TEHRAN, Iran – Iran's hard-line President Mahmoud Ahmadinejad on Saturday called the official version of the Sept. 11 attacks a "big lie" used by the U.S. as an excuse for the war on terror, state media reported. "September 11 was a big lie and a pretext for the war on terror and a prelude to invading Afghanistan," Ahmadinejad was quoted as saying by state TV. He called the attacks a "complicated intelligence scenario and act."
