Memorial photos of tourists with Ahmadinejad in Turkey

In September 2010, Ahmadinejad made a contentious assertion at the 65th session of the United Nations General Assembly by claiming that most people believe the United States government was behind the 9/11 attacks and later called for an inquiry, stating: “The fact-finding mission can shed light on who the perpetrators were, who is al-Qaeda … where does it exist? Who was it backed by and supported? All these should come to light.” The speech triggered many countries’ United Nations representatives to walk out, and US President Barack Obama described the claims as “inexcusable”, “offensive” and “hateful”. In 2010, Ahmadinejad reiterated the 9/11 conspiracy, and wrote:Establishing an independent and impartial committee of investigation, which would determine the roots and causes of the regrettable event of 9/11, is the demand of all the peoples of the region and the world. … Any opposition to this legal and human demand means that 9/11 was premeditated in order to achieve the goals of occupation and of confrontation with the nations.
