VIENNA—An Austrian court has found a man who claimed the mass killings of Jews in gas chambers under Adolf Hitler was a story made up by Jews guilty of violating the country’s anti-Nazi laws and sentenced him to a suspended 12-month prison term.

Additionally, the man has been convicted of the crime of incitement for calling Muslims vermin. The court in the western city of Feldkirch ordered him Monday to pay a fine of 1,440 euros ($2,109).

Both statements were made on Facebook. In claiming that the mass gassings were fiction, the man said Jews made up the story to make Hitler look bad should he have won the war.

The 34-year old acknowledged the postings were his. He is not being identified in keeping with Austrian privacy laws.
