The Defense Department says an airstrike in Afghanistan last month killed Al Qaeda's top leader in the eastern part of the country.

Pentagon press secretary Peter Cook has issued a written statement saying a precision strike conducted by the U.S. military on Oct. 23 in Kunar, Afghanistan, killed Faruq al-Qatani.

Cook says al-Qatani was one of Al Qaeda's "senior plotters of attacks against the United States."

Cook says U.S. officials are still working to determine whether a second strike on the same date killed its target, Bilal al-Utabi, another Al Qaeda leader in Afghanistan.
