The United States imposed new sanctions targeting a network involved in transporting Iranian oil, the State Department announced Friday. The measures designate 15 entities, 14 vessels, and two individuals linked to what Washington describes as Tehran’s “shadow fleet,” a covert shipping network used to circumvent existing sanctions. According to U.S. officials, revenue generated through these operations supports militant groups and contributes to regional instability. The sanctions were announced as U.S. and Iranian officials met in Oman for mediated talks aimed at easing tensions over Tehran’s nuclear program, reflecting parallel tracks of diplomatic engagement and economic pressure amid broader regional concerns over escalation.
