Two days before his official trip to Afghanistan, Iranian President Mahmoud Ahmadinejad called the terrorist attacks of September 11, 2001, a "big lie" intended to pave the way for the invasion of a war-torn nation, according to Iranian state media.

Ahmadinejad, known for his harsh rhetoric toward the West and Israel, said the attack on U.S. soil was a "scenario and a sophisticated intelligence measure," Iran's state-run Press TV reported Saturday.

The assault was a "big lie intended to serve as a pretext for fighting terrorism and setting the grounds for sending troops to Afghanistan," Press TV reported Ahmadinejad as saying.
