The United States military has boarded another commercial vessel as part of its ongoing blockade of Iranian ports, but unlike previous incidents, the ship was permitted to continue its journey after a search.
Details of the Boarding
U.S. Central Command announced on social media that Marines boarded the Blue Star III on Tuesday but released the vessel after conducting a search and verifying that its voyage would not include a stop at an Iranian port. An accompanying video showed American forces fast-roping from a helicopter onto the ship.
The Blue Star III is at least the fourth merchant vessel to be boarded since the Trump administration initiated the blockade of Iranian shipping more than two weeks ago, but it is the first not to be taken into U.S. custody. The blockade aims to pressure Iran amid a ceasefire in the ongoing conflict, as Tehran's closure of the Strait of Hormuz—a critical waterway for energy shipments—continues to impact the global economy.
Ship's Route and Context
Data from ship tracking websites indicates that the Blue Star III departed from the Pakistani port of Qasim and was en route to Sohar, Oman. The military did not disclose what prompted the suspicion that led to the boarding. U.S. Central Command has become more assertive in arguing that the blockade is effective, despite skepticism from external experts.
The military command overseeing the Middle East has not only provided regular updates on the number of merchant ships it claims the blockade has turned away but also asserted on Tuesday that U.S. forces have cut off economic trade entering and leaving Iran.
Expansive Enforcement
Shortly after the blockade began, General Dan Caine, Chairman of the Joint Chiefs of Staff, stated that enforcement actions would extend beyond Iranian waters and the area under U.S. Central Command's control. The military also detailed a broad list of goods considered contraband, declaring that it will board, search, and seize such items from merchant vessels regardless of location. A notice specifies that any goods destined for an enemy and potentially usable in armed conflict are subject to capture at any place beyond neutral territory.
However, shipping experts such as Salvatore Mercogliano, a professor at Campbell University, have noted that Iranian ships have several methods to evade the blockade, including spoofing location tracking data or traveling through Pakistani territorial waters. Mercogliano also highlighted that the sheer volume of shipping traffic requiring screening presents a significant challenge.
Captain Tim Hawkins, a spokesman for U.S. Central Command, stated that the boarding of the Blue Star III on Tuesday demonstrates the thorough enforcement of the blockade.
