U.S. blockade on Iranian ports restarts as Trump angles for control over Strait of Hormuz

Iran’s embassy in the U.K. said Monday that the Islamic Republic had “established a temporary safe & secure maritime corridor, free of technical & military barriers” through the Strait of Hormuz, indicating a reopening of the crucial shipping lanes from Tehran’s perspective. 

It was not clear if the embassy’s post on social media, in referring to a lack of “technical & military barriers,” was suggesting an easing of Iran’s own demand for ships to coordinate with its military to use a northern route, close to its coast, through the strait, or speaking about a more southerly route that the U.S. has urged vessels to use over the last couple weeks. 

The U.S. military on Sunday contradicted a claim by Tehran’ that the Strait of Hormuz was again closed, insisting that “Iran does not control” the vital shipping lanes amid an ongoing disagreement between the nations over commercial access to the waterway.

In its statement, the embassy accused the U.S. of having “done nothing but violate the MoU since day one,” specifically by “pushing vessels toward a dangerous southern parallel route” through the strait, close to Oman’s coast, that it called “not only legally questionable but also unsafe, unreliable, and prone to accidents.”

Iran attacked several ships attempting to use that southern route last week, and on Saturday it also struck a container vessel near the western entrance to the strait, prompting the U.S. to launch multiple rounds of airstrikes on Iranian targets. 

Iran has long argued that the vaguely worded MoU signed in mid-June with the U.S. gave it the right to control shipping through the strait, and it balked at the U.S. government and military’s calls for ships to use the southern route close to Oman, which President Trump has insisted is open.

“U.S. military aggression, including attacks on Iran’s port & tower infrastructure, has turned the Strait of Hormuz into a tense, high-risk zone for maritime traffic,” the Iranian embassy in London said Monday, adding a jab that appeared to be directed at Oman: “Those who enabled this perilous situation must reconsider their stance, if they truly seek safe passage through the Strait of Hormuz. Security is a two-way street.”
