Lebanon to top the agenda as US and Iran to hold talks in Switzerland’s Burgenstock mediated by Qatar and Pakistan.

United States Vice President JD Vance has arrived in Switzerland for talks with Iran days after they signed a memorandum of understanding (MoU) aimed at ending the US-Israel war on Iran, which had sent oil prices soaring above $100 per barrel and rattled international markets.

The latest round of talks mediated by Pakistan and Qatar is scheduled on Sunday as Israel has intensified attacks on Lebanon, killing dozens of people on Saturday.

Iran’s Islamic Revolutionary Guard Corps (IRGC) announced on Saturday that it was closing the Strait of Hormuz, accusing Israel of violating the ceasefire in Lebanon. The Iranian delegation, including parliament Speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi, has also arrived in Switzerland.

Here’s what we know about the conflict, which has entered its 114th day:

Diplomacy

• The US and Iran are to hold high-level talks in Switzerland’s Burgenstock on Sunday with the US delegation led by Vance. US President Donald Trump’s special envoy Steve Witkoff and his son-in-law Jared Kushner are also part of the US delegation. Before departing for the talks, Vance told reporters he hoped to make “progress on the nuclear issue” and “on the Lebanon ceasefire issue”.
• Iran’s delegation, led by Ghalibaf and Araghchi, said its main goal is to ensure all parties fully implement the interim deal to end the war.
• Esmaeil Baghaei, spokesperson for Iran’s Ministry of Foreign Affairs, said the Iranian delegation “will be pressing for implementation” of US commitments outlined in the MoU and “seeking clarity on how exactly the other side intends to carry out those commitments”.
• Pakistani Prime Minister Shehbaz Sharif and military chief Field Marshal Asim Munir have left for Burgenstock to take part in the talks. “Pakistan will continue to support and advance the implementation of the understandings reached between the Islamic Republic of Iran and the United States,” the Pakistani Ministry of Foreign Affairs said in a statement posted on X.
• Qatari Prime Minister Sheikh Mohammed bin Abdulrahman bin Jassim Al Thani is also expected to take part in the key talks as Israel’s Lebanon attacks threaten to unravel the deal signed electronically by Trump and his Iranian counterpart, Masoud Pezeshkian, on Thursday.
• Egypt will host a four-way meeting with the foreign ministers of Saudi Arabia, Turkiye and Pakistan amid the Iran-US talks. The group first met in Riyadh on March 18, followed by meetings in Islamabad on March 29 and Antalya on April 18, reflecting growing efforts by regional powers to address crises through regional diplomacy rather than external intervention.

In Iran

• Mohammad Mokhbar, adviser and assistant to Iranian Supreme Leader Mojtaba Khamenei, warned that Tehran will not accept a paper agreement unless Washington fully implements its commitments. In a post on X, Mokhbar said the US understood pressure in economic terms. “Americans understand the language of economics and cost-benefit better,” he wrote. “When the agreement remains just on paper, the flow of Middle East energy will also come to a halt.”

• Al Jazeera’s Mohammed Vall, reporting from Tehran, said the delegation from Tehran is going to drive home the idea that Iran is not going to move forward in the implementation of the MoU unless the Israelis abide by the agreement. “They say the Americans bear the responsibility for that and that the Americans have to guarantee that the Israelis comply,” he said.
• Iran’s ⁠oil ⁠industry will be a key testing ground ⁠for any final peace agreement ⁠with the US if Western parties remain committed to its ‌spirit, Oil Minister Mohsen Paknejad says. The ministry’s Shana news agency quoted Paknejad as ⁠saying that in a ⁠post-agreement era, Iran’s oil sector would offer the global ⁠economy significant investment ⁠opportunities and ⁠has hundreds of investment projects as well as technical ‌and operational partnership contracts ready to be ‌signed.
• Amir Ghalenoei, the coach of Iran’s national football team, has criticised increasingly difficult preparation conditions for the team before Sunday’s World Cup match against Belgium, saying “conditions have become even harder” than before their opening match with New Zealand. Iran have been based in Tijuana, Mexico, for the tournament and have been travelling to the US for Group G matches due to restrictions on their stay, an issue that has drawn scrutiny throughout the World Cup.

In the US

• Trump said there will be no tolls for passage through the Strait of Hormuz unless they are collected by the US. This came after the IRGC said it had closed the waterway, through which a fifth of global oil and liquefied natural gas supplies passed before the war.
• David Sacks, Trump’s technology adviser, has defended the US-Iran MoU, calling it “a tremendous achievement” and a better path than prolonged conflict. Speaking on the All-In Podcast on Saturday, Sacks dismissed calls to escalate, arguing a ground invasion of Iran would make no sense, given Iran’s size and could require as many as a million troops. He branded any such attempt a “suicide mission”.
• Members of the Democratic Party are continuing to criticise Trump over his handling of the war with Iran. Johnny Olszewski, a Democratic congressman from Maryland, said Trump’s “war of choice” was a “disaster” and argued that the agreement with Iran was already breaking down.

In Lebanon

• Five people were killed, among them a child, a woman and two elderly people, in an Israeli raid on the village of Sohmor in Lebanon’s western Bekaa Valley, according to the National News Agency (NNA), citing the Ministry of Public Health. Sunday’s report did not specify when the attack took place. Two people of Palestinian origin were killed in Rashidieh in southern Lebanon’s Tyre district, the NNA reported.
• The Times of Israel reported on Sunday that an Israeli soldier has been killed and 13 others wounded when a barrage of rockets and a drone struck the soldiers’ position in Kfar Tebnit in southern Lebanon.
• Israeli media reports said Prime Minister Benjamin Netanyahu has ordered invading troops to hold fire in Lebanon except for those engaged in a battle raging on the Ali al-Taher Hills near Nabatieh.
