Iran's supreme leader on Wednesday once again repeated provocative assertions about the Holocaust, defying the world on a day that it paused to remember the victims of the Nazi genocide in Europe.Ayatollah Ali Khamenei released a video in which he said America “assists the fake Zionist regime” and that when “they say in their slogans that they are opposed to terrorism and ISIS they are lying,” according to a translation by the Middle East Media Research Institute.Of the Holocaust, Khamenei remarked: “It is not clear whether the core of this matter is a reality or not. Even if it is a reality, it is not clear how it happened...This is the ignorance that exists in today’s world. We should be awake. [Muslims] should know that we can stand up against the ignorance.” "Who assists the fake Zionist regime," Khamenei says in the video. "Who supports them, who clears the road for them, who stands behind them.""It is Western powers headed by America that are doing so. This is while they say in their slogans that they are opposed to terrorism and ISIS.""They are lying, they say things that aren't true. This is ignorance (Statue of Liberty)."Khamenei then begins to cast aspersions on the veracity of the Holocaust, saying: "No one in European countries dares to speak about the Holocaust (Auschwitz).""While it is not clear whether the core of this matter is a reality or not, even if it is a reality, it is not clear how it happened," the supreme leader is heard saying.Speaking about the Holocaust and expressing doubts about it is considered to be a great sin.""If someone does this they stop, arrest, imprison, and sue him," the cleric said. "This is while they claim to be supporters of freedom. This is the ignorance that exists in today's world. We should be awake. [Muslims] should know that we can stand up against the ignorance."
