The spokesman for the Khatam al-Anbiya Central Headquarters, Lieutenant-Colonel Ebrahim Zolfaqari made the remarks on Monday following comments by US President Donald Trump that Washington could take control of the strategic waterway.

"Following previous warnings, we will under no circumstances allow the United States to interfere in the management of the Strait of Hormuz," he said.

He said the US “repeated adventurism and mischief” to interfere in the Strait of Hormuz have “seriously endangered regional security, international trade, and the passage of oil tankers and commercial vessels”.

He criticized certain regional states for cooperating with the United States, warning that such collaboration "increased the danger of war spreading across the entire region."

Zolfaqari emphasized that Iran's armed forces would “firmly confront any disruption and insecurity" created by the "aggressor and pirate US military" for the passage of commercial ships and oil tankers outside the routes designated by Iran and without authorization from the armed forces.

"The powerful actions of the Islamic Revolution Guards Corps (IRGC) and the Iranian Army in recent days are proof of this claim," the spokesman said.

In a direct warning to regional leaders, he emphasized, “Any cooperation with the United States and logistical support for that country’s aggressor army will be regarded as war against Iran's sovereignty and national security.”

“If war expands in the region, the flames of fire will engulf all regional countries,” he warned.

Zolfaqari said responsibility for any insecurity or expansion of war in the region lies with the United States and countries cooperating with its “criminal army”.

The spokesman’s remark came after Trump said on Monday that the United States would probably take over the Strait of Hormuz and should be reimbursed for controlling ​the vital waterway.

"We're going to keep the strait, and we'll probably run it. ‌We'll become the guardian of the strait. Maybe we'll call it the guardian angel of the strait. And we should be reimbursed for that," he said in a phone interview on Fox News' "Fox & Friends" program.

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 brief announcement on its X account on Sunday, the Persian Gulf Strait Authority (PGSA) said the Strait of Hormuz is closed to all transit following recent "illegal movements" by US military forces 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.

In a post on his official Instagram account on Monday, Iranian Foreign Minister Abbas Araghchi said political and technical discussions with Oman regarding the management of the Strait of Hormuz and maritime shipping traffic will continue.
