome's mayor, condemned the incident. "There is a cancer on the Net that allows diffusion of pedophile pornography and anti-Semitic material and allows scam artists to operate on-line," said Rome's Jewish community president, Riccardo Pacifici.
