A bill has been introduced in the U.S. House of Representatives to sanction a top Iranian terror proxy group in Iraq that has targeted U.S. personnel in Baghdad.

Rep. Joe Wilson (R-S.C.) introduced the measure on Thursday that would for the first time designate the Badr Organization, which is tied to Iran’s Islamic Revolutionary Guard Corps, as a terrorist group.

The Washington Free Beacon first reported on the bill.

The Badr Organization has been responsible for the lethal attacks on U.S. embassy personnel stationed in Baghdad, including one last year that led to the U.S. drone strike in January year that killed Maj. Gen. Qassem Soleimani, who commanded the Badr group.
