Israeli Strikes on Beirut Threaten U.S.-Iran Peace Deal Hours Before Expected Signing

Just hours before the United States and Iran were expected to sign a landmark agreement to end their four-month war, Israeli airstrikes on Beirut's southern suburbs have threatened to derail the fragile peace process.[1][2]

On Sunday morning, the Israeli military launched targeted strikes against Hezbollah infrastructure in the Dahiyeh district of the Lebanese capital. The Israel Defense Forces stated the operation was a direct retaliation for three projectiles fired by Hezbollah into northern Israel earlier in the day.[2][5]

Smoke was seen rising over the densely populated area, marking the most severe escalation between Israel and Iran-backed forces since a tenuous ceasefire took hold on April 7. The office of Israeli Prime Minister Benjamin Netanyahu issued a statement emphasizing that Israel would not tolerate firing into its territory, regardless of broader regional diplomacy.[1][2]

The strikes landed at an extraordinarily sensitive moment. Mediated by Pakistan, the U.S. and Iran have spent weeks hammering out a memorandum of understanding to formally end the conflict that began in late February.[5][6]

U.S. President Donald Trump had publicly announced that the deal was scheduled to be signed on Sunday, promising the immediate reopening of the Strait of Hormuz—a vital global oil artery that has been virtually shut down by the hostilities. Pakistani Prime Minister Shehbaz Sharif echoed the optimism, stating the two sides were closer to peace than ever before and preparing for an electronic signing.[2][4][6]

However, the Beirut strikes immediately threw the diplomatic timeline into chaos. Iranian officials reacted furiously, warning that the attack on their Lebanese ally could scuttle the agreement entirely.[1][3]

Iran's Parliament Speaker Mohammad Bagher Qalibaf stated that the strikes prove the United States either lacks the will to fulfill its commitments or the ability to control its allies. A senior Iranian military official went further, vowing that the attack on Beirut would not go "unanswered."[2][3]

Following the strikes, Iran's Foreign Ministry spokesperson Esmaeil Baghaei denied that any signing would take place on Sunday, though he left the door open for an agreement in the coming days.[4][6]

The friction highlights a core vulnerability in the peace process: Israel has been largely sidelined from the U.S.-Iran negotiations. The Israeli government views the emerging deal with deep skepticism, particularly regarding its provisions on Iran's nuclear program.[2][4][7]

According to U.S. officials, the proposed agreement would extend the current ceasefire by 60 days. During this window, technical discussions would commence on dismantling Iran's highly enriched uranium stockpile, which the U.S. and Israel targeted during the opening days of the war.[4][6]

In exchange for nuclear concessions and the reopening of the Strait of Hormuz, Iran would receive phased relief from U.S. sanctions and access to billions of dollars in frozen assets.[5][6]

Trump has reportedly pressed Netanyahu to hold off on major military actions while the deal is finalized, hoping to secure a definitive diplomatic victory. Yet Sunday's events underscore the difficulty of decoupling the U.S.-Iran track from the ongoing border conflict between Israel and Hezbollah.[2][3][7]

The world now watches to see if the diplomatic framework can survive the weekend's violence. Qatari and Pakistani mediators are scrambling to keep both sides at the table, knowing that a collapse in talks could plunge the region back into full-scale war and send global energy markets into a tailspin.[1][5]
