Is al-Qaida now targeting Iran? As is well known, al-Qaida is a radical Sunni organization while the Islamic Republic of Iran is a revolutionary Shiite regime. Sunnis and Shiites have been fighting each other in Iraq, and animosity between the two communities has been growing in Lebanon. The recent denunciation of Iran by bin Laden deputy, Ayman al-Zawahiri, raises the possibility of direct confrontation between al-Qaida and Tehran inside Iran.
