A senior Islamic State fighter from Tunisia has been killed in a U.S. drone strike in Syria, the Pentagon said Thursday.

Tariq bin Tahar al-’Awni al-Harzi helped raise money for the Islamic State group, oversaw efforts to bring in foreign fighters and was dubbed the “emir of suicide bombers” by the U.S. State Department.

Davis said al-Harzi's death will hurt the Islamic State group's ability to move foreign fighters in and out of the region.

The U.S. officially designated al-Harzi as a terrorist last fall.

The U.S. Treasury Department imposed economic sanctions on al-Harzi and seven other individuals it said have helped finance or facilitate the movement of foreign fighters joining the Islamic State and Nusra Front jihadist groups.

Both groups have been targeted by coalition airstrikes in Syria.
