Hamid-Reza Assefi also invited British Prime Minister Tony Blair to take part in what Tehran calls "scientific seminar" on the Holocaust to clarify "the real dimensions of the Holocaust."
Blair has lashed out at the planned meeting as "shocking, ridiculous, stupid," and said President Mahmud Ahmadinejad should come and see the evidence of the Holocaust himself in Europe.
Ahmadinejad sparked international outrage last year when he called for the eradication of Israel, branded the Holocaust a "myth" and called for the relocation of Israel.
The Holocaust applies to the extermination of some 6 million Jews in Nazi-occupied Europe during World War II.
