Iran live updates: 8 Marines hurt in ship attack in Strait of Hormuz

President Donald Trump announced "major combat operations" against Iran on Feb. 28, with massive joint U.S.-Israeli strikes targeting military, government and infrastructure sites.

Delegations from the U.S. and Iran entered negotiations in June aimed at a war-ending deal based on a memorandum of understanding signed by both countries.

Those talks broke down as the U.S. and Iran continued to exchange strikes, with the strategic Strait of Hormuz as the primary flashpoint. Trump then said in August that the U.S. would launch a "crushing economic operation" to force Tehran into submission.

When asked about the progress of Monday's mediated talks between the U.S. and Iran, President Donald Trump said, "We're going to win this as far as I'm concerned. It's going to be one way or the other. It's going to be -- it's going to go pretty quickly, too."

Trump continued to promise gas prices would come down after the war with Iran ends. "We have the best economic numbers we have. Iran will never have a nuclear weapon. We're going to win that war very, very soon. It'll be over. And the gas prices will come tumbling down," Trump said. -ABC News' Isabella Murray and Michelle Stoddart

After President Donald Trump rejected a proposal from Iran over the weekend, U.S. officials said he remains open to offering the country sanctions relief and releasing its frozen assets in exchange for concrete progress toward a nuclear deal. Trump confirmed U.S. and Iranian officials spoke via mediators on Monday. The Trump administration has always said Iran would receive substantial financial rewards if it walked away from its nuclear program, and under June's memorandum of understanding, the U.S. promised to roll back all sanctions as part of a verifiable, long-term nonproliferation deal. Iran has not indicated it's willing to bring the nuclear issue into negotiations at this point. -ABC News' Shannon Kingston

Eight Marines were recently hurt in an Iranian attack on a ship operating in the Strait of Hormuz, though the injuries were not significant, a U.S. official confirmed to ABC News.

The United Kingdom Maritime Trade Operations tracked that a commercial vessel was struck by "an unknown projectile" on Sept. 14 and no injuries were reported at the time. NBC News was first to report the previously undisclosed injuries to the Marines. U.S. Central Command declined to comment on the report. -ABC News' Luis Martinez

U.S. Central Command on Monday disputed a claim from an Islamic Revolutionary Guard Corps commander asserting that Tehran enjoys "full control over the Strait of Hormuz." "This is FALSE," CENTCOM said in a post to X. "Iran has no navy because American forces sank it. And Iran does not control the Strait of Hormuz as evidenced by the thousands of ships that have passed through freely along with more than 1 billion barrels of oil just over the past few months," CENTCOM said.

Saudi Arabia's Foreign Minister Prince Faisal bin Farhan arrived in Washington early on Monday morning ahead of talks with Secretary of State Marco Rubio, according to the Saudi foreign ministry. The two will "review bilateral relations and discuss regional and international developments," the ministry said in a statement. Saudi Arabia is currently in an escalating conflict with the Iran-aligned Houthis in Yemen, as it supports the internationally recognized Yemeni government's military in its fight against the group. -ABC News' Victoria Beaule

Iranian Foreign Minister Abbas Araghchi asserted that Tehran is prepared to resume war with the U.S. and said it will stand firm "even if it comes to a doomsday war." Asked whether diplomacy has failed, Araghchi told NBC's "Meet the Press" Sunday that there is always hope but repeatedly cast doubts on the Trump administration's intentions.

"[T]here is always hope for diplomacy. But we have no reason, to be honest with you, we have no reason to come back to diplomacy and engage with this administration once again, because of their behavior in the past two years," Araghchi said . "We stand firm in the face of any aggression against us, even if it comes to a doomsday war," he said, adding "at the same time, we are ready for diplomacy." "Now there is a very reasonable plan on the table. If they reject it for no reason, this is their fault," Araghchi said. "We are ready for diplomacy. We are ready for war at the same time," he added. -ABC News' Nicholas Kerr

President Donald Trump said that he expects more talks with Iran to occur this week as he continues to claim the country wants to make a deal to end the war, an agreement that has continued to elude the president. "I expect more talks with Iran [this week]. They want to make a deal, but it is not the deal that I want to make. It is what we would have maybe agreed to a year ago. They overplayed their hand," Trump told Axios in a piece published Sunday.

Asked if he was considering new strikes against Iran, Trump responded: "I am always thinking about it." The president also claimed that more than 20 million barrels of oil transited the Strait or Hormuz over the weekend, which he said was the largest since the start of the war. "Last night, we took a record amount of oil out from the Hormuz Strait — more than we took out before the war," Trump told reporters on the White House South Lawn earlier Sunday. -ABC News' Nicholas Kerr
