Delegates from the US and European countries walked out of the UN's General Assembly hall during Mahmoud Ahmadinejad's speech when the Iranian president claimed "most nations" believed the US government was behind the September 11 attacks.
In his speech to the UN, Ahmadinejad said there was a theory "that some segments within the US government orchestrated the attack to reverse the declining American economy, and its grips on the Middle East, in order to save the Zionist regime."
Ahmadinejad then said: "The majority of the American people as well as most nations and politicians around the world agree with this view," during which point the US delegation rose from their seats and left, along with a number of other countries' delegations.
In response the US delegation issued a statement:
"Rather than representing the aspirations and goodwill of the Iranian people, Mr Ahmadinejad has yet again chosen to spout vile conspiracy theories and anti-Semitic slurs that are as abhorrent and delusional as they are predictable."
