The European Union has imposed sanctions on a unit of Iran’s Islamic Revolutionary Guard Corps (IRGC) and two Iranian citizens, accusing them of obstructing freedom of navigation in the Strait of Hormuz. The EU stated that the decision was taken because commercial shipping in this vital waterway, through which nearly one-fifth of the world’s oil supply passes, has been threatened.

According to the EU, this is the first time it has used new powers to sanction Iran over restrictions on maritime freedom. The sanctions list includes the IRGC Navy’s Hormozgan provincial command, as well as two individuals—Mohammad Akbarzadeh, identified as the IRGC Navy’s deputy commander for political affairs, and Hamid Hosseini, a representative of Iran’s Oil, Gas and Petrochemical Products Exporters’ Union.

The EU’s move underscores growing concern over maritime security in the Strait of Hormuz, a critical global trade route, though further details on the sanctions’ scope or enforcement were not disclosed.
