US blocks 23 tankers after Iran's missile attack on Israel

The US Treasury expanded sanctions on Iran's petroleum and petrochemical sectors on 11 October, designating ten entities and 17 vessels, while the State Department designated six entities and six more vessels. The Maritime Executive reports that the action responded to Iran's 1 October attack on Israel and targeted shipping networks moving oil for the National Iranian Oil Company and Triliance Petrochemical. According to the report, the operators were based in countries including the UAE, Hong Kong, China, Malaysia and Liberia, and the oil ultimately reached refineries in China. Treasury Secretary Janet Yellen said the measures target Iran's efforts to channel energy revenues into 'deadly and disruptive activity'.
