US reroutes newly sanctioned oil tanker as Iran blockade continues

Just one day after being added to the US sanctions list, the oil tanker M/V Sevan was intercepted in the Arabian Sea and escorted back to Iran as part of the US naval blockade, US Central Command reported in a Facebook post today.

The command stated that, as of this Saturday (25), 37 ships had been redirected by the US Navy, while the Trump administration maintains the blockade of Iranian ports, amid diplomatic negotiations between the two countries.

The blockade began after a ceasefire in early April and included the seizure by American armed forces of three ships that did not comply with orders to return.

The Sevan was one of 19 ships hit by sanctions on Friday (24), as part of what the US Treasury Department called “Economic Fury”, the campaign to pressure Tehran, coinciding with US military strikes that began in February.

The agency accused the ship of having transported Iranian propane and butane, products subject to sanctions, in 2025.
