A senior al Qaeda terrorist active in operational planning and training has been killed in Pakistan, a knowledgeable Western official and an unnamed military source said Thursday.
The official identified the terrorist as Abu Laith al-Libi, 41
The U.S. Government placed al-Libi on its most wanted list in 2006, behind bin Laden, al-Zawahiri and Taliban leader Mullah Omar
The official said al-Libi is "not far below the importance of the top two al Qaeda leaders" -- Osama bin Laden and Ayman al-Zawahiri.
al-Libi is of Libyan descent and has been in the Afghanistan/Pakistan border region
No word yet on the cause of death.
