A senior U.S. official said that Tariq bin Tahar al-'Awni al-Harzi, a Tunisian, and another fighter with him were killed by a U.S. drone strike.
According to Capt. Jeff Davis, a Pentagon spokesman, al-Harzi was killed June 16 in Shaddadi.
He said that al-Harzi coordinated the use of suicide bombing attacks in Iraq, and helped with the movement of foreign fighters back and force across the Syria-Iraq border.
Davis said al-Harzi's death will hurt the ISIS's ability to move foreign fighters in and out of the region.
According to the military joint task force coordinating the operations in Iraq and Syria, there were airstrikes at four locations in Syria that day, including two near Al Hasakah, which is near Shaddadi
