The United States expands sanctions targeting Iran’s oil and cryptocurrency-related sectors, the U.S. Treasury Department says. In a Tuesday announcement, Treasury states the action further targets the petroleum shipping network of Mohammad Hossein Shamkhani. According to the Treasury Department, the Shamkhani network continues to play a significant role in supporting Iran’s oil exports. The U.S. also alleges that the network has broadened its activities beyond shipping into wider global commodities trading. The measures are presented as part of broader U.S. efforts to pressure Iran’s ability to export oil and to disrupt associated financial and trading channels. Both outlets report the same core details: the sanctions expansion is directed at Iran’s oil sector and includes further steps involving Shamkhani’s network, with allegations that it has expanded into additional areas connected to international trade. The reports do not provide new technical specifics on the exact individuals or entities designated beyond referencing the Shamkhani network.
