According to the president, al-Zawahiri moved to the centre of Kabul after being detected earlier this year by the intelligence community.
Al-Zawahiri, who was born in Cairo in 1951, studied medicine before establishing the Egyptian Islamic Jihad.
Before joining forces with al-Qaeda in 1998 and 1999, his organisation had attempted to overthrow the Egyptian government through violent means.
As Osama bin Laden's al-Qaeda deputy, al-Zawahiri helped coordinate the September 11, 2001, terror attacks in the United States, which killed nearly 3,000 people.
