In a brief announcement on its X account on Sunday, the Persian Gulf Strait Authority (PGSA) said that passage through the Strait of Hormuz is currently unavailable amid recent US military activities in the region.

"Due to recent unlawful movements by United States military forces in the region, transit through the Strait of Hormuz is currently not possible," it added.

It clarified that vessel traffic would remain suspended until stability and calm are restored in the area.

"As soon as stability and calm are restored, all requests will be reviewed according to scheduling and the necessary permits will be issued,” the authority emphasized.

The PGSA noted that the only legitimate channel for obtaining transit permits is its official website, PGSA.ir, and advised vessels to follow its social media account on the X platform for real-time updates.

Iran shut down the chokepoint to enemies and their allies shortly after the US and the Israeli regime launched their unprovoked aggression against the Islamic Republic on February 28.

It began exercising far stricter controls after Donald Trump announced continuation of an illegal naval blockade of Iranian vessels and ports despite a ceasefire that the US president, himself, had declared on April 7.

In a statement on Saturday, the Islamic Revolution Guards Corps (IRGC) Navy announced the closure of the Strait of Hormuz “until further notice,” saying the waterway will remain closed until the United States ends its intervention in the region.

The IRGC Navy said the measure had been taken “in light of the security situation resulting from the unlawful intervention of foreign powers.”

In May, Iran officially launched the PGSA to govern maritime traffic through the strategic strait, warning that vessels must coordinate their transits with Iranian authorities and use routes defined by Tehran.

In June, Iran and the United States reached an understanding aimed at ending the cycle arising from the unprovoked aggression. Washington then alleged to have lifted the blockade, but continues military interference in the waterway.
