On May 28 the U.S. Treasury Department sanctioned eight vessels and more than 15 entities involved in transporting Iranian crude oil and petroleum products linked to the military. The measures target specific tankers including the Flora, Hauncayo, and Ill Gap, plus firms such as Worth Seen Energy Limited, Symphony Shipping and Maritime Management Inc, and Mehdiyev Trading Co. Treasury Secretary Scott Bessent stated the actions aim to prevent increased Iranian oil revenue for military reconstitution.
