Several oil tankers listed under U.S. sanctions have begun entering the Persian Gulf region despite a strict American naval blockade. According to vessel monitoring group TankerTrackers.com, at least two ships managed to breach the U.S. Navy’s perimeter. The group reported on social media platform X that a tanker named ‘Vina/Valley’ (9157478) crossed the blockade boundary on Wednesday. The vessel is known for regularly supplying Iranian liquefied petroleum gas to Yemen’s Houthi rebels.

TankerTrackers.com added that alongside the smaller vessel, a larger Iranian oil tanker also reached the area, though both ships were currently empty. The United States has maintained a tight naval blockade around Iranian ports to pressure Tehran into ending the conflict and returning to negotiations. The arrival of these tankers occurred amid this heightened enforcement.

The report, sourced from Al Jazeera, highlights continued maritime tension in the region as sanctioned Iranian-linked vessels test the limits of U.S. restrictions.
