(CNN)The Pentagon said Friday that it had killed ISIS' number two leader, Abd al-Rahman Mustafa al-Qaduli.
Analysts believe al-Qaduli would have been expected to take control of the day-to-day running of ISIS if its leader, Abu Bakr al-Baghdadi, was killed or incapacitated.
Defense Secretary Ash Carter announced the death at a press conference.
"We are systematically eliminating ISIL's cabinet," Carter said, adding it was "the second senior ISIL leader we've successfully targeted this month."
