Lebanon on Tuesday formally expelled Iran’s ambassador-designate and declared him persona non grata, a sovereign assertion without precedent in modern Lebanese diplomacy and one that signals the accelerating disintegration of Tehran’s grip on a nation its proxies have dominated for four decades. The Lebanese Foreign Ministry announced that it had withdrawn accreditation from Ambassador-designate Mohammad Reza Sheibani and ordered him to leave Lebanese territory no later than Sunday, March 29, according to Al Jazeera, Al-Monitor, and The National. The decision was communicated to Iran’s chargé d’affaires in Beirut, Tawfiq Samadi Khoshkho, who was summoned to the ministry by Secretary-General Abdul Sattar Issa, Al-Monitor reported.
Lebanese Foreign Minister Youssef Raggi, a career diplomat appointed in February 2025 under President Joseph Aoun’s government, personally directed the action. Writing on the social media platform X, Raggi stated that he had instructed the ministry to summon the Iranian chargé d’affaires and inform him of Beirut’s decision to revoke the agrément for Sheibani and declare him persona non grata, according to the Times of Israel and the Washington Examiner. Sheibani had been appointed to the post only in February 2026 as a replacement for Mojtaba Amani, who was seriously injured in the September 2024 pager attack, the Washington Examiner reported. The Jerusalem Post noted that Sheibani had not yet presented his credentials, though he had previously served in the same role during the 2006 war.
In parallel, Beirut recalled its own ambassador to Tehran, Ahmad Sweidan, for consultations, citing what the ministry described as Tehran’s violation of diplomatic norms and established practices between the two countries, according to TRT World and The National. The recall represents a comprehensive diplomatic downgrade — the most forceful expression of Lebanese state authority against Iranian interference since the Islamic Republic first established its network of influence in the country through the creation of Hezbollah in 1982.
The expulsion is the latest in a cascade of Lebanese government actions aimed at severing the institutional ligaments binding Tehran to Lebanese territory. On March 5, the Lebanese cabinet voted to reimpose visa requirements on all Iranian nationals entering the country, ending the previous visa-free arrangement, according to Al Arabiya. Information Minister Paul Morcos announced that the government had simultaneously ordered security forces to identify, detain, and deport any members of Iran’s Islamic Revolutionary Guard Corps found on Lebanese soil, the Middle East Monitor reported. These measures were taken after Beirut accused the IRGC of commanding Hezbollah’s operations in its war against Israel, according to The New Arab.
The diplomatic rupture traces its origins to the catastrophic sequence of events that began on February 28, when joint American and Israeli strikes under Operations Roaring Lion and Epic Fury killed Iranian Supreme Leader Ayatollah Ali Khamenei in Tehran, according to NPR and the Jerusalem Post. In response, Hezbollah — the Iranian-backed Lebanese armed group — launched rocket and drone attacks against a military base in Haifa, northern Israel, on March 2, the first such strikes since the November 2024 ceasefire agreement, Al Jazeera reported. Hezbollah declared the attack was in retaliation for the killing of Khamenei, according to the Jewish News Syndicate.
The Lebanese government banned Hezbollah’s military activities on March 2, Al Jazeera reported, but the armed group defied the order and continued its attacks. The government of Prime Minister Nawaf Salam has accused Hezbollah of dragging Lebanon into a war without the consent of the Lebanese state, according to Asharq Al-Awsat. The frustration is more than rhetorical: Lebanon’s population, still recovering from the devastation of the 2024 war, now faces a renewed Israeli military campaign of punishing scale.
The human cost has been staggering. According to Al Jazeera’s live tracker citing Lebanon’s Health Ministry, at least 1,039 people have been killed in Israeli attacks on Lebanon since the escalation began on March 2, including at least 118 children. At least 2,876 people have been wounded. Human Rights Watch reported on March 23 that the dead included 40 medical workers. More than one million people have been displaced, according to Al Jazeera, as Israel has issued sweeping forced evacuation orders covering all of southern Lebanon below the Litani River and Beirut’s southern suburbs.
Israel’s military response to Hezbollah’s reentry into combat has been expansive and unrelenting. Israeli jets struck Beirut’s southern suburbs at least seven times overnight into Tuesday, The National reported, renewing attacks on the Lebanese capital after a two-day pause. Israeli Defense Minister Israel Katz declared on Tuesday that the military would control territory up to the Litani River, creating a defensive buffer zone, according to The New Arab. Katz stated that the hundreds of thousands of displaced residents of southern Lebanon would not be permitted to return until Israeli security was guaranteed — a posture that the Times of Israel reported reflected Israel’s determination to dismantle Hezbollah’s military capacity once and for all.
The strategic calculus behind Beirut’s decision to expel Sheibani extends beyond the immediate crisis. The Jerusalem Post reported that the decision followed a week of meetings between Lebanese officials and regional counterparts, many of whom have themselves been struck by Iranian missile and drone attacks in the wider conflict. Last week, Lebanon’s foreign ministry expressed solidarity with Kuwait and the United Arab Emirates following the discovery of Hezbollah cells operating in those countries. The Washington Examiner characterized the expulsion as a move that would have been unthinkable as recently as two years ago, when Hezbollah’s political dominance made any confrontation with Tehran a political impossibility.
For the United States, the fracturing of Iranian influence in Lebanon represents a strategic development of the first order. Washington has invested decades of diplomatic capital and billions in military aid toward the goal of a sovereign Lebanese state free from Iranian domination. The November 2024 ceasefire agreement, brokered with American mediation, required Hezbollah to disarm — a demand the group refused to honor even as Israel continued operations on Lebanese territory. Hezbollah’s decision to violate that ceasefire and reenter hostilities alongside Tehran has, paradoxically, created the political conditions under which the Lebanese government could act against Iranian influence with a degree of public support that would have been inconceivable before the group’s reckless adventurism.
Israel Hayom reported that the deployment of IRGC officers on Lebanese soil was among the specific provocations that pushed Beirut to act. The Lebanese government’s characterization of the Iranian embassy as a de facto IRGC operations hub — an assessment long shared by American and Israeli intelligence — has now been given formal diplomatic expression through the expulsion. The Alma Research and Education Center’s Sarit Zehavi told the Jerusalem Post that the move was significant because the Iranian embassy had historically served as a conduit through which the IRGC directed Hezbollah’s activities.
The question that now confronts Lebanon is whether the diplomatic gesture can be matched by enforcement on the ground. Hezbollah continues to fire an average of approximately 150 rockets per day into Israel, according to Human Rights Watch citing the Israeli military. The Lebanese Armed Forces, hobbled by years of underfunding and political paralysis, are attempting to extend state authority across contested territory even as the Israeli military conducts ground operations in the south and airstrikes across the country. Foreign Minister Raggi himself acknowledged the difficulty of the task, telling the Washington Institute earlier this year that the LAF cannot simultaneously disarm Hezbollah south and north of the Litani River.
As of Tuesday evening, Sheibani had five days to depart Lebanese territory. Tehran had not yet issued a formal response to the expulsion. The broader war between the United States, Israel, and Iran — now in its twenty-fourth day — continued without interruption, with explosions reported across Iran, Israel, and several Middle Eastern states, according to Al Jazeera’s tracker. Whether Lebanon’s assertion of sovereignty against its most powerful patron endures or collapses under the weight of Hezbollah’s armed defiance will be determined not by diplomatic communiqués but by the capacity of the Lebanese state to enforce its own writ on its own soil — a capacity that remains, at this hour, very much in doubt.
