A man thought to be al-Qaeda second-in-command Ayman al-Zawahiri calls for the overthrow of Pakistani President Pervez Musharraf in an audio cassette made public on this day. The man calls on Pakistanis to “unite and cooperate to topple this traitor and install a sincere leadership that would defend Islam and Muslims.” [Rashid, 2008, pp. 230, 436] There will be two apparently al-Qaeda-linked assassination attempts against Musharraf in December 2003 (see December 14 and 25, 2003).
