Iranian President Mahmoud Ahmadinejad said Monday he was proud his denial of the Holocaust had enraged the West, as the controversial leader geared up for a United Nations trip to stress what he said would be a message of "peace and friendship."

Ahmadinejad's latest comment about the killing of millions of Jews during World War II comes as Iran is locked in a bitter dispute with the U.S. and other Western nations over its nuclear program. Even as that fight continues, his remarks were sure to earn the Iranian president an even more frigid reception when he heads to New York on Tuesday to attend the U.N. General Assembly.

Ahmadinejad has repeatedly raised questions about the Holocaust. He has said it has been used as a pretext for Israel's formation, and that Israel and Jewish groups are actively muzzling any attempt to link shame over the Nazi atrocities with the what many in the Muslim Middle East believe is the West's bias for the Jewish state at their expense.
