ABC News' Tahman Bradley Reports:
Al Qaeda's second-in-command, Atiyah Abd al-Rahman, has been killed, the Obama administration said Saturday.
He was killed August 22 in Waziristan, Pakistan.
Believing al-Rahman was deeply involved in directing al Qaeda operations, an administration official said al-Rahman’s death is "a tremendous loss" for the organization, which the U.S. government said recently was near defeat.
Al-Rahman's power increased following the death of Osama bin Laden back in May. Al-Rahman was number two to Ayman al-Zawahiri, the leader of the terrorist organization.
Details about how al-Rahman died were not immediately released. The CIA launched a drone attack in Norak village of North Waziristan on August 22, striking a car. There is no confirmation that this was the attack that killed al-Rahman.
