Aljazeera has aired an audiotape of Osama bin Laden's second-in-command, Ayman al-Zawahiri, calling on Pakistanis to overthrow President Pervez Musharraf. Al-Zawahiri said the Pakistani leader should be removed from power for "betraying" Islam, in a tape aired on Sunday. The top al-Qaida member accused Musharraf of making it possible for the United States "to kill thousands of innocents in Afghanistan". Al-Zawahiri also charged that the United States had withheld publication of part of a congressional report on the 11 September 2001 attacks because it proposed "prohibiting" Saudi Arabia from printing and distributing copies of the Qur'an, the Muslim holy text, for allegedly calling on worshippers to hate Christians and Jews. He urged Muslims around the world to fight what he described as a Christian-Zionist crusade "aimed at eradicating Islam and Muslims". "The crusade camp that is led by America ... is targeting Islam and Muslims, even if it claims that it is fighting terrorism. ... This campaign is seeking to abolish Islam as a doctrine and a law," the speaker said. He also criticized Israelis as arrogant, and called Sharon "the killer of Muslims and desecrator of the sanctity of al-Aqsa mosque." "His visit to India and the deals that he made with India ... such idiocy," the voice said. On 10 September Aljazeera also aired a videotape showing bin Laden and al-Zawahiri walking on a rocky mountainside, the first images of the two men in two years. The CIA said the men's voices on the accompanying audiotape were probably authentic. **PHOTO CAPTION*** Osama bin Laden. (AFP/File)
