An Austrian news agency reported on Friday that an imprisoned right-wing writer will go on trial this month on new charges related to his alleged defense and promotion of the Nazi era. According to the report, the trial for 68-year-old Gerd Honsik will begin April 20 in Vienna. Officials could not be reached for comment late Friday. The agency said that Honsik faces up to 20 years in prison if convicted of denying the Holocaust or promoting Nazi propaganda. Hosnik is currently serving an 18-month sentence on a 1992 conviction for writing the book "Hitler Innocent?" in which he attempts to justify some Nazi-era crimes. He began serving the sentence in December 2007, as he fled following his conviction and was extradited from Spain only in October 2007.
