The United States and six Gulf countries imposed joint sanctions on entities connected with Iran's illicit financing of paramilitary groups in the Middle East. The sanctions are the largest ever undertaken by the Terrorist Financing Targeting Center (TFTC), a coalition of Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates, and the United States. The action primarily targets a multibillion-dollar network of Iranian companies, banks, and funds supporting the Basij Resistance Force, which has ties to Iran's Islamic Revolutionary Guard Corps (IRGC). All of the entities were previously blacklisted by the United States, but the new sanctions will require TFTC members to close the targets' local offices, including Iran's Mellat Bank. The TFTC also sanctioned four individuals linked to Hezbollah.
