Iran live updates: Trump says 'I'll let you know' if ceasefire is breached

As the administration continues its efforts to ramp up international support for opening the Strait of Hormuz, Secretary of State Marco Rubio announced that the U.S. would put a new draft resolution before the United Nations Security Council to "defend freedom of navigation" in the waterway.

"The draft resolution requires Iran to cease attacks, mining, and tolling," Rubio said in a statement. "It demands that Iran disclose the number and location of the sea mines it has laid and cooperate with efforts to remove them, while also supporting the establishment of a humanitarian corridor."

Bahrain, Saudi Arabia, the UAE, Kuwait and Qatar co-authored the draft resolution, which is expected to be put to a vote "in the coming days," according to the announcement.

Last month, the U.S. put forward a similar resolution at the UNSC-but it was vetoed by China and Russia.

It's unclear whether this resolution can gain the necessary support, but earlier this week U.S. Ambassador to the U.N. Mike Waltz described it as a "narrower effort" designed to win support from Asian countries and expressed hope that, if adopted, the resolution would embolden countries to step up efforts to protect the waterway.

President Donald Trump suggested that Iran hasn't yet violated the ceasefire despite firing shots in the Strait of Hormuz, saying "I'll let you know" when it is breached.

"They didn't shoot the ships that were guarded by us," Trump said during an Oval Office event on Tuesday.

"The blockade has been amazing. It's like a piece of steel. Nobody is going to challenge a blockade," Trump said.

Defense Secretary Pete Hegseth told reporters that Iran does not control the Strait of Hormuz.

"They said they control the strait. They do not," Hegseth said.

"Iran has an ability to make that deal, but what we're demonstrating with Project Freedom is they don't control the strait. We know Iran is embarrassed by the fact that our blockade is holding, and we can run ships through, and we're going to help the world run ships through," Hegseth said Tuesday.

The fragile ceasefire between the U.S. and Iran continues to hold, with Iranian attacks being below the threshold of ending the agreement, U.S. officials told reporters on Tuesday.

"Since the ceasefire was announced, Iran has fired at commercial vessels nine times and seized two container ships, and they've attacked U.S. forces more than 10 times, all below the threshold of restarting major combat operations at this point," Gen. Dan Caine, the chairman of the Joint Chiefs of Staff, told reporters Tuesday.

The decision to restart military operations is a political one Caine and Defense Secretary Pete Hegseth did not comment on.

"Right now the ceasefire certainly holds but we're going to be watching very, very closely," Hegseth said.
