The much-anticipated sixth round of nuclear negotiations between Iran and the United States, scheduled for June 15, 2025, in Muscat, Oman, has been officially cancelled, the Omani Foreign Minister Sayyid Badr bin Hamad Albusaidi announced on June 14 via his official social media account. This decision comes amid a sharp escalation in hostilities triggered by Israeli airstrikes on Iranian nuclear and military facilities, which have resulted in significant casualties and heightened regional tensions.
Despite the cancellation, Oman reaffirmed its steadfast commitment to peaceful diplomacy and dialogue as the only viable path to lasting peace and stability in the region.
Background: The Role of Oman as Mediator
Oman has long played a discreet but crucial role as a mediator in Middle Eastern diplomacy, particularly in facilitating dialogue between Iran and Western powers. The Sultanate’s capital, Muscat, has served as a neutral venue for multiple rounds of nuclear talks aimed at curbing Iran’s uranium enrichment program and preventing the development of nuclear weapons.
The talks, which began in April 2025, have faced numerous challenges, but Oman’s involvement has been widely regarded as instrumental in maintaining communication channels between the two adversaries.
Reasons Behind the Cancellation
The cancellation followed a series of unprecedented Israeli airstrikes on June 13, targeting Iranian nuclear sites and military commanders. These strikes killed several senior Iranian nuclear scientists and military leaders, significantly escalating the conflict.
Iran’s Foreign Minister Abbas Araghchi declared the continuation of talks “unjustifiable” in light of what he described as “barbarous” Israeli attacks. Iranian officials accused the United States of tacitly supporting Israel’s military operation, which Tehran sees as a violation of its sovereignty.
The Israeli strikes have also led to retaliatory missile and drone attacks by Iran against Israeli cities, further destabilizing the region and complicating diplomatic efforts.
Statements from Oman’s Foreign Minister
In his announcement, Sayyid Badr Albusaidi emphasized that “diplomacy and dialogue remain the only path to achieving lasting peace.” He reiterated Oman’s commitment to peaceful resolution and stressed the importance of adhering to diplomatic channels despite the current setbacks.
Albusaidi’s statement reflects Oman’s balanced approach, seeking to maintain dialogue with all parties while condemning violence and urging restraint.
US Response and Outlook on Future Talks
A senior U.S. administration official, speaking on condition of anonymity, confirmed the cancellation but stressed that the United States remains committed to the diplomatic process. The official expressed hope that Iran would return to the negotiating table soon, underscoring that diplomacy remains the preferred avenue over military confrontation.
US President Donald Trump, who has publicly threatened military action if diplomacy fails, had remained cautiously optimistic about reaching a deal, but recent events have cast serious doubt on the prospects.
Iran’s Position and Reaction
Iranian authorities have taken a hardline stance following the Israeli strikes. Foreign Ministry spokesman Esmaeil Baghaei criticized the simultaneous diplomatic overtures by the US as contradictory, accusing Washington of enabling what he called “racist regime” violations of Iranian sovereignty.
Iran suspended all passenger flights indefinitely for safety reasons and announced a state of heightened alert. Tehran’s leadership insists that any future negotiations must occur without external military pressure or attacks.
Impact on Regional Stability and Security
The suspension of talks comes at a time of heightened volatility in the Middle East, with fears of a wider regional conflict growing. The Israeli-Iranian confrontation threatens to draw in other regional and global powers, increasing the risk of prolonged instability.
Oman’s cancellation announcement highlights the fragility of diplomacy amid military escalations and underscores the urgent need for renewed efforts to prevent further violence.
International Reactions and Diplomatic Efforts
European leaders, including French President Emmanuel Macron, have urged Iran to return swiftly to the negotiating table, emphasizing the importance of diplomacy. Macron spoke with Iranian President Masoud Pezeshkian, encouraging restraint and dialogue.
The European Union and other international actors have expressed concern over the cancellation and called for renewed diplomatic engagement to avoid further escalation.
Diplomacy Faces Setback but Remains Essential
The cancellation of the Iran-US nuclear talks in Muscat marks a significant setback in efforts to resolve one of the most pressing security challenges in the Middle East. The recent Israeli airstrikes and Iran’s retaliatory actions have deepened mistrust and complicated the diplomatic landscape.
Nonetheless, Oman’s reaffirmation of its commitment to dialogue offers a glimmer of hope that peaceful negotiations can resume. The international community continues to advocate for diplomacy as the only sustainable path to peace, urging all parties to de-escalate tensions and return to the negotiating table.
