Iran has declared that there is “no point” in continuing peace talks with the United States, accusing Washington of failing to uphold its commitments following a series of Israeli airstrikes on Beirut’s southern suburbs.

The political breakdown occurred just hours before a highly anticipated, Pakistan-mediated Middle East peace agreement was reportedly scheduled to be finalized and signed.

The escalating diplomatic crisis was triggered when the Israel Defense Forces (IDF) launched targeted missile strikes against suspected Hezbollah command centers in the Dahiyeh neighborhood of Beirut. According to Lebanese civil defense officials, the bombardment struck a residential apartment building, killing three people and wounding six others. The Israeli military defended the operation as a precise and necessary response to a ceasefire violation, asserting that Hezbollah had fired three projectiles into northern Israeli territory earlier in the day.

The timing of the military raid has cast severe doubt over an imminent memorandum of understanding aimed at ending the regional war and reopening the blockaded Strait of Hormuz. U.S. President Donald Trump had confidently announced that the comprehensive accord was slated for an electronic signing on Sunday, a timeline backed by key international mediators, including Pakistani Prime Minister Shehbaz Sharif. However, Tehran has consistently maintained that any permanent settlement with Washington must guarantee a complete cessation of hostilities in both Iran and Lebanon.

Reacting sharply to the Beirut operation, Iran’s chief negotiator, Mohammad Bagher Ghalibaf, publicly questioned the diplomatic credibility of the United States. Ghalibaf argued that the fresh aggression demonstrates that Washington either completely lacks the political will to enforce regional security commitments or lacks the administrative capability to restrain its primary ally, making further negotiation loops futile.

The targeted strikes have also re-ignited domestic friction within Iran, where hardline groups have been holding nightly protest rallies in cities like Tehran and Mashhad, condemning the diplomatic engagement and accusing Foreign Minister Abbas Araghchi of compromising national strength. Following Ghalibaf’s remarks, military officials from Iran’s Khatam al-Anbiya central headquarters warned that the deadly strikes on the Lebanese capital would not go unanswered, heavily complicating back-channel messages previously being routed through Qatari mediators and increasing the immediate risk of a wider regional escalation.
