NBC's Jim Miklaszewski reported:
Three leaders of ISIS have been killed by American airstrikes in Iraq in the past month and a half, U.S. defense officials said Thursday.
They were identified as Haji Mutazz, a deputy to the ISIS leader; Abd al-Basit, the top military commander; and Radwin Talib, who is in control of ISIS in Iraq.
One official called the deaths of Mutazz and al-Basit in particular a "serious blow to ISIS command and control." The official said that the setback may be temporary because ISIS has plenty of willing replacements.
CNN reports that the ISIS leaders were very high-ups. One of them was the Al-Baghdadi's deputy in Iraq. Watch the video.
