Al-Qaeda leader Ayman al-Zawahiri, who has been killed in a US drone attack in Afghanistan, was the group’s key ideologue and strategist, masterminding its global network and planning attacks on the United States.
The 71-year-old Egyptian eye doctor had central roles in the attacks on the US embassies in Kenya and Tanzania in 1998, and the 9/11 attacks on Washington, DC and New York City, where nearly 3,000 people were killed.
