Since mid-November, the U.S. military has killed three senior ISIS leaders, the Pentagon told The Wall Street Journal on Thursday.
In early December, military airstrikes in Iraq killed Abd al Basit, the head of the terrorist group's Iraq operations, and Haji Mutazz, a deputy leader. In late November, ISIS governor Radwin Talib was killed in another strike.
"It is disruptive to their planning and command and control," General Martin Dempsey told The Journal. "These are high-value targets, senior leadership."
