Even al-Qaeda is sick of hearing Iranian President Mahmoud Ahmadinejad’s conspiracy theories.

In an address before the U.N. General Assembly last week, Ahmadinejad reiterated his belief that the U.S. government was somehow behind the attacks.

The magazine appears to have criticized the Iranian leader because it didn’t want anyone else taking credit for the attacks, writing: “Iran and the Shi’a in general do not want to give al-Qaeda credit for the greatest and biggest operation ever committed against America.”

The issue was entitled “The Greatest Special Operation of All Time,” and its cover image shows a silhouette of the World Trade Center made up of dollar signs. (See below.)

Also included was a photo preview of the next edition of the magazine, showing what appears to be Americans in long robes in front of Grand Central Station with the caption: “Targeting the populations of countries that are at war with the Muslims.”

An FBI official told Fox News that “Grand Central Station is not a new threat target,” and that the Joint Terrorism Task Force “continues to work diligently with our partners throughout the city to mitigate every threat and keep every target safe.”

The issue was the seventh for the glossy English-language magazine, which was created by New Mexico-born cleric Anwar al-Aulaqi in July 2010 to spread the message of al-Qaeda and help inspire homegrown terrorism. Aulaqi is believed to be in hiding in Yemen.
