Sources: Wanted al Qaeda terrorist killed in Pakistan

WASHINGTON (CNN) - Abu Laith al-Libi, a wanted al Qaeda terrorist, was killed in Pakistan by a CIA airstrike, three U.S. officials told CNN's Kelli Arena Thursday.

Al-Libi was described as a senior al Qaeda leader believed to have plotted and executed attacks against U.S. and coalition forces, including a February 2007 bombing at Bagram Air Base in Afghanistan during a visit by Vice President Dick Cheney. He was on a "most wanted" list of 12 accused terrorists issued in October by the Combined Joint Task Force-82 - an anti-terror unit in Afghanistan.

Earlier, a knowledgeable Western official and a military source confirmed al-Libi's death to CNN. The officials said al-Libi was killed by a missile from an airplane.
