Ahmadinejad was quoted by the Iranian News Agency (IRNA) as saying that the angering of "professional man-slayers is a source of pride for us and will not stand in our way", apparently in reference to Israel and the West.
"The more these imperialists, enemies of humanity and those whose hearts have no love for the human kind run wild, screaming and throwing accusations, we know our path is correct," said Ahmadinejad.

During his speech Friday in Tehran University, the president once again questioned the existence of the Holocaust: "If the Holocaust was planned by the west, why won't they let anyone investigate it? They have turned the holocaust into a black box and won't let anyone open and examine it…if this event is so important why don't they let us expose the truth to the whole world?"
Ahmadinejad continued to attack Israel, saying that "Zionists are the biggest criminals in history, and resisting them is a national duty, a religious commandment and a human obligation. The Zionist regime is a tree with rotten roots."
"It is obvious this deceptive regime was founded to fulfill colonialist aspirations, and that there is no logic behind its establishment," added the president, to which the crowd replied: "Death to Israel."
Ahmadinejad's words received condemnations from around the world; Britain announced that the Iranian President's Holocaust denial is repulsive and is a sign of ignorance, adding that the national community must stand against him united.
The German foreign minister said that Ahmadinejad brings shame to his country, while the White House said his words only increase Iran's isolation from the rest of the world.
Russia, Iran's ally, also condemned Ahmadinejad's speech, saying that "his words oppose the truth and are completely unacceptable. The attempt to deny history, especially in the year that marks 70 years to the beginning of the war, desecrates the memory of the victims and all who fought against fascism."
