Iran’s supreme leader is once again making Holocaust denials.

In a Twitter post March 21, Ayatollah Ali Khamenei wrote: “#Holocaust is an event whose reality is uncertain and if it has happened, it’s uncertain how it has happened.”


The message was uploaded to the account, which is widely regarded as Khamenei’s creditable handle.

Jewish groups were quick to condemn the comments, with the Anti-Defamation League calling the remarks bigoted and hypocritical.

“Once again, the injection of Holocaust denial by an Iranian leader shows the world how such deep-seated hatred exists at the helm in Iran,” Abraham Foxman, the Anti-Defamation League’s national director, said.

“We have seen the Ayatollah spew his vehement animosity toward Jews before on other national occasions in Iran, and these statements once again show the bigotry and hypocrisy of this regime.”

The Conference of Presidents of Major American Jewish Organizations and the World Jewish Congress also issued statements this week criticizing the tweet, which is in line with other social media messages Khamenei has posted in the past.
