US Marines have boarded the M/T Wen Yao in the Gulf of Oman as part of the enforcement of a US naval blockade on Iranian ports. This military action comes amid a broader escalation, with US forces conducting strikes on Iranian infrastructure, including bridges and rail lines. The blockade, announced by President Donald Trump on July 13, 2026, aims to pressure Iran into reopening the Strait of Hormuz and resolving a prolonged conflict. The 11th Marine Expeditionary Unit’s involvement underscores the US’s commitment to enforcing the blockade with direct measures, having already redirected multiple vessels in the region.
