ERBIL, Kurdistan Region of Iraq - Iran's armed forces are exercising “full authority” over the Strait of Hormuz, the Khatam al-Anbiya Central Headquarters said Saturday, requiring commercial vessels and oil tankers to obtain authorization from the Islamic Revolutionary Guard Corps (IRGC) Navy before transiting the waterway.

In a statement, the headquarters said that, under the unified management of the strait, “all ships, commercial vessels, and oil tankers are required to navigate only through designated routes and obtain authorization from the IRGC Navy.”

The military command warned that violations of the regulations could endanger the security of maritime transit and cautioned foreign naval forces against interfering in the management of the waterway or disrupting traffic through it.

“Any attempt by military vessels to interfere in the management of the Strait of Hormuz or disrupt maritime traffic will be targeted by the Armed Forces of the Islamic Republic of Iran,” the statement said.

On Friday, Trump said Iran must agree to several conditions to advance toward a peace agreement, including never obtaining a nuclear weapon, fully reopening the Strait of Hormuz, removing all mines and destroying its enriched uranium stockpile, while announcing that the naval blockade on Iranian ports “will now be lifted.”

Earlier on Saturday, senior IRGC commander Mohsen Rezaei accused US President Donald Trump of “betraying diplomacy for the third time” and said that by “continuing the naval blockade and being greedy in negotiations, the US president had shown he was not interested in negotiation and is pursuing other goals.”

Iranian media also reported that the blockade remained in place despite Trump's announcement.

The US Central Command (CENTCOM) said its forces disabled a “Gambia-flagged vessel attempting to sail toward an Iranian port” on Friday, after issuing more than 20 warnings.

CENTCOM said a US aircraft disabled the ship by firing a Hellfire missile into its engine room after the crew failed to comply, adding that the vessel “is no longer transiting to Iran.”

It added that five commercial vessels have been disabled and 116 others diverted as part of efforts to enforce the blockade on Iranian ports.
