When pressed about the treatment of homosexuals in his country, Iranian President Mahmoud Ahmadinejad was translated as saying his country did not have homosexuals and questioned where anyone had heard there were gays in Iran.

"In Iran, we don't have this phenomenon," he said through an interpreter, "I don't know who's told you that we have it."

This drew laughs and boos from the audience at Columbia University, where he was speaking Monday afternoon in a controversial question-and-answer session.

Ahmadinejad gave a short address and then answered questions for about an hour. He spoke after sitting through a verbal attack from Columbia President Lee Bollinger.

Bollinger attacked his record on human rights and statements questioning the Holocaust.
