A sanctioned Iranian tanker carrying about 500,000 barrels of liquefied petroleum gas slipped past the US naval blockade and delivered its cargo to China, according to United Against Nuclear Iran (UANI), which says it filmed the ship at a Malaysian anchorage along the way.

On October 8, the US Treasury Department sanctioned the tanker as one of 17 shadow-fleet vessels, saying the Comoros-flagged ship, owned by Marshall Islands-based Gravion Maritime Company, had transported more than 2 million barrels of Iranian propane and butane since September 2025.
