Osama bin Laden's chief deputy in an audiotape Tuesday accused Shiite Iran of trying to discredit the Sunni al-Qaida terror network by spreading the conspiracy theory that Israel was behind the Sept. 11 attacks.
The comments reflected al-Qaida's No. 2 leader Ayman al-Zawahri's increasing criticism of Iran. Al-Zawahri has accused Iran in recent messages of seeking to extend its power in the Middle East, particularly in Iraq and through its Hezbollah allies in Lebanon.
Did Ahmadinejad say that Israel was behind 9/11?
"The purpose of this lie is clear — (to suggest) that there are no heroes among the Sunnis who can hurt America as no else did in history. Iranian media snapped up this lie and repeated it," he said.
"Iran's aim here is also clear — to cover up its involvement with America in invading the homes of Muslims in Afghanistan and Iraq," he said.
Iran cooperated with the United States in the 2001 U.S. assault on Afghanistan that toppled al-Qaida's allies, the Taliban.
Al-Zawahri spoke on a wide range of issues, even global warming, which he said reflected "how criminal, brutal and greedy the Western Crusader world is, with America at the top."
He predicted that global warming would "make the world more sympathetic to and understanding of the Muslims' jihad against the aggressor America."
