    [ZURICH/DUBAI/WASHINGTON] US Vice President JD Vance arrived in Switzerland on Sunday (Jun 21) for peace talks with Iran as both nations seek a durable end to their war while disagreeing over Iran’s claims that it had closed the vital Strait of Hormuz.

    Although the US and Iran had agreed to a 60-day ceasefire while negotiations take place, Teheran’s Islamic Revolutionary Guard Corps (IRGC) on Saturday declared the Strait of Hormuz shut, though the US military said commercial vessels had continued operating in the waterway.

    Those developments could complicate talks in which both sides seek to advance an interim deal brokered by Pakistan and signed on Jun 17 by US President Donald Trump and Iranian President Masoud Pezeshkian to end their almost four-month war.

    Pointing to what it called Israeli “crimes” in Lebanon that violated US commitments to a ceasefire, the IRGC warned ships would be at risk if they approached the Strait, a vital conduit for global oil and gas supplies.

    But US Central Command said 55 merchant ships transited the strait on Saturday with more than 17 million barrels of oil for global markets.

    Trump said no toll will be charged for passage through the strait during or after the 60-day ceasefire – unless the US imposes one should peace talks fail. In a social media post, he cited the possibility of a toll levied by the US “for services rendered as the Guardian Angel to the countries of the Middle East” if a peace deal is not completed.

    Mohammad Mokhber, an adviser to Iranian Supreme Leader Ayatollah Mojtaba Khamenei, accused the US on X of failing to implement the first clause of its 14-point interim deal with Iran, which includes a ceasefire “on all fronts,” including Lebanon.

    He said that, as long as the agreement was only on paper, the flow of Middle East energy would remain halted.

    The Lebanon truce appeared fragile as Israeli forces and the Iran-backed militant group Hizbollah attacked each other.

    The Iranian delegation was led by chief negotiator Mohammad Baqer Qalibaf and included Foreign Minister Abbas Araqhchi as well as senior security, central bank and oil officials, Iranian media said.

    In addition to Vance, the US negotiating team includes envoys Steve Witkoff and Jared Kushner, Trump’s son-in-law.

    Iranian Foreign Ministry spokesperson Esmaeil Baghaei said Iran would press in Switzerland for fulfilment of commitments, citing past failures by the other side to honour agreements.

    Pakistani Prime Minister Shehbaz Sharif and the army chief, Field Marshal Syed Asim Munir, will attend this weekend’s sessions, the country’s ministry of foreign affairs said.

    Vance, in an interview with Fox News, said he was confident the ceasefire would hold, and that he had seen no evidence that the Strait of Hormuz was closed.

    Negotiators would likely have a “couple days of talks,” Vance told reporters at Joint Base Andrews in Maryland in the US. “I think we’re going to hopefully make progress on the nuclear issue, make progress on the Lebanon ceasefire issue.”

    The vice-president and second lady Usha Vance arrived at Emmen Air Base in Switzerland at 5.59 am (11.59 am in Singapore), a vice-presidential spokesperson said.

    Israel vows to defend its forces in Lebanon

    A halt to fighting in Lebanon was one of the conditions for starting US-Iranian talks on Teheran’s nuclear programme and other issues. But Lebanese Civil Defence said that 20 people had been killed by Israeli strikes in Lebanon on Saturday, hours after a truce there took effect.

    Israel said it was responding to attacks from Hizbollah, while the Iran-backed group said it would not allow Israel “freedom of movement” in Lebanon. Israel says it is not party to the Iran-US deal and will keep its forces in the Lebanese territory it occupies.

    A military statement said Israel was committed to the ceasefire but would continue to act against any threat to Israel or its forces.

    The Israeli broadcaster Channel 12 reported that the prime minister and defence minister instructed the military to hold fire in Lebanon, but that it would not withdraw from areas it had captured.

    A poll exclusively shared with Reuters and conducted by the Israeli Hebrew University found that some 92 per cent of Israelis believe Iran benefited more from the joint Israeli-US military campaign than Israel and only some 8 per cent of Israelis think Israel emerged victorious. Almost 90 per cent of Israelis said the goals of the war were not met and more than 70 per cent do not believe Netanyahu’s claims that there were major achievements.

    Lebanon’s state news agency NNA said Israeli warplanes and drones had struck locations across southern Lebanon and the Bekaa Valley on Saturday, both Hizbollah strongholds.

    An Israeli military official said Hizbollah fired more than 50 projectiles at Israeli forces in southern Lebanon overnight, and that Israel had attacked what it described as Hizbollah targets in response.

    Lebanon’s health ministry says 4,057 people have been killed in Israeli attacks since Mar 2, including medics, women and children, though it does not specify how many of the dead were combatants.
