The US delegation left the UN meeting after Ahmadinejad suggested that most people believe the 9/11 attacks were the work of people inside the US administration.
Iranian President Mahmoud Ahmadinejad told the United Nations on Thursday most people believe the U.S. government was responsible for the attacks of September 11, 2001, prompting the U.S. delegation to leave the room in protest.
In his speech to the General Assembly, Ahmadinejad said it was mostly U.S. government officials who believed the Islamist militant group al Qaeda was behind the suicide hijacking attacks that brought down New York's World Trade Center and hit the Pentagon.
Another theory, he said, was "that some segments within the U.S. 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 usually refers to Israel as the "Zionist regime."
"The majority of the American people as well as most nations and politicians around the world agree with this view," Ahmadinejad told the 192-nation assembly, calling on the United Nations to establish "an independent fact-finding group" to look into the events of September 11.
The U.S. and several European delegations left shortly after Ahmadinejad made the remarks.
Mark Kornblau, spokesman for the U.S. mission to the United Nations, reacted before Ahmadinejad finished speaking.
"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," he said.
Ahmadinejad raised a third theory about the attacks, saying: "It was carried out by a terrorist group, but that the American government supported and took advantage of the situation. Apparently this viewpoint has fewer proponents."
He said the main evidence for that theory was "a few passports found in the huge volume of rubble and a video of an individual whose place of domicile was unknown but it was announced that he had been involved in oil deals with some American officials."
"It was also covered up and said that due to the explosion and fire no trace of suicide attackers was found," he added.

I don't believe myself that the US planned and carried out the attacks, but i do feel that certain people within the intelligence services knew an attack was imminent and for whatever reason did very little to stop it.
