The United States has imposed new sanctions targeting Iran's oil smuggling network, blacklisting 29 vessels and their management companies accused of facilitating the transfer of hundreds of millions of dollars in Iranian petroleum products. American officials say these ships are part of a so-called 'shadow fleet' that uses deceptive tactics to disguise shipments and evade international sanctions. The latest measures also target companies and individuals in several countries, including the United Arab Emirates, Panama, and Egypt, as Washington intensifies its campaign to restrict Tehran's access to petroleum revenue. These actions are part of ongoing efforts to pressure Iran over its military and nuclear ambitions, with more than 180 vessels sanctioned since January.
