US President Barack Obama on Friday said Iranian President Mahmoud Ahmadinejad, who again this week called the Holocaust a "great deception," should visit the site of the Buchenwald concentration camp.
In an interview in Germany with NBC News shortly before making his own trip to Buchenwald to pay homage to victims of World War Two and the Holocaust, Obama was asked what he thought the Iranian leader could learn from his visit to the site.
"He should make his own visit," Obama said. "I have no patience for people who would deny history. And the history of the Holocaust is not something speculative."
This week Ahmadinejad called the Holocaust a "great deception" during a speech containing his latest verbal assault on Israel, which the Islamic Republic does not recognize.
Obama noted that his great uncle helped liberate a camp of Buchenwald during World War Two. The concentration camp in eastern Germany was created by the Nazis and an estimated 56,000 people, mostly Jews, were killed there.
