High-level talks between the United States and Iran scheduled to take place in Switzerland have been postponed after renewed fighting between Israel and Hezbollah in Lebanon disrupted diplomatic efforts. Iranian officials declined to travel, insisting that Israel’s military operations in Lebanon must stop before negotiations can begin. US Vice President JD Vance also cancelled his planned visit.
The postponed talks were expected to focus on Iran’s nuclear programme and lay the groundwork for a broader peace agreement aimed at reducing tensions in the Middle East. Negotiators were also expected to discuss sanctions relief, regional security, and measures to prevent further escalation.
The decision came as Israel carried out airstrikes across southern and eastern Lebanon, while Hezbollah launched drone and missile attacks on Israeli positions. According to Lebanon’s Health Ministry, at least 21 people were killed in the latest violence, while Israel confirmed the deaths of four of its soldiers.
Iran has maintained that it will not participate in negotiations unless Israel halts its attacks in Lebanon, arguing that meaningful diplomatic progress is impossible while the conflict continues. Mediators are now working to reschedule the meeting, though no new date has been announced.
The Switzerland talks were considered a key step toward addressing Iran’s nuclear activities, restoring regional stability, and advancing a long-term peace framework. The interim agreement had already reopened the Strait of Hormuz to international shipping and led to limited economic concessions for Iran, including eased restrictions on oil exports.
However, the renewed violence in Lebanon has cast serious doubt over the future of the negotiations, raising concerns that the broader peace process could be delayed if the conflict continues to intensify.
