Sydney - An Australian previously jailed in Germany and Austria for declaring there were no mass killings of Jews in World War II was Wednesday sentenced to three months in jail by a court in Melbourne.

German-born former high school teacher Frederick Toben, 65, was found guilty of contempt for defying a court order requiring him to stop publishing anti-Semitic material on his website.

Toben was the subject of a civil action by Jeremy Jones, the former president of the Executive Council of Australian Jewry.

Last year Toben was held in London under a European Union arrest warrant because he was wanted by the District Court in Mannheim, Germany, to answer charges he published material on the internet of an anti-Semitic and/or revisionist nature. Denying the Holocaust is an offence in Germany with a maximum jail term of five years.

In 1999 Toben spent seven months in jail in Germany. He has also served an 11-month sentence in Austria for Holocaust denial.

In 2006 Toben was a speaker at a controversial two-day conference in Tehran organized by the Iranian government and attended by President Mahmoud Ahmadinejad. There, he described as "mere puffery" the assertion that the Nazis undertook mass killings of Jews.
