TEHRAN/WASHINGTON/LONDON – Despite US President Donald Trump's claim that he had lifted a naval blockade on Iran, Iranian ships are still being barred from passing through the Strait of Hormuz, the semi-official Tasnim news agency reported Saturday.

Citing Iranian sailors, the report said the restrictions remain in place and vessels continue to receive warnings from US Central Command (CENTCOM) not to enter the area.

Trump said in a post on Truth Social on Friday that the US naval blockade "will now be lifted."

In the same post, he outlined conditions for a possible deal with Iran, saying Tehran must agree never to obtain a nuclear weapon. He also said the Strait of Hormuz should be "immediately open," with unrestricted shipping in both directions, and that any water mines would be removed. 

Trump added that Iran's enriched uranium stockpiles would be located, in coordination with Iran and the International Atomic Energy Agency, and destroyed. Iran has said nuclear issues are not part of the current stage of talks.

Also on Saturday, CENTCOM said that it disabled a Gambia-flagged maritime vessel attempting to sail toward an Iranian port on Friday.

"CENTCOM forces observed M/V Lian Star transiting international waters toward an Iranian port on the Gulf of Oman and issued more than 20 warnings while informing the vessel it was in violation of the US blockade," according to a statement by CENTCOM on social media.

"A US aircraft disabled the vessel by firing a Hellfire missile into the ship's engine room after Lian Star's crew failed to comply," said CENTCOM's statement. "The ship is no longer transiting to Iran."

CENTCOM said in the statement that the US military has disabled a total of five commercial vessels and "redirected" 116 vessels during the naval blockade.

Meanwhile, Iran's main military command, Khatam al-Anbiya Central Headquarters, said on Saturday the Iranian armed forces are exercising management over the Strait of Hormuz with full authority, the official news agency IRNA reported.

Making the remarks in a statement, the headquarters stressed that for passage through the waterway, all vessels, including commercial ships and oil tankers, are required to solely travel through the routes designated by Iran and obtain permission from the Navy of the Islamic Revolution Guard Corps (IRGC).

The headquarters warned that Iran's armed forces will respond to any action by military vessels to interfere in the strait's management or disrupt traffic through it.

The IRGC's Navy said Saturday that 20 vessels crossed the strait within the past 24 hours in coordination with its forces and Iran's maritime authorities, according to the semi-official Fars news agency.

Fars quoted officials of the IRGC's Navy as saying that the vessels were granted permission to pass through the strait owing to their countries' needs for commodities such as chemical fertilizers.

Iran tightened its grip on the strait beginning Feb 28, when it barred safe passage of vessels belonging to or affiliated with Israel and the United States following joint strikes on Iranian territory.

The IRGC’s Navy warned on Saturday that any US interference in the "management" of the Strait of Hormuz would be met with a "strict military response."

According to recordings from a public maritime radio channel provided to Xinhua by crew members aboard vessels stranded near the strategic waterway, the IRGC Navy issued a warning to ships operating in the Persian Gulf and the Gulf of Oman, stating that the Strait of Hormuz remains closed and that transit is permitted only with authorization from the IRGC Navy and through routes designated by the Islamic Republic of Iran.
