Iran's supreme leader Ayatollah Ali Khamenei expressed doubts over the validity of the Holocaust in remarks on Friday, AFP reported.
In a live broadcast from the city of Mashhad, Khomeini said that in Europe, "no one dares to speak of the Holocaust, the crux of which is not clear if it is true, or if it were, how it was."
Khamenei has in the past made controversial statements regarding the Holocaust, calling the systematic killing of six million Jews by Nazis a "myth."
The comments come just one day after Iran and Western powers ended two-day talks in Vienna over Tehran's nuclear program.
