On May 2, 2011, Navy SEALs shot and killed al- Qaida leader and Sept. 11 mastermind Osama bin Laden in his home in Abbottabad, Pakistan. It was a raid made especially daring by the fact that there was only a 50-50 chance the terrorist leader was there. After his death, these are five of the top al-Qaida leaders who pose a clear and continuing threat of an attack within the U.S., according to U.S. intelligence and counterterrorist officials:

Ayman al-Zawahri, Egyptian cleric Ayman al-Zawahri took over the organization, after Osama bin Laden’s killing.

Abu Yahia al-Libi, Libyan militant, now the group’s de facto No. 2 moving up a notch in al-Qaida hierarchy after the bin Laden raid.

Mullah Mohammed Omar, leader of the Taliban. Afghan Mullah Omar has sheltered al-Qaida during the Taliban rule and since.

Nasser al-Wahishi, once bin Laden’s aide-de-camp, commands Yemeni affiliate al-Qaida in the Arabian Peninsula, or AQAP, the group U.S. counterterrorist officials warn is most capable of launching an attack on U.S. soil.

Ibrahim Hassan al-Asiri, chief bombmaker for al-Qaida in the Arabian Peninsula, responsible for building the underwear bomb used to try to bring down a Detroit-bound jetliner on Christmas 2009 and the printer-cartridge bombs intercepted in U.S.-bound cargo planes a year later.
