Iran's Ahmadinejad: Sept. 11 attacks a 'big lie'

Iran's hardline President Mahmoud Ahmadinejad has again questioned the official version of the Sept. 11 attacks in the US, calling it a "big lie" used as an excuse to invade Afghanistan and Iraq.
Iranian state television quoted Ahmadinejad on Saturday as saying the 2001 attacks were an "intelligence scenario and act."
