Iranian President Mahmoud Ahmadinejad has said he believes - as an engineer - the World Trade Center towers could not have been brought down by aircraft. ... But he stopped short of saying the US staged the disaster 10 years ago. He had been widely condemned for using his UN address to brand the US killing of Osama Bin Laden a 9/11 cover-up. ... [H]e was fiercely critical of the operation against Osama Bin Laden, when, he said, the US "killed the main perpetrator [of 9/11] and threw his body into the sea". "Would it not have been reasonable to bring to justice and openly bring to trial the main perpetrator of the incident in order to identify the elements behind the safe space provided for the invading aircraft to attack the twin World Trade Center towers?" he had told the assembly. The Iranian president has previously called the 9/11 attack a "suspect event" and a "big fabrication" used to justify the US war on terrorism.
