The United States naval blockade of Iranian ports remains in place, Iran’s semi-official news agency Tasnim reported on Saturday, citing Iranian seafarers.
“The naval blockade is still in place and ships are receiving stop warnings and denial of passage from CENTCOM,” the report cited the seafarers as saying.
For his part, a top military advisor to Iran’s supreme leader accused Washington of “betraying diplomacy”.
“As expected, the US president is betraying diplomacy for the third time.
“By continuing the naval blockade and making excessive demands in negotiations, he has further proven that he is not willing to engage in talks and is pursuing other objectives,” Mohsen Rezaei wrote on X.
Moreover, Iran’s Khatam al-Anbiya Central Headquarters has reasserted Tehran’s control over the Strait of Hormuz, warning commercial and military vessels to comply with regulations governing passage through the strategic waterway.
In a statement reported on Iranian media, the command said: “The management of the Strait of Hormuz is exercised with full authority by the Armed Forces of the Islamic Republic of Iran”.
“All ships, commercial vessels, and tankers are only required to travel through the designated routes and obtain permission from the Islamic Revolutionary Guard Corps Navy. Any violation of these regulations will seriously jeopardise the security of their traffic.”
Iran also issued a warning to foreign military forces operating in the area, saying any attempt to interfere with maritime management or shipping movements would trigger a response.
In a Friday post on his social media platform Truth Social, US President Donald Trump said Iran would be required to remove any remaining mines in the Strait of Hormuz, while the US would lift its naval blockade on ships entering or leaving Iranian ports.
“Ships caught in the Strait due to our amazing and unprecedented Naval Blockade, which will now be lifted, may start the process of ‘heading home!'”
Regional tensions have escalated since the US and Israel launched strikes against Iran in February. Tehran retaliated with strikes targeting Israel as well as US allies in the Gulf, along with the closure of the Strait of Hormuz.
A ceasefire took effect on April 8 through Pakistani mediation and was later extended by Trump indefinitely.
Following stalled negotiations mediated by Islamabad, the US has imposed a blockade on Iranian ports since April 13, including those located along the strategic Strait of Hormuz.
Mediation efforts are ongoing to put an end to the conflict between the parties.
The US Navy Central Command issued an urgent maritime advisory, warning ship owners, operators and mariners about dangerous military operations underway in the Strait of Hormuz north of Oman’s Musandam Peninsula.
The Joint Maritime Information Centre advisory, dated May 29, rated the regional threat level as “CRITICAL,” citing Iranian attempts to illegally control the strategic waterway through what it described as dangerous and illegal mining that endangers ships and crews.
All mariners were advised to avoid the Strait’s Traffic Separation Scheme and instead coordinate their passage with US Naval Cooperation and Guidance for Shipping.
It also urged vessels to remain in constant radio contact with naval authorities and comply immediately with instructions from US forces.
The advisory noted a sharp warning that any vessel observed engaged in or supporting mine-laying activities would be targeted by US forces in self-defence.
A White House official said on Friday that US President Donald Trump would only pursue an Iran nuclear agreement on American terms, following a lengthy meeting in the Situation Room.
“President Trump will only make a deal that is good for America and satisfies his redlines,” the official told Anadolu.
