(CNN) — The Pentagon said Friday that it had killed ISIS’ No. 2 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, also called ISIL, if its leader, Abu Bakr al-Baghdadi, was killed or incapacitated.
Defense Secretary Ash Carter announced the death at a press conference Friday morning.
“We are systematically eliminating ISIL’s cabinet,” Carter said, adding it was “the second senior ISIL leader we’ve successfully targeted this month.”
A U.S. official told CNN that al-Qaduli was involved in overseeing the terrorist group’s finances.
This is not the first time al-Qaduli has been reported killed. In July, the Iraqi Defense Ministry claimed a coalition air strike had killed him in Tal Afar in northern Iraq.
At the time U.S. Central Command, which oversees military operations in the region, debunked the claim, saying it had “no information to corroborate” that ISIS’ second-in-command had been killed.
The U.S. Treasury labeled al-Qaduli “a specially designated global terrorist” in 2014. He also goes by 12 aliases including, Hajji Iman, according to the Treasury.
The U.S. State Department had offered a $7 million reward for information on al-Qaduli — the highest for any ISIS leader apart from al-Baghdadi, who is valued at $10 million.
That sizable bounty makes al-Qaduli the sixth-most-wanted terrorist in the world, ranking only behind the likes of the heads of al Qaeda, ISIS and the Taliban’s Haqqani network.
Al-Qaduli was born in Mosul, Iraq’s second-largest city, in either 1957 or 1959.
He initially joined Al-Qaeda in Iraq — the group that would evolve into ISIS — in 2004, serving as a top deputy to then-leader Abu Musab al-Zarqawi and emir of the group’s Mosul branch.
He was captured and jailed by Iraqi authorities but was released in 2012, at which point he rejoined the terror group in Syria, according to the U.S. State Department.
Al-Qaduli is also believed to go by the name Abu Alaa al-Afri, but CNN cannot independently confirm that that is the same person.
Al-Afri is reputed to have been a physics teacher and a favorite of al-Qaeda leader Osama bin Laden.
He is an ethnic Turkmen, which analysts say was a barrier that could have prevented him from succeeding ISIS leader Abu Bakr al-Baghdadi.
