[JURIST] Austrian prosecutors filed charges Tuesday against British historian David Irving [BBC profile], who was arrested last week [JURIST report] for violating an Austrian law making it illegal to deny the Holocaust. Prosecutor Otto Schneider said, "A charge was filed in relation to two speeches in 1989 in which he denied the existence of gas chambers." Irving has previously argued that Hitler was not aware of the execution of six million Jews and that the scale of the extermination of the Jews during World War II has been exaggerated. A hearing to determine whether Irving should remain in custody for an additional four weeks will be held on Friday. BBC News has more.
