April 18, 2008: Al-Zawahiri Said to Mark Fifth Anniversary of Iraq Invasion with New Tape

A man thought to be al-Qaeda’s second-in-command Ayman al-Zawahiri releases a 16-minute audio tape around five years after the US and others invaded Iraq. The man calls on Islamist fighters to turn Iraq into a “fortress of Islam,” and says the establishment of a greater Islamic state is “the most important” duty of every Muslim. The tape contains references to recent events—testimony by US General David Petraeus to Congress and a strike by textile workers in Egypt. The man is also critical of Iran for siding with the US against Sunni Arabs in Iraq. [Guardian, 4/18/2008]
