Iran said Saturday that the Strait of Hormuz is closed, citing ceasefire violations after Israel continued deadly strikes in southern Lebanon overnight.
The Islamic Revolutionary Guard Corps Navy warned ships not to approach the waterway, which Iran had committed to reopening under the interim peace deal signed this week. It said in a statement that vessels’ safety would be at risk if they did so.
Iran’s top joint military command said the closure was the “first step” in response to what were described as breaches of commitments by the U.S. and Israel, according to Iran’s semiofficial Mehr news agency.
In a social media post Saturday, President Donald Trump threatened to impose U.S tolls in the strait if a final deal with Iran isn’t reached within 60 days. The current agreement establishes toll-free travel through the strait for 60 days.
Trump did not address Iran’s assertion that the waterway is closed.
Early Saturday, Israeli strikes killed at least 16 people, including two children, according to Lebanese civil defense and media, one day after the U.S. said Israel and the militant group Hezbollah had implemented a fresh ceasefire at Trump’s request.
The continued military bombardment has threatened to derail the fragile U.S. peace talks with Iran, which specified that fighting must end on all fronts, including Lebanon. Though Israel was not a direct party to that deal, Iran has warned that it would consider Israeli strikes a violation of the terms.
Vice President JD Vance landed in Switzerland early Sunday, joining Trump’s special envoy Steve Witkoff and son-in-law Jared Kushner in the ongoing negotiations.
Speaking to reporters before he boarded the plane, Vance said that the situation in Lebanon had “calmed down” despite news reports, and added, “I think we’re going to hopefully make progress on the nuclear issue, hopefully make progress on the Lebanon ceasefire issue. Those are the two big things that I think we’re going to be focused on.”
Pakistan’s Ministry of Foreign Affairs announced “technical-level talks” will take place Sunday, with U.S. and Iranian representatives joined by mediators from Qatar and Pakistan.
Esmail Baghaei, a spokesman for Iran’s Foreign Ministry, told Iranian media the trip was a “mission to demand the fulfillment of the other side’s obligations,” adding that “negotiations for a final agreement” will begin when such obligations are implemented.
Iran’s Parliament Speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi will lead the Iranian delegation, he said, according to Iranian state TV.
Officials from Tehran and Washington were originally set to meet in Switzerland on Friday to begin 60 days of negotiations on a “final” deal, but those talks were postponed. The negotiations are meant to resolve some of the thorniest issues in the deal that are yet to be agreed upon, including Iran’s nuclear program.
Israel hit a series of towns across Lebanon’s south early Saturday, Lebanese news agency NNA reported. An airstrike on the town of Arabsalim reportedly killed three people, the agency reported, and a drone strike on the town of Deir al-Zahrani reportedly killed one person. At least seven people remain trapped under the rubble, it said. Lebanon’s army said a soldier was killed between Kfar Rumman and Nabatieh in southern Lebanon.
A previous wave of strikes on Friday killed 83 people, Lebanon’s Ministry of Health said.
A statement from the Israel Defense Forces said Hezbollah had breached the ceasefire and “launched more than 50 projectiles toward IDF soldiers operating in southern Lebanon” overnight, and that Israel had attacked what it described as Hezbollah targets in response. “The IDF remains committed to the ceasefire agreement,” the statement said.
Hezbollah said it had “adhered to the ceasefire since Friday evening,” accusing Israel of making false claims to justify its attacks in an effort to “sabotage the agreement” between Iran and the U.S.
IDF spokesperson Brig. Gen. Effie Defrin said Friday that Israeli forces will continue to operate in southern Lebanon and “do whatever is necessary to protect our civilians.”
U.S. spy agencies believe that Israel will likely continue to launch attacks against Hezbollah in Lebanon, potentially jeopardizing the tentative peace deal, according to a source with knowledge of the intelligence assessments.
Israel’s continued strikes on Lebanon have worsened a widening rift between the Trump administration and Prime Minister Benjamin Netanyahu and his far-right allies, who have criticized the Iran deal as not in Israel’s interest and agitated for more strikes on Lebanon. Netanyahu is also facing a crucial election in October and will likely need the support of the Israeli far right to stay in power.
“Netanyahu is in a challenging political spot,” Jonathan Panikoff, a former career intelligence officer now at the Atlantic Council think tank, told NBC News in an email. “When combined with the broad view that Iran has emerged strategically stronger, Netanyahu finds himself trapped.”
Netanyahu’s vow to occupy southern Lebanon and Israel’s decision to strike both Iran and Lebanon while an initial deal was being hammered out repeatedly delayed talks, fueling frustration among U.S. officials.
Vance hit out at Israeli officials Thursday, saying that Israel does not appreciate American support.
Despite the rising tensions over Lebanon, there had been hope that ships trapped in the Persian Gulf will be able to transit through the Strait of Hormuz since the deal was signed. Industry experts have warned, however, that it could take weeks for the shipping traffic to fully normalize, given that the threat of mines still needs to be cleared.
In a statement on X that did not acknowledge the apparent closure of the strait, U.S. Central Command said that 55 merchant ships transited the waterway on Saturday, “moving large amounts of cargo and more than 17 million barrels of oil to global markets.”
U.S. forces “remain present and vigilant to ensure all aspects of the agreement with Iran are adhered to, obeyed, and in full force and effect,” the statement said.
The White House and Israeli prime minister’s office did not immediately respond to requests for comment on the Iranian declaration.
