The Iranian ship that was seized by the U.S. after it tried to run the U.S. blockade has been transferred to Pakistan for repatriation to Iran, along with its crew, a spokesman for U.S. Central Command told ABC News.

"Today, U.S. forces completed the transfer of 22 crew members of M/V Touska to Pakistan for repatriation," Captain Tim Hawkins said. "Six other passengers were already transferred to a regional country for repatriation last week."

Iran state media identified the six as family members of some of the crew.

"Custody of Touska is currently being transferred back to its original ownership after the ship was intercepted and seized when attempting to violate the U.S. naval blockade against Iran last month," Hawkins said.

When the crew of the Touska ignored six hours’ worth of warnings from U.S. ships on April 19, a destroyer fired several rounds at the container ship's engine room, Gen. Dan Caine, the chairman of the Joint Chiefs of Staff, said at a Pentagon news conference on April 24. The ship was later boarded by U.S. Marines, who seized the ship.

President Donald Trump announced on Sunday that he's ordered U.S. personnel to safely guide ships and crews from countries that are not involved with the Iran war out of Strait of Hormuz, which is currently subject to a naval blockade.

This "humanitarian gesture," which Trump called "Project Freedom," will begin Monday morning "Middle East time," he wrote.

"The Ship movement is merely meant to free up people, companies, and Countries that have done absolutely nothing wrong -- They are victims of circumstance," the president wrote. "This is a Humanitarian gesture on behalf of the United States, Middle Eastern Countries but, in particular, the Country of Iran."

Trump claimed that his "representatives" were having "very positive discussions" with Iranian leadership, despite the fact that he said earlier Sunday that he reviewed their most recent peace proposal and that it is "not acceptable."

He said these discussions "could lead to something very positive for all" but warned that if Iran interferes with these safety efforts, they will "have to be dealt with forcefully."

Iran's Islamic Revolutionary Guard Corps issued a statement via the state-run Press TV claiming that the U.S.' room for decision-making "has narrowed" amid the ongoing negotiating stalemate.

In its statement, the IRGC claimed that Tehran has set the Pentagon a deadline to lift its blockade of Iranian ports. It also claimed that the global tone of conversation on the conflict has shifted "against Washington," citing critical statements on the war from China, Russia and Europe.

President Donald Trump, the IRGC said, must choose between "an impossible military operation or a bad deal" with Iran.

Mohsen Rezaee, the top military adviser to Iran's Supreme Leader Mojtaba Khamenei, said in a post to X on Sunday that Tehran is prepared to create a "graveyard" of American military vessels if fighting resumes.

"The U.S. is the only pirate in the world that possesses aircraft carriers. Our ability to confront pirates is no less than our ability to sink warships," Rezaee wrote.

"Prepare to face a graveyard of your carriers and forces, just as the wreckage of your aircraft was left behind in Isfahan," Rezaee added, referring to the U.S. aircraft lost in the operation to recover a downed F-15 crewmember inside Iran in April.

Secretary Marco Rubio suggested to Fox News in an interview on Monday that Iran's peace proposal falls short of the U.S. conditions for ending the war, now entering its third month.

Two officials familiar with the matter told ABC News that the Iranian proposal consists of a loosening of Tehran's grip on the Strait of Hormuz in exchange for the lifting of the U.S. blockade. Talks on Iran's nuclear program would then be pushed back to an unspecified future date, Tehran's proposal suggested.

Rubio, though, said the nuclear issue was at the heart of the U.S. position. "The nuclear question is the reason why we're in this in the first place," Rubio said.

Rubio also said the U.S. would not allow Tehran to retain control over the Strait of Hormuz, or to continue to charge tolls to shipping passing through.

"Those are international waterways. They cannot normalize, nor can we tolerate them trying to normalize, a system in which the Iranians decide who gets to use an international waterway and how much you have to pay them to use it," he said.

Rubio underscored U.S. concerns about the regime's ability to agree to a deal and the status of new Supreme Leader Mojtaba Khamenei.

"One of the impediments here is that our negotiators aren't just negotiating with Iranians. Those Iranians then have to negotiate with other Iranians in order to figure out what they can agree to, what they can offer, what they're willing to do, even who they're willing to meet with," Rubio said.

Asked whether he believed Mojtaba Khamenei was still alive, Rubio replied, "We have indications that he is. Obviously they claim that he is. We don't have evidence that he's not."

"I think the question between alive and in power are two different questions. You can be alive -- but I think the unresolved questions here are does he have the same credibility as his father did," Rubio said.

Rubio also suggested that the Iranian proposal may not have the backing of all factions jostling for influence in Tehran. "I think there are still questions about whether the person submitting it had the authority to submit that offer," he said.

Nonetheless, Rubio said he believed the Iranians "are serious about getting themselves out of the mess that they're in."
