Iran shuts Strait of Hormuz amid Israel strikes on Lebanon; US-Iran talks to begin Sunday in Switzerland

Iran escalated tensions with the US by announcing the closure of the Strait of Hormuz and casting doubt on nuclear negotiations in Switzerland, citing Israeli attacks and American “bad faith.” Pakistan and Qatar are mediating technical-level talks, while US negotiators are already in Switzerland.

Tyre (Lebanon): Iran dealt two quick blows to the interim agreement with the United States on Saturday, angered by Israel’s continued attacks in Lebanon, saying it had closed the Strait of Hormuz and also announcing that while its negotiators were going to Switzerland for talks, not much is likely to happen there.

Key mediator Pakistan, meanwhile, said the technical-level talks will begin on Sunday in Bürgenstock, Switzerland, with Qatari mediators also participating.

In Tehran’s first salvo, Iran’s joint military command said the strait had been closed, citing the Israeli attacks and US “bad faith” and “clear breach of its commitments” by failing to end the war. Its statement on state television warned that “if the aggression continues, subsequent steps have been planned.”

Shortly after that, the state broadcaster announced that Iran’s negotiating team was heading to Switzerland “in the coming minutes,” a trip that had been originally planned for Friday.

Foreign Ministry spokesperson Esmail Bagahei, however, signalled that little might happen until Iran feels the US is living up to the deal.

“This trip is therefore about demanding that the other side fulfil its obligations,” he said, adding that negotiations toward a final agreement will begin only once key commitments are upheld. If they are not, he said, “then the memorandum of understanding as a whole will be jeopardised.”

In Washington, Vice President JD Vance confirmed on Saturday that the top US negotiators — Jared Kushner and Steve Witkoff — were already in Switzerland and have been working through technical details of the anticipated negotiations on Iran’s nuclear program.

Vance told Fox News that he expects to leave for Switzerland “sometime the next couple of days” but acknowledged that “it’s always a delicate coordination dance.”

Meanwhile, the global economy braced for more uncertainty. Ships had begun transiting the strait after the interim US-Iran agreement was signed earlier in the week, a milestone that has left plenty of questions unanswered.

Israeli attacks in Lebanon kill at least 16

Earlier Saturday, Israeli strikes on southern Lebanon killed at least 16 people, including two children, hours after reports emerged of a ceasefire agreement there. Seven people remained trapped under the rubble after the strikes hit the southern city of Nabatiyeh and nearby villages, Lebanon’s National News Agency said.

The death toll in the latest war between Israel and Hezbollah has now surpassed 4,000, Lebanon’s health ministry later announced.

Mediators were scrambling to halt the fighting between Israel and the militant Hezbollah group after a heavy exchange on Friday killed at least 47 people in Lebanon and four Israeli soldiers.

An Israeli military official said Hezbollah had fired more than 50 projectiles at Israeli forces in southern Lebanon overnight. The official spoke anonymously in line with regulations. Israel’s army said it struck dozens of Hezbollah targets and militants in southern Lebanon, including Hezbollah command centres.

On Friday, the Israeli ambassador to Washington, Yechiel Leiter, said Israel “remains firmly committed to an immediate ceasefire” if Hezbollah honours the agreement and ceases hostilities.

On Saturday, Hezbollah said it had committed to the ceasefire but blamed Israel for violating it several times Friday night. A statement by the group’s military wing said it would abide by the ceasefire but would also repel attacks by Israeli troops.
