Iran war day 114: US, Iranian delegations in Switzerland for key talks

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.”
