Iran live updates: Rubio says 'significant progress' made in Iran talks

Secretary of State Marco Rubio said on Sunday that the U.S. has made "significant progress" in discussions related to Iran, while stressing the "ultimate goal is that Iran can never have a nuclear weapon."

Speaking during his visit to India in a press conference with Indian External Affairs Minister Subrahmanyam Jaishankar, Rubio said that additional developments could come later on Sunday.

Rubio added that the administration has worked with Gulf regional partners over the last 48 hours on a possible framework aimed at keeping international waterways open and addressing concerns surrounding Iran's nuclear ambitions.

"We think we've made some progress on the outline of something that, if it works, could give us that outcome," Rubio said, while cautioning that any agreement would still require "full Iranian acceptance, and then compliance."

He also condemned Iranian threats against commercial shipping routes, calling such actions "illegal under any concept of international law."

Rubio defended President Donald Trump's record on Iran, stating "there is no one who has been stronger on this issue than President Trump," dismissing suggestions that the administration would agree to any arrangement that strengthens Iran's nuclear capabilities.

"The idea that somehow this president, given everything he's already proven he's willing to do, is going to somehow agree to a deal that ultimately winds up putting Iran in a stronger position when it comes to nuclear ambitions is absurd," Rubio said.

Rubio closed his remarks by expressing cautious optimism, saying "perhaps there is the possibility that over the next few hours the world will get some good news."

President Donald Trump said Saturday that a framework for a peace deal with Iran will be announced shortly and it will include opening the Strait of Hormuz.

In a lengthy social media post, the president said he spoke with several Middle Eastern leaders and "an Agreement has been largely negotiated, subject to finalization between the United States of America, the Islamic Republic of Iran, and the various other Countries."

"Final aspects and details of the Deal are currently being discussed, and will be announced shortly," he said.

The post added: "In addition to many other elements of the Agreement, the Strait of Hormuz will be opened."

Secretary of State Marco Rubio spoke with reporters following his meeting with India’s Prime Minister Modi earlier Saturday, saying negotiations remain ongoing but that there "may be news" Saturday or in the coming days.

"There may be news later today. I don't have news for you at this very moment, but there might be some news a little later today, there may not be. I hope there will be, but I'm not sure yet," Rubio said.

Rubio stressed that "some progress" has been made with respect to Iran, before emphasizing the U.S. position on Iran not having a nuclear weapon, opening the Strait of Hormuz without a toll, and turning over enriched uranium.

"Even as I speak to you now, there's some work being done. There is a chance that whether it's later today, tomorrow, and a couple days, we may have something to say, but this issue needs to be solved as the president’s said, 'one way or the other'," Rubio said.

U.S. forces have now re-directed 100 commercial vessels as part of its blockade against Iran, according to U.S. Central Command.
