The U.S. believes they have killed a man who many analysts consider to be ISIS No. 2 in command, a U.S. official told CNN Friday.
The killed ISIS leader goes by several names, including Haji Imam and Abd al-Rahman Mustafa al-Qaduli, according to the official.
His death took place within the last two days in Syria, the official said, adding Qaduli was not killed by an airstrike, leaving open the possibility U.S. troops were involved.
The death is expected to be announced at a 10:45 a.m. Pentagon press briefing.
