Al-Jazeera airs al-Qaida tape urging war on Western world
The broadcast followed US warnings of imminent al-Qaida attacks in the Unites States, the Middle East and Africa.
The tape by Ayman al-Zawahri appeared to have been made in the early days of the US-led war on Iraq and made no mention of the recent wave of suicide bombings which killed at least 75 people in Morocco and Saudi Arabia, bin Laden's birthplace.
