US-Iran peace deal news Highlights: JD Vance rushes to Switzerland for peace talks as Iran closes Strait of Hormuz

Mohammad Mokhber, an aide to Iran's Supreme Leader, warned that energy flows from the Middle East could remain disrupted if the agreement with the United States is not fully implemented.

He said Americans understand "the language of economics and cost-benefit," signaling that Iran could maintain pressure until its demands under the deal are met.

• Iran says it will close the Strait of Hormuz, citing continued Israeli military action in Lebanon and what it calls the US failure to implement the first clause of a tentative agreement aimed at ending the conflict. That clause called for an immediate halt to military operations, including in Lebanon, but fighting between Israel and Hezbollah has continued.
• The US military says it sees no evidence that Iran has actually shut the strategic waterway and has pledged to keep maritime traffic flowing.
• The developments come during a 60-day window for Washington and Tehran to negotiate a final agreement. Delegations from both countries are meeting in Switzerland, with US Vice President JD Vance expected to join envoy Steve Witkoff and Jared Kushner. Iran has also sent a senior delegation led by Parliament Speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi.
• Pakistan and Qatar are participating in the talks as mediators.
• Meanwhile, violence continues in Lebanon despite a recently announced ceasefire. Lebanese authorities reported at least 16 deaths in Israeli strikes on Saturday, while Israel said its operations were in response to attacks by Hezbollah.

Iran's IRGC-linked Tasnim News Agency said the Strait of Hormuz should remain closed until key provisions of the Iran-US memorandum of understanding are implemented.

The outlet cited conditions including the release of at least $12 billion in Iranian assets, oil sanctions waivers, and Israel's withdrawal from Lebanon. It argued that reopening the waterway before all commitments are fulfilled would be a strategic mistake and a breach of the agreement.

Iran does not control the Strait of Hormuz, US Central Command spokesperson said on Saturday

At least 20 people were killed in Israeli strikes across southern Lebanon and the Bekaa Valley on Saturday, according to Lebanon's state news agency, just a day after a ceasefire with Hezbollah took effect. Israel said the attacks were in response to more than 50 projectiles fired by Hezbollah overnight.

The Iran-backed group accused Israel of repeatedly violating the truce and warned that continued attacks would not go unanswered, while urging the US to pressure Israel to uphold the ceasefire.

Mona Khalil, a Lebanese conservationist known for protecting endangered sea turtles along the country's southern coast, has died from injuries sustained in an Israeli strike on her home earlier this month, according to local nonprofits.

Khalil founded The Orange House Project in 2000 to safeguard turtle nesting sites near Tyre and remained committed to the effort despite years of conflict.

The strike also injured her assistant. Israel has not commented on the incident.

Key mediator Pakistan says technical-level Iran-US talks on their interim deal will begin on Sunday in Switzerland

Israel's military will enforce a ceasefire in Lebanon following coordination with the United States and directives from the prime minister and defense minister, according to Channel 12. However, the report said Israeli forces will not withdraw from territories they have captured, signaling that key points of contention with Lebanon remain unresolved despite the truce.

Iran's negotiating team, led by Parliament Speaker Mohammad Bagher Ghalibaf, has departed for Switzerland ahead of technical talks with the United States set to begin on Sunday.

Foreign Minister Abbas Araghchi is part of the delegation, alongside senior officials from Iran's central bank, national security council, foreign ministry and oil ministry.

US Vice President JD Vance is also expected to attend the talks, according to CNN.

Iran said it would take "necessary measures" if the US fails to uphold its obligations under an initial agreement between the two countries.

The warning came as Iranian Foreign Minister Abbas Araghchi met Pakistan's Interior Minister Mohsin Naqvi, who urged Tehran to stay engaged in negotiations, arguing that Washington has enough leverage to curb Israeli strikes in Lebanon.

The conflict in Lebanon remains a major hurdle to reaching a final deal during the ongoing 60-day negotiation period.

Three Indian-flagged crude oil tankers carrying more than 8.6 lakh metric tonnes of cargo and 94 Indian crew members safely transited the Strait of Hormuz on Saturday and are headed to India, Union Minister Sarbananda Sonowal said.

The vessels—Desh Vaibhav, Desh Vibhor and Sanmar Herald—are expected to arrive at ports in Vadinar, Sikka and Paradip between June 24 and July 1.

Sonowal said the government is closely coordinating with relevant agencies to safeguard India's seafarers and energy supply routes.

Vance said there is no evidence that Iran has closed the Strait of Hormuz, despite Tehran's announcement. Speaking to Fox News, Vance noted that oil shipments through the waterway had returned to pre-war levels, with around 16 million barrels transiting in the previous 24 hours.

He also dismissed reports of ships being turned away, suggesting any navigation warnings could be related to regional security risks such as minefields rather than an Iranian blockade.

Pakistan and Qatar will take part as mediators in US-Iran talks scheduled for Sunday in Switzerland's Bürgenstock resort, Pakistan's Foreign Ministry said.

The technical-level discussions aim to advance understandings reached under the Islamabad Memorandum of Understanding. Both Washington and Tehran have confirmed they will send delegations, despite ongoing fighting in Lebanon threatening diplomatic progress.

US Vice President JD Vance is expected to travel to Switzerland as preparations continue for talks with Iran. US envoy Steve Witkoff and Jared Kushner are already in the country working on technical aspects of the negotiations. Vance said discussions could begin once Iranian, Qatari and Pakistani officials arrive, potentially as soon as Sunday, though he noted that schedules remain fluid due to diplomatic coordination and ongoing regional tensions.

Iran’s Islamic Revolutionary Guard Corps (IRGC) Navy announced on Saturday that it had closed the Strait of Hormuz to all maritime traffic, warning all vessels to stay away from the waterway.

Fars News Agency quoted a military source in the IRGC Navy as saying the strategic waterway had been “completely closed” as of Saturday morning. In a subsequent statement, the IRGC Navy said the move was a response to “US breaches of commitments in implementing the ceasefire” and “Israeli attacks in Lebanon.”

The force warned all vessels against approaching the Strait of Hormuz, saying their security could be endangered if they ignored the warning.

The US military is still not seeing any Iranian military movements on the ground that reflect a potential "closing' of the Strait of Hormuz, Axios reported citing senior US defense official.

Iran’s IRGC Navy said on Saturday that it had closed the Strait of Hormuz to all maritime traffic and warned vessels to stay away from the strategic waterway. The force said the move was in response to alleged US failures to uphold ceasefire commitments and continued Israeli attacks in Lebanon, adding that ships entering the area could face security risks.

US Vice President JD Vance said Washington and Israel may differ on how to achieve shared goals regarding Iran, stressing that President Donald Trump wants to give negotiations a chance.

Vance recently criticized Israel over attacks in Lebanon and warned that Israeli leaders should be mindful of their reliance on US support. He also suggested Israel may ultimately have to accept any Iran deal negotiated by the United States, echoing remarks made by Trump in a recent interview.

US Vice President JD Vance said he expects to travel to Switzerland within days for talks with Iran, which could begin as early as Sunday.

Speaking to Fox News, Vance said envoy Steve Witkoff and Jared Kushner were already on the ground, negotiations were progressing well, and Washington was willing to give diplomacy a chance. He also expressed confidence that the ceasefire would hold and said there was no evidence Iran was closing the Strait of Hormuz.

Iran's Khatam al-Anbiya Central Headquarters on Saturday said it would close the Strait of Hormuz to vessel traffic, accusing the US of failing to uphold the first clause of an agreement to end the war.

It also cited Israel's alleged ceasefire violations and continued presence in southern Lebanon, warning that the move was only the "first step" in its response and that further measures could follow.
