Move comes as Tehran and Washington implement preliminary deal to reopen Strait of Hormuz.
Several Iranian commercial vessels, including oil tankers and cargo ships, successfully crossed what Iranian state media described as a US naval blockade line in the Gulf of Oman on Monday without encountering any interference from American forces.
The development marks a significant de-escalation in maritime tensions that have gripped the region for months. Iranian media outlets, including Press TV and Tasnim, reported that at least three oil tankers and two cargo ships carrying essential goods passed through the area, declaring it as evidence that the US-imposed restrictions had effectively ended.
US-Iran Deal Reopens Strait of Hormuz, Ends Naval Blockade:
The United States established a naval blockade on Iranian ports in April 2026 as part of its military campaign against Iran. The measure severely restricted shipping to and from Iranian ports, particularly through the strategic Strait of Hormuz, a critical chokepoint for global oil supplies.
However, a preliminary memorandum of understanding reached between the US and Iran in recent days has paved the way for the reopening of the Strait of Hormuz and the lifting of the naval blockade. The framework deal, which includes a ceasefire extension and further talks, appears to be taking effect on the ground.
US President Donald Trump stated that ships were beginning to move freely through the strait, describing the southern route as “safe and secure.”
Iranian Vessels Cross Gulf of Oman Amid Diplomatic Breakthrough:
The successful transit of Iranian vessels without incident is being hailed by Iranian officials as a victory for resistance against what they called an “illegal blockade.” It also signals a potential return to normal commercial shipping in one of the world’s most vital energy corridors, which handles around 20 percent of global oil trade.
Analysts caution that while this marks a positive step, full implementation of the agreement remains fragile. Broader regional issues, including the situation in Gaza, Lebanon, and ongoing sanctions relief negotiations, continue to influence stability in the Gulf.
The Gulf of Oman and Strait of Hormuz have seen repeated incidents over the past months, including US forces disabling several vessels attempting to breach the blockade. Monday’s uneventful crossings suggest a rapid shift following the diplomatic breakthrough.
