Iran's delegation walked out of negotiations in Switzerland on June 21 following threats from Donald Trump regarding military action against Iran due to its support for Hezbollah. The talks aimed to address broader US-Iranian relations and end the ongoing conflicts in the Middle East.

Iran's state news agency reported the walkout after Trump reiterated threats on social media, but a diplomat indicated that negotiations were still ongoing. Tensions escalated as both nations exchanged hostile statements. Iran's negotiators emphasized their military readiness to respond to threats and stated their right to enrich uranium, denying any intentions of developing nuclear weapons.

US Vice President JD Vance characterized the meeting as historic, expressing hopes for a breakthrough in relations. However, ongoing violence in Lebanon, particularly between Israel and Hezbollah, was identified as a critical sticking point for negotiations.

With reported clashes persisting, Iran's foreign ministry underlined that a ceasefire in Lebanon was essential before advancing any agreements. Meanwhile, the death toll from the conflict in Lebanon exceeds 4,100, further complicating the peace process.
