President Donald Trump acknowledged that Iran is seeking to close the Strait of Hormuz again, saying Iran "got a little cute."

“They can't blackmail us,” he said.

“We have very good conversations going on. It's, it's working out very well. They got a little cute, as they have been doing for 47 years, and nobody ever took them on. We took them on,” Trump said.

The president then appeared to brag that the U.S. was benefiting from the lack of oil transiting through the strait — touting that ships were coming to the U.S. now instead.

“In fact, a lot of the ships are coming up to Texas I don't know if you know, in Louisiana, the ships are coming up. They got used to it. Maybe they'll keep doing it," Trump said.

A container ship reported being struck by an "unknown projectile" causing damage in the Strait of Hormuz, the United Kingdom Maritime Trade Operation said in a warning Saturday.

The projectile struck the cargo ship 25 nautical miles northeast of Oman causing "damage to some of the containers, no fires or environment impact reported," the warning said.

Earlier the UKMTO reported a tanker was fired upon by two Iranian Revolutionary Guard Corps "gun boats."

It comes after a spokesperson for the Iranian Armed Forces, said “The Strait of Hormuz has returned to its previous state.”

Iran's supreme leader, Ayatollah Mojtaba Khamenei, said in a statement on Saturday that his country was "now courageously defending the land, water, and flag that belong to it."

Khamenei, who has not been seen publicly since the beginning of the war, said in the statement that Iran in fighting against the U.S. and Israel was "battling against the two leading armies of disbelief and Arrogance."

"And the Islamic Army has exposed those armies' weakness and abjectness to the world," the statement said. "In the same way that its drones strike the US and the Zionist murderers like lightning, its valiant navy is also ready to inflict new bitter defeats on its enemies."

Two Iranian boats approached and fired on a tanker off Oman’s coast on Saturday morning, the U.K. Maritime Trade Operations organization said.

The Islamic Revolutionary Guard Corps ships were said to have approached a tanker about 20 nautical miles off the northeastern coast of Oman, according to the UKMTO, a maritime security monitoring group.

"The Master of the Tanker reports being approached by 2 IRGC gun boats, no VHF challenge that then fires upon the tanker," UKMTO said, describing a typical emergency vessel-to-vessel radio communication or "challenge."

The tanker and its crew were reported safe, UKTMO said, adding that an authorities were investigating.
