An Iranian military spokesman said Saturday that Tehran’s control over the Strait of Hormuz is “irreversible,” warning that the United States must accept the new status quo or face even greater costs.

“The Iranian order prevailing over the Strait of Hormuz is irreversible,” Iranian army spokesman Brig. Gen. Amir Akraminia said, according to Iran’s Fars news agency.

“Today, the Iranian order prevails in the Strait of Hormuz, and the armed forces of the Islamic Republic of Iran stand firm until this order is fully established,” Akraminia said.

He said Iran’s armed forces have the will and military capabilities necessary to enforce Tehran’s position.

“The United States has no choice but to accept the status quo, otherwise it will incur costs far greater than in the past,” Akraminia said.

His comments came as Iran said Saturday it was close to reaching an agreement with Oman on a new shipping route through the Strait of Hormuz, although Tehran said a deal alone would not be enough to fully reopen the strategic waterway.

Iranian Foreign Minister Abbas Araqchi said Iran and Oman were “very close” to an agreement on a temporary route while technical and legal issues surrounding a permanent arrangement are resolved.

But Araqchi said reopening the strait would depend on other conditions, including compensation from the United States.

The United Arab Emirates also said Saturday that Iran had attacked a carrier affiliated with its state oil company with a missile as it transited the strait. No injuries were reported. Iran did not immediately comment on the accusation.

Before the war, roughly one-fifth of global oil and gas shipments passed through the Strait of Hormuz. The conflict began with U.S. and Israeli attacks on Iran on Feb. 28.

Akraminia portrayed Iran’s position in the strait as a result of the country’s resistance to the United States, saying it had elevated Iran’s standing internationally.
