WASHINGTON: A senior ISIS leader who coordinated suicide bombings and recruited funds and fighters for the militants has been killed in a coalition airstrike in Syria, the Pentagon said Thursday.

Tariq bin Tahar al-Awni al-Harzi was killed in the northern city of Shaddadi on June 16, Pentagon spokesman Navy Captain Jeff Davis said in a statement.

His brother Ali, an ISIS recruiter and person of interest in the 2012 Benghazi attack, was killed by an airstrike in Iraq a day earlier.

Washington had put a $3 million bounty on the head of Harzi, a 33-year-old Tunisian, and described him in the past as the ISIS group’s “emir of suicide bombers.”

As of late 2013, Harzi was a key figure in suicide and car bombings in Iraq, the U.S. says.

The Pentagon said his killing was a significant blow to ISIS.

“His death will impact ISIL’s ability to integrate foreign terrorist fighters into the Syrian and Iraqi fight as well as to move people and equipment across the border between Syria and Iraq,” Davis said, using an alternative acronym for the group.

The Pentagon said Harzi was also “responsible for moving people and material into Syria and Iraq” and also raised funds to recruit fighters and facilitate travel.

In addition, he supported ISIS by procuring and shipping weapons between Libya and Syria, where the militants have taken large swathes of territory.

He also worked to help raise funds from Gulf-based donors for ISIS, the United States says, including about $2 million from a Qatar-based facilitator.
