Iran live updates: 'We are not withdrawing' from south Lebanon, Israeli minister says

Iran's Islamic Revolutionary Guard Corps reiterated that no ships are allowed to pass through the Strait of Hormuz without Iran's permission in a statement Thursday.

"The false claims of the United States that ships are passing through the Strait of Hormuz normally, which indicate the desperation and helplessness of that country's army, are nothing more than lies," IRGC Spokesman Ebrahim Zolfaghari said.

"It is announced that the Strait of Hormuz, as in the past, is under the complete management and control of the Islamic Republic of Iran, and no commercial ship or tanker will be able to safely transit through this strait without the permission and supervision of the powerful Iranian armed forces," Zolfaghari said.

Iranian Foreign Minister Abbas Araghchi suggested in a post to X on Thursday that the U.S. had "miscalculated" in its war against Iran due to faulty intelligence.

"The U.S. has long miscalculated due to intelligence failures. Case in point: The war on Iran," the foreign minister wrote.

"Now, an even bigger miscalculation on the Strait of Hormuz. Worse than fake news is fake intelligence. Be careful," he added.

The Persian Gulf Strait Authority (PGSA), a newly created Iranian government agency responsible for maritime traffic in the Strait of Hormuz, appeared to reject U.S. President Donald Trump's claim that the U.S. fully controls the vital waterway.

"Claims and repeated posts by U.S. officials that the Strait of Hormuz is no longer blocked do not change the reality: the Strait of Hormuz remains blocked and will not be reopened until Iran’s conditions are accepted," the PGSA wrote in a social media post Wednesday evening.

President Donald Trump said the U.S. has "total control" of the Strait of Hormuz and then hinted that he wants the U.S. to "KEEP" the key waterway, in a social media post Wednesday.

"The U.S.A. has total control over the Strait of Hormuz. I THINK WE WILL KEEP IT!" Trump said in the post.

The president then touted the success of the U.S. naval blockade and repeated his claim that Iran's military capabilities have been diminished.

"They have No Money - Their country is 'shot.' All they have is FAKE NEWS and 300% INFLATION, and getting worse," Trump said.

"Iran is all talk and no action, the Bully of the Middle East No Longer," Trump said.
