Ayman al-Zawahiri succeeded Osama bin Laden as al-Qaeda leader after years as its main organizer and strategist, but his lack of charisma and competition from rival militants ISIS hobbled his ability to inspire sizeable attacks on the West.
Zawahiri, 71, was killed in a US drone strike, US President Joe Biden said on live television on Monday evening. US officials said the attack took place on Sunday in the Afghan capital Kabul.
