Al-Qaeda Accuses Iran of 9/11 Conspiracy

You mean Iran and al-Qaeda aren't part of the same giant "Enemy"?

In an audio tape posted on the internet, Zawahiri insisted al-Qaeda had carried out the attacks on the US. He accused Iran, and its Hezbollah allies, of trying to discredit Osama Bin Laden's network.

Correspondents say the comments underline al-Qaeda's increasing public hostility towards Iran.
