2026 Lebanon War

The 2026 Lebanon War did not begin in a vacuum. Its immediate origins lie in a broader regional confrontation involving Iran and its proxy networks, which intensified following the October 7, 2023 Hamas attacks on Israel. On October 8, 2023, Hezbollah opened a "support front" for Hamas along Israel's northern border, launching sustained rocket and drone attacks that continued intermittently for more than a year.[1] A cessation of hostilities between Israel and Lebanon was reached on November 27, 2024, but the arrangement proved unstable; it was repeatedly violated and was characterized by a Jerusalem Center for Security and Foreign Affairs analysis as a tactical pause rather than a settled resolution.[2][3]

The immediate trigger for the 2026 outbreak was a series of U.S.-Israeli military operations against Iran that began on February 28, 2026.[4] Among their consequences was the killing of Iranian Supreme Leader Ali Khamenei, an event Hezbollah publicly cited as the direct cause of its subsequent attack on Israel.[5] The organization framed its March 2 barrage as retaliation carried out "in revenge for the killing of Iran's Supreme Leader, Ali Khamenei, and in defense of Lebanon and its people against Israel's aggression."[5] The Washington Institute described Hezbollah as having attacked Israel while evidently heeding orders from Iran's Islamic Revolutionary Guard Corps, connecting the barrage to the wider Iran war.[5]

The domestic Lebanese political environment at the conflict's start was also significant. Prime Minister Nawaf Salam condemned the rocket fire as a violation of the Lebanese state's authority to decide questions of war and peace, while the government directed the Lebanese Armed Forces to arrest violators and confiscate Hezbollah's weapons.[5] A Jerusalem Center for Security and Foreign Affairs analysis described the government under President Joseph Aoun and Prime Minister Salam as the first Lebanese administration since 1983 to embrace policies explicitly requiring Hezbollah's disarmament, characterizing the group's independent military apparatus as a threat to Lebanon's stability and sovereignty.[3]

Opening Salvos: March 2, 2026

In the early morning of March 2, 2026, Hezbollah launched a large barrage of rockets and drones at northern Israel, marking the formal start of the renewed open war and the breakdown of the November 2024 cessation-of-hostilities arrangement.[5] On March 11, Hezbollah launched more than 200 rockets at northern Israel, injuring two Israelis, and Israeli leaders warned that continued attacks could expand the conflict into a full-scale war on the northern front.[2] Israel responded immediately with a broad air campaign. By March 6, the IDF claimed to have struck more than 500 Hezbollah targets throughout Lebanon and conducted 26 waves of airstrikes in Beirut's Dahiyeh district.[6] The reported target set included Hezbollah headquarters, military infrastructure, financial institutions, media outlets, weapons depots, and commanders.[6] The IDF also claimed to have killed 70 Hezbollah operatives within the first week, including intelligence commander Hussain Mouqalled and firepower-management commander Zaid Ali Jumaa.[6]

Israeli strikes in the opening phase targeted dozens of Hezbollah positions and weapons sites in southern Lebanon and around Beirut.[2] Among those reported killed in Israeli operations were Abu Ali Riyan, described as a senior commander in Hezbollah's Radwan Force responsible for operations and weapons supply in southern Lebanon, and Abu Dharr Mohammadi, described as an Iranian Revolutionary Guard Corps missile commander involved in military cooperation between Iran and Hezbollah.[2]

Displacement and Humanitarian Impact

Israel issued evacuation warnings during the first days of the war for dozens of localities in southern Lebanon and the Beqaa Valley, later ordering the evacuation of areas south of the Litani River and neighborhoods of Beirut's Dahiyeh district.[6] By March 6, ongoing combat and evacuation warnings had displaced an estimated 100,000 to 300,000 Lebanese.[6] That figure grew dramatically as the conflict deepened. By early April, the Long War Journal reported 1,345 Lebanese killed, more than 4,000 injured, and approximately 1.2 million displaced.[7] Lebanese authorities later reported that more than 1.2 million people had been displaced in total — a number exceeding displacement estimates from Lebanon's 1975–1990 civil war.[8] A Jerusalem Center for Security and Foreign Affairs analysis described severe destruction in southern Lebanon, the Beqaa Valley, and Beirut's southern suburbs, predominantly Shiite communities where Hezbollah had historically maintained an extensive social and financial network.[3]

Ground Operations and the Security Zone

Israel expanded ground operations in southern Lebanon.[7] It established a security zone extending approximately 5 to 10 kilometers from the border and covering roughly 5 percent of Lebanon's territory, intended to prevent Hezbollah from using the area to stage attacks.[8][4] Israeli forces continued clearing what they described as Hezbollah infrastructure even during ceasefire periods.[8] On September 3, 2026, the IDF announced that its 36th Division had cleared Hezbollah personnel from two underground routes beneath the Ali al-Taher Ridge in southern Lebanon and claimed "operational control" above and below ground. The Long War Journal noted that the Israeli claim remained independently unconfirmed.[9]

Hezbollah's Rocket Campaign

The Israeli military reported that Hezbollah fired approximately 5,500 rockets at Israeli troops operating in southern Lebanon and around 2,500 rockets at Israel itself during the fighting.[8] These attacks killed two Israeli civilians.[8] During the first 24 days of the ceasefire period beginning April 17, 2026, a tally attributed to the Alma Research and Education Center documented 220 Hezbollah attack waves against Israeli personnel and territory: 140 drone incidents, 58 rocket or missile attacks, and 22 incidents involving anti-aircraft fire, small arms, anti-tank weapons, or explosive devices.[10] The same report listed later drone attacks on May 12–14 that wounded two Israeli soldiers and three Israeli civilians.[10] On September 2, 2026, the IDF reported that Hezbollah launched two explosive drones at Israeli troops near the Ali al-Taher Ridge; one was intercepted, and Israel struck Hezbollah sites in the Nabatieh area in response. No injuries were reported.[11]

Hezbollah also reportedly killed a French UNIFIL peacekeeper and wounded several others during the conflict.[12] The group did not publish its own casualty figures.[8]

Casualty figures for the 2026 Lebanon War varied by source, date, and methodology, and no independent comprehensive count was established by the time of writing.

On the Lebanese side, the country's Health Ministry reported that by May 18, 2026, the death toll had reached 3,020, including 292 women and 211 children.[13] The ministry did not identify how many of those killed were combatants rather than civilians.[13] Reuters-cited sources estimated that several thousand Hezbollah fighters had also been killed, a figure Hezbollah disputed.[13] The Congressional Research Service, in its own accounting, reported more than 4,300 people killed in Lebanon during the renewed fighting, likewise without distinguishing civilians from combatants.[4] Competing estimates of Hezbollah's military losses also emerged: the IDF claimed 700 Hezbollah operatives killed as of early April, while unnamed sources familiar with Hezbollah's own count placed the group's losses at 400.[7]

By May 18, Israeli authorities reported that 20 IDF soldiers and one Defense Ministry civilian contractor had been killed in southern Lebanon.[13] Two Israeli civilians had been killed by Hezbollah rocket attacks, while one additional Israeli civilian was killed in northern Israel by Israeli artillery shelling in what was described as a mistaken-fire incident.[13] On June 19, a ceasefire flare-up near Kfar Tebnit killed four Israeli soldiers after a suspected drone or anti-tank missile struck their tank. Israel responded with 150 strikes on what it identified as Hezbollah targets, and Lebanon's Health Ministry reported at least 47 people killed and 97 wounded in the exchange, including at least seven women and two children.[14][9]

April 16 Cessation of Hostilities

A ten-day cessation of hostilities between Israel and Lebanon began on April 16, 2026, at 17:00 EST, following direct talks brokered by the United States.[15] The agreement preserved Israel's right of self-defense and halted Israeli offensive military operations against Lebanese targets, while requiring Lebanon to take meaningful steps to prevent Hezbollah and other non-state armed groups from attacking Israel.[15] The April document stated that Israel and Lebanon regarded themselves as not at war and would pursue direct negotiations toward a comprehensive peace and security agreement.[15] It further affirmed that Lebanon's official security forces were to have exclusive responsibility for Lebanese sovereignty and national defense, and that negotiations would address remaining issues, including demarcation of the international land boundary.[15]

The April ceasefire did not require Israel to withdraw from Lebanese territory, allowing Israel to maintain a buffer zone along the border.[12] Israel carried out self-defense strikes against Hezbollah operatives after the ceasefire was announced, following the deaths of two IDF soldiers in explosive attacks.[12] A diplomat working on Lebanon described the ceasefire text as a "detailed recipe for internal confrontation," underscoring the fragility of an arrangement between Israel and Lebanon's government but not Hezbollah, which was not a signatory.[8][10]

May Extension and Further Talks

On May 14–15, the United States facilitated a second round of talks between Israel and Lebanon. The parties agreed to a 45-day extension of the April 16 cessation of hostilities and planned separate political and security tracks, including a security track involving military delegations from both sides.[16] These negotiations proceeded alongside continuing tactical friction, including attacks that the State Department attributed to Hezbollah.[16]

Israeli President Isaac Herzog stated on June 21, 2026, that Hezbollah had violated the ceasefire declared by President Trump, firing on 50 sites in the preceding days, and said that Iran's involvement through Hezbollah undermined the Lebanese leadership's ability to make peace.[17] Herzog characterized Israeli and Lebanese intentions as mutually peaceful but described Hezbollah and its Iranian patron as the principal obstacles.[17]

June 26 Trilateral Framework Agreement

The most consequential diplomatic development of the conflict came on June 26, 2026, when Israel, Lebanon, and the United States adopted a Trilateral Framework Agreement in Washington, D.C.[18] The framework declared an intention to end the conflict, formally conclude any state of war, preserve the sovereignty and security of both countries, and establish peaceful, neighborly relations through continued direct negotiations.[18]

Under the framework, Lebanon committed to restore full sovereignty and the state's monopoly on the use of force, completely and verifiably disarm all non-state armed groups, and ensure that such groups retained no military or security role or armed capabilities anywhere in Lebanon.[18] The Lebanese Armed Forces were to assume full military and security control with international and Arab support led by the United States.[18]

The agreement established a reciprocal and sequenced process: after non-state armed groups were disarmed and their associated infrastructure dismantled — and after those steps were verified — the IDF would progressively redeploy from Lebanese territory.[18] Two initial pilot zones, agreed upon by the IDF and the Lebanese Armed Forces, were designated as the first test of this mechanism, though their specific locations were not given in the published framework.[18] After verified disarmament in a pilot zone, the Lebanese Armed Forces would assume security responsibility, internationally supported reconstruction could begin, and civilians could return under Lebanese state control.[18]

Israel declared explicitly in the framework that it had no territorial ambitions in Lebanon, linking the end of any future Israeli military presence to the disarmament and dismantlement of non-state armed groups throughout Lebanon and to additional security arrangements agreed by both countries.[18] Israeli President Herzog described the agreement as a major breakthrough and a possible cornerstone for peace, stating that it required the removal of Hezbollah and could enable a true peace agreement.[19]

On July 21, 2026, the IDF began withdrawing from three villages in southern Lebanon in preparation for the Lebanese military to assume control — the first experiment with the pilot zones mandated by the June framework.[20] The Lebanese military was not expected to remove Hezbollah from those villages, but rather to prevent Hezbollah from returning after the IDF had cleared them.[20]

Ongoing Negotiations Through August and September

U.S.-mediated Israel-Lebanon talks resumed in Rome in August after earlier rounds in Washington and Rome.[21] U.S. Ambassador to Lebanon Michel Issa warned that substantial technical work remained to implement the June framework safely, encompassing pilot-zone logistics, border disputes, civilian-protection protocols, and the path to a comprehensive peace agreement.[21] During this period, Lebanese Armed Forces personnel were injured near Bint Jbeil in an explosion that was initially attributed to an Israeli attack. A subsequent investigation determined that their vehicle had detonated a Hezbollah explosive device outside the southern Lebanon security zone, while the Lebanese Army later described the cause as a "suspicious object" under investigation.[21]

As of early September 2026, the Congressional Research Service described the conflict as continuing: Hezbollah had resumed attacks, Israeli ground operations had expanded, Israel maintained its southern buffer zone, and the June framework had not been fully implemented.[4] The report identified unresolved questions concerning Hezbollah's disarmament, Israeli withdrawal, Lebanese Armed Forces deployment, and the ability of Lebanese authorities to compel Hezbollah to comply.[4]

The June 26 Trilateral Framework Agreement faced immediate internal resistance within Lebanon. Hezbollah rejected the agreement within minutes of its signing; Hezbollah parliamentarian Hassan Fadlallah stated that the organization would oppose implementation and hold more firmly to its weapons.[22] A Jerusalem Center for Security and Foreign Affairs analysis argued that the Lebanese Armed Forces lacked both the military capability and the political capital to impose disarmament without risking national collapse, internal violence, or renewed civil conflict.[22]

The Lebanese government formally banned Hezbollah's military activities after the group resumed firing into Israel, a measure the Congressional Research Service described as unprecedented but largely symbolic, since Hezbollah continued to refuse disarmament despite demands from both the Lebanese government and the United States.[4] Observers working on Lebanon described the ceasefire and framework texts as potential sources of internal confrontation given the gap between the Lebanese state's formal commitments and Hezbollah's defiant posture.[8]

The war intensified longstanding tensions between Hezbollah and Lebanon's domestic opponents, evoking comparisons to the dynamics of Lebanon's civil-war era.[8] Prime Minister Salam condemned Hezbollah's rocket fire as a violation of the state's authority over war and peace, while the government directed the Lebanese Armed Forces to confiscate the group's weapons.[5] A Jerusalem Center for Security and Foreign Affairs analysis described the Salam-Aoun government as the first Lebanese administration since 1983 to embrace policies explicitly requiring Hezbollah's disarmament.[3]

Parallel to military and diplomatic efforts, financial and legal pressure on Hezbollah also intensified. A Jerusalem Center for Security and Foreign Affairs analysis reported that in June 2026, Lebanon's Ministry of Justice opened an investigation into Al-Qard al-Hassan, described as Hezbollah's de facto central bank, to determine whether it exceeded its legal mandate as a non-governmental organization and violated Lebanese financial law.[3] The same analysis described U.S. Treasury sanctions against Hezbollah financial facilitators and organizations associated with its financial infrastructure as part of a broader effort to weaken the group's ability to finance reconstruction, compensate affected families, and sustain its social-welfare network.[3]

A Tel Aviv University Peace Index survey conducted on March 23–28, 2026, with 607 Israeli adult respondents — 504 Jewish and 103 Arab — captured Israeli attitudes during the fighting.[23] The survey found that 59 percent of the full sample supported a ground incursion aimed at disarming Hezbollah, with support reaching 67 percent among Jewish respondents and 24 percent among Arab respondents.[23]

Diplomacy, however, drew even stronger support. Some 67 percent of the full sample supported direct negotiations with the Lebanese government to end the war and disarm Hezbollah, while 71 percent supported negotiations with the Lebanese government toward a peace agreement as part of the Abraham Accords.[23] Among Jewish respondents, support for the two diplomatic tracks stood at 69 and 73 percent, respectively; among Arab respondents, at 56 and 59 percent.[23] The survey characterized its results as indicating that Israeli respondents did not necessarily view military and diplomatic tracks concerning Hezbollah's disarmament as mutually exclusive.[23]

Breaking down opinion by political camp, support for a ground incursion reached approximately 80 percent among both right-wing and moderate-right Jewish respondents, 68 percent among centrists, and 49 percent among left-wing respondents.[23] Support for direct negotiations with the Lebanese government to end the war ranged from 58 percent on the right to 93 percent on the left, while support for negotiations toward a peace agreement ranged from 70 percent on the right to 95 percent on the left.[23] Among coalition voters, 72 percent supported a ground incursion, 60 percent supported direct negotiations to end the war, and 67 percent supported negotiations toward a peace agreement.[23]

By July 2026, the Tel Aviv University Peace Index reported that Israeli public debates had shifted toward implementation of the agreements ending the fighting in Gaza and Lebanon, with ongoing discussions and tensions over the Lebanon framework agreement reflecting the unresolved nature of the situation on the ground.[24]

As of September 2026, the 2026 Lebanon War remained an unresolved conflict rather than a concluded one. The June 26 Trilateral Framework established a diplomatic architecture for a permanent peace, but its core requirements — the complete, verified disarmament of Hezbollah and other non-state armed groups, the dismantlement of associated infrastructure, and the Lebanese Armed Forces' assumption of full security control — had not been met.[4] Israeli forces continued to hold the southern security zone and conduct operations against what they identified as Hezbollah threats, while Hezbollah continued to launch drones and rockets at Israeli personnel in the zone.[11][9]

The humanitarian consequences of the conflict were severe and enduring. More than 1.2 million people were displaced in Lebanon, and the Lebanese Health Ministry counted more than 3,000 dead by mid-May, with the Congressional Research Service placing the toll above 4,300.[4][13] A Jerusalem Center for Security and Foreign Affairs analysis described Hezbollah's ability to finance reconstruction, compensate affected families, and sustain its social-welfare network as severely weakened by the conflict.[3]

The framework's pilot-zone mechanism, first tested in July 2026 when the IDF began withdrawing from three villages in anticipation of Lebanese Armed Forces deployment, represented a model for incremental implementation — but its durability depended on Hezbollah's compliance, which the group had publicly refused.[20][22] U.S. Ambassador Issa's warnings in August about the volume of remaining technical work underscored that the gap between the framework's written commitments and operational reality remained large.[21]

A Jerusalem Center for Security and Foreign Affairs analysis argued that the Salam-Aoun government's formal alignment with a disarmament agenda offered Lebanon an opportunity to restore state sovereignty over its territory and its monopoly on the use of force.[3] Whether the Lebanese state possessed the institutional capacity to do so without triggering internal conflict remained the central unresolved question of the post-framework period.[22]

Multiple aspects of the 2026 Lebanon War were contested by the parties and among analysts. Casualty figures varied significantly by source, date, and methodology: the Lebanese Health Ministry's totals did not distinguish civilians from combatants, the Congressional Research Service reported more than 4,300 killed without specifying a breakdown, and Israeli and Reuters-cited estimates provided separate figures for Hezbollah military losses that Hezbollah itself disputed.[13][4][7] No independent, comprehensive casualty count had been established as of the time of reporting.

The characterization of the conflict's cause was also disputed. Hezbollah described its March 2 attack as retaliation and self-defense; the Washington Institute described it as an attack connected to a wider Iranian-directed regional confrontation.[5] The legal and political status of the various ceasefires was similarly contested: the April document stated that Israel and Lebanon were not at war, while the Congressional Research Service and security analysts described renewed or continuing hostilities between Israel and Hezbollah.[4][15]

Claims concerning the number of Hezbollah targets struck, the scale of Hezbollah military losses, and the precise scope of Israeli operations were generally attributed to the IDF or allied sources and were not independently verified. The Long War Journal, for example, reported that Israel's claim of operational control over the Ali al-Taher Ridge remained independently unconfirmed.[9] The July pilot-zone implementation and the extent to which the June framework was being translated into operational reality were described differently by different sources, with the Jerusalem Center for Security and Foreign Affairs warning that the framework might remain a diplomatic blueprint rather than an operational reality.[22][20]
