Who attacked first on the Lebanon front in 2023?

8 October 2023 · The northern front

On 8 October 2023, one day after Hamas murdered roughly 1,200 people in the October 7 massacre, Hezbollah opened fire on Israel from Lebanon. Israel had struck nothing in Lebanon and threatened nothing. Hezbollah’s own secretary-general, Hassan Nasrallah, called it a “support front,” a war of choice fought for another country’s cause, not Lebanon’s own. Fourteen months later Nasrallah was dead, Hezbollah’s command structure was in ruins, and Lebanon had absorbed a war its government never voted for and its Iranian-built militia started on its behalf.

Who opened the front, and on whose orders

Hezbollah is not an independent Lebanese actor choosing its own wars; it is the flagship of Iran’s regional network, built, armed and financed by Tehran’s Islamic Revolutionary Guard Corps since the early 1980s. Nasrallah answered to Iran’s Supreme Leader under his own organization’s founding charter, and the decision to open a second front on 8 October 2023 was announced within hours of the Hamas attack, before Israel had fired a shot into Lebanon. It fits a wider pattern that also drew in the Houthis of Yemen, who began launching missiles, drones and ship hijackings at Israel from November 2023, a thousand miles from any shared border, and Iraqi militias that fired at Israel and at US bases the same autumn. All three answered the same call, part of what Iran calls its “axis of resistance.”

What the war looked like, month by month

The first ten months were a war of attrition along the Blue Line, the UN-demarcated boundary from Israel’s 2000 withdrawal: near-daily rocket, drone and anti-tank fire from Hezbollah, met by Israeli strikes on launch sites and commanders. It escalated sharply on 27 July 2024, when a rocket struck a football pitch in the Druze town of Majdal Shams, on the Golan, and killed twelve children aged 10 to 16. Israel attributed the rocket to Hezbollah; Hezbollah denied firing it and claimed an Israeli interceptor was responsible, a claim Western assessments rejected. On 17 and 18 September 2024, thousands of pagers and hundreds of walkie-talkies issued to Hezbollah fighters exploded simultaneously across Lebanon and Syria, an operation widely attributed to Israel that killed several dozen people and wounded thousands more, the large majority of them Hezbollah operatives; Hezbollah told allies the two-day operation took some 1,500 of its fighters out of the war. On 27 September, Israeli airstrikes killed Nasrallah himself at Hezbollah’s underground headquarters in Beirut, along with much of its senior command. On 1 October, Israeli ground forces crossed into southern Lebanon in what the military called limited raids to clear Hezbollah’s border infrastructure; the campaign that followed killed hundreds more Hezbollah fighters, including senior field commanders, and cost Israel soldiers in village-by-village combat.

The toll on both sides

Hezbollah’s war cost Lebanon far more than it cost Israel. The Lebanese Ministry of Health, which like Gaza’s Hamas-run ministry does not separate fighters from civilians in its count, reported roughly 4,000 dead by early December 2024. Hezbollah itself has told allies the true number of its own fighters killed may run as high as 4,000, the great majority in the war’s last two months; the IDF’s own estimate is closer to 3,000. On the Israeli side, Hezbollah’s fire killed 45 civilians and 76 soldiers and reservists over fourteen months, and drove some 60,000 Israelis, by some counts as many as 96,000 at the peak, from their homes in the Galilee and the Golan for over a year, a displacement rarely described using that word. Lebanon’s own displacement ran higher still: over 100,000 by the ceasefire, and reportedly over a million Lebanese, roughly a fifth of the country’s population, at the war’s later peak.

The ceasefire, and what it actually said

On 26 November 2024 Israel and Lebanon agreed to a ceasefire that took effect the next morning, brokered by the United States and grounded in Security Council Resolution 1701 of 2006, the same resolution that had ended the 2006 Lebanon war and gone unenforced for eighteen years. Its terms required Hezbollah to withdraw its forces and weapons north of the Litani River, Israel to withdraw from Lebanese territory, and the Lebanese army, backstopped by UN peacekeepers, to become the only armed force south of the river. UN Secretary-General António Guterres welcomed the deal; his special coordinator for Lebanon warned that “neither side can afford another period of disingenuous implementation,” a warning that proved prescient.

The reopened front, and what stayed the same

The ceasefire never held cleanly. Israel kept striking Hezbollah rearmament it said breached the deal, and Hezbollah accused Israel of the same. The truce broke down fully after 28 February 2026, when a joint US-Israeli operation killed Iran’s Supreme Leader Ali Khamenei during the Israel-Iran war; days later, on 2 March, Hezbollah fired rockets and drones at Israel for the first time since the ceasefire, again in solidarity with its patron rather than over any Israeli move against Lebanon itself. Israel answered with an offensive that pushed to the Litani River by mid-March, and by mid-2026 two further ceasefire attempts, in April and June, had each foundered on Hezbollah’s refusal to disarm fully. The pattern of who restarts the fighting has not changed since 8 October 2023.

How the story gets told today

The framing that survives in most retellings treats Hezbollah’s opening rocket fire as a footnote to “the wider war,” and Israel’s response, the pagers, the strikes, the ground campaign, as the story’s substance. The tens of thousands of displaced Israelis rarely get the word “displacement,” a term reserved almost automatically for Lebanese and Gazan civilians. The pager operation gets described as a mass-casualty attack on Lebanon in general, when the devices were issued specifically to a designated terrorist army’s fighters and allies, not to the Lebanese public. And the 2026 reignition gets attributed to vague “regional escalation” rather than to Hezbollah’s own decision, a second time, to fire for Iran rather than stand down for Lebanon.
