Israel Launches New Strikes in Lebanon as Ceasefire Comes Under Pressure

On April 24, 2026, one day after President Donald Trump announced a three-week extension of the Israel-Lebanon ceasefire, the Israeli military struck what it described as Hezbollah positions in southern Lebanon [1]. The strikes came in response, the IDF said, to Hezbollah rocket fire into northern Israel — a pattern that has defined the truce since it began on April 16: both sides agree to stop fighting, and both sides keep fighting.

The ceasefire sits inside a larger, more volatile frame. The United States and Iran remain locked in a naval standoff over the Strait of Hormuz. Oil prices have spiked above $100 per barrel [2]. Over one million Lebanese — roughly 20% of the population — are displaced [3]. And the country's economy, already described by the World Bank as suffering one of the worst collapses in modern history, faces a projected GDP contraction of 12-16% for 2026 [4].

From Ceasefire to War and Back Again

The roots of the current crisis stretch back to November 27, 2024, when Israel, Lebanon, and five mediating countries signed a ceasefire agreement to end the 2024 Israel-Hezbollah war. The deal required a 60-day halt to hostilities, a phased Israeli withdrawal from southern Lebanon, and Hezbollah's withdrawal north of the Litani River. A five-country monitoring panel led by the United States was tasked with overseeing compliance, and 5,000 Lebanese Armed Forces troops were to deploy in the south [5].

That ceasefire held partially but frayed continuously. By November 2025, the Lebanese health ministry and the United Nations reported that more than 330 people — including 127 civilians — had been killed by Israeli forces since the agreement took effect, with approximately 945 more wounded [6]. UNIFIL documented more than 10,000 Israeli ceasefire violations, including 7,500 airspace incursions and 2,500 ground incidents [7]. Lebanon filed a formal UN complaint in January 2026 citing "daily ceasefire violations" by Israel [8].

Israel, for its part, cited Hezbollah's ongoing military buildup as justification for continued operations. The IDF stated that UNIFIL had "completely failed to prevent Hezbollah's ongoing military build-up within its area of operations" [7]. UNIFIL disputed this, reporting it had found no new military infrastructure from non-state actors after the November 2024 truce, though it did discover over 360 illegal weapon caches, which were referred to the Lebanese Armed Forces for disposal [7].

The situation collapsed entirely on February 28, 2026, when the United States and Israel launched an air war against Iran and assassinated Supreme Leader Ali Khamenei. Hezbollah resumed rocket strikes on Israel. By March 2, a full-scale war was underway in Lebanon [9].

Operation Eternal Darkness and Its Aftermath

The most devastating single day came on April 8, 2026. Shortly after the announcement of a ceasefire in the broader U.S.-Iran conflict, and after Hezbollah signaled a pause in attacks, Israel launched what it called its "most powerful attacks" on Lebanon — dubbed Operation Eternal Darkness [10].

The IDF deployed approximately 50 fighter jets and 160 munitions against more than 150 locations simultaneously, including targets in central Beirut, the port city of Sidon, the Beqaa Valley, and the southern city of Tyre [10][11]. The strikes hit densely populated civilian areas without prior warning [11].

Casualty figures varied by source. Al Jazeera, citing Lebanon's Civil Defence, reported at least 254 killed and 1,165 wounded [11]. UN experts put the toll at 303 dead and 1,150 wounded [12]. The Lebanese government eventually reported 357 killed [10]. Human Rights Watch documented that casualties included more than 130 children, 102 women, and 57 medical workers [13]. Six hospitals were forced to close, and nine bridges crossing the Litani River were struck [13].

The IDF claimed it hit only "terror targets," killing at least 250 Hezbollah militants [10]. Lebanon called the day "Black Wednesday" and accused Israel of carrying out a massacre [10]. UN human rights experts condemned the strikes as "unprecedented bombing" and demanded an immediate halt [12].

The Current Ceasefire: Terms and Violations

The 10-day truce announced on April 16 was brokered by the United States, with Trump pledging that Washington would help Beirut "protect itself" from Hezbollah [14]. Direct Israel-Lebanon talks began on April 10 — described by both sides as "historic" — with support from Lebanese President Joseph Aoun and Israeli Prime Minister Benjamin Netanyahu [9].

On April 23, Trump announced a three-week extension following a second round of ambassador-level negotiations at the White House, mediated by Secretary of State Marco Rubio [1][15]. The extension was intended to advance direct peace talks and prevent renewed fighting from undermining U.S.-Iran negotiations [14].

But the ceasefire has been fragile from the start. On April 21, Israel reported that Hezbollah launched rockets at an Israeli position in Rab Thalathin and sent a drone into northern Israel [1]. Israel responded by striking the rocket launcher. Hezbollah said its fire was retaliation for Israeli artillery shelling of a southern Lebanese town — each side framing its actions as defensive [1].

On April 22, an Israeli strike on a car in southern Lebanon killed two people. A second strike hit a house in the same area, killing Lebanese journalist Amal Khalil and critically wounding another journalist [1]. Khalil's death brought the total number of journalists killed by Israel in Lebanon over the preceding two months to eight, according to the Committee to Protect Journalists [1].

A senior Hezbollah official publicly declared the group would not respect the negotiated terms [14]. Yet both sides have, in practice, reduced the volume of attacks since the truce began [14].

The Civilian Toll: Counting the Dead

The discrepancy in casualty figures between Lebanese, Israeli, and international sources has been a persistent feature of this conflict. Since March 2, 2026, the Lebanese government has reported more than 2,000 people killed — including health workers and journalists — and 6,588 wounded [6]. Over one million people, approximately 20% of Lebanon's population, have been displaced [9].

The UN Office of the High Commissioner for Human Rights (OHCHR) has published figures broadly consistent with Lebanese government counts, though with differences in the breakdown between combatants and civilians [12]. The IDF has provided lower total casualty figures and higher ratios of militant-to-civilian deaths, consistent with its position that operations target Hezbollah infrastructure exclusively [10].

Human Rights Watch has noted that the destruction of bridges, hospitals, and bakeries contradicts claims of precision targeting, arguing that "even if bridges constitute valid military objectives, attacks remain subject to proportionality requirements" and that "disproportionate attacks causing excessive damage to civilians are prohibited under the laws of war" [13].

Israel's Strategic Argument: The Failure of 1701

Israel's justification for continued military action — both during and between ceasefires — rests on a core argument: UN Security Council Resolution 1701, adopted in 2006, was never enforced, and no monitoring mechanism has ever stopped Hezbollah from rearming [16].

The resolution called for Hezbollah's disarmament, a ban on arms transfers to non-state actors in Lebanon, and the deployment of UNIFIL and the Lebanese Armed Forces to ensure compliance south of the Litani River [16]. In the 18 years between 2006 and 2024, Hezbollah rebuilt its arsenal to over 150,000 rockets and missiles, establishing launch positions, tunnel networks, and command infrastructure in precisely the zones 1701 was supposed to keep demilitarized [16][17].

Israeli officials and sympathetic analysts, including at the American Enterprise Institute, argue that this history demonstrates that only direct military action — including preemptive interdiction strikes — has any deterrent effect on Hezbollah rearmament [17]. The argument holds that ceasefires without credible enforcement mechanisms function as pauses during which Hezbollah reconstitutes, making Israeli military action a rational, if legally contested, response.

This position has drawn criticism from legal scholars. A Just Security analysis argued that Israel's military campaign in Lebanon violates the necessity requirement of the right of self-defense even if one grants that Hezbollah's strikes trigger that right [18]. The distinction between preemptive self-defense and preventive war — striking against a future threat versus an imminent one — remains legally contested at the international level.

The Strait of Hormuz: A Parallel Crisis

The Lebanon ceasefire cannot be understood in isolation from the U.S.-Iran standoff in the Strait of Hormuz, through which roughly 20% of the world's oil supply normally passes.

Since the February 28 strikes on Iran, the Iranian Revolutionary Guard has blocked commercial shipping through the strait, boarded and attacked merchant vessels, and laid sea mines [19]. The United States imposed its own blockade of Iranian ports on April 13, creating what analysts call a "dual blockade" [20]. Iran has seized ships, and on April 24, Trump ordered the U.S. military to "shoot and kill" Iranian small boats in the strait [21].

WTI crude oil prices reached $114.58 per barrel in April 2026 — up 43.4% year-over-year from their levels before the crisis — before settling to roughly $91 as of the latest available data [2]. Brent crude has risen above $100 per barrel [20].

The Hormuz standoff directly affects Hezbollah's strategic position. Iran's primary overland supply route to Hezbollah — running from Iran through Iraq and Syria into Lebanon's Beqaa Valley — collapsed after the fall of Bashar al-Assad in December 2024 [22]. The new Syrian government under President Ahmad Shara has actively dismantled smuggling corridors along the 375-kilometer Syrian-Lebanese border, intercepting over a dozen arms shipments, including Iranian missiles and military drones hidden in livestock feed trucks [23].

With the land corridor severed, Iran has attempted to reconstitute supply lines via maritime channels and third-country routes through Turkey [24]. But the Strait of Hormuz blockade has further constrained Iran's ability to project power or resupply its proxies. For Tehran, the calculus is stark: authorizing Hezbollah to escalate risks provoking additional Israeli strikes while Iran's own military capacity is degraded and its maritime trade paralyzed.

International Responses: Condemnation Without Consequence

The international response has been marked by a gap between rhetoric and action.

French President Emmanuel Macron condemned Israel's April 8 strikes as "indiscriminate" and expressed "France's full solidarity" with Lebanon [25]. Foreign Minister Jean-Noël Barrot called the strikes "unacceptable" [25]. But France has not imposed sanctions, suspended arms sales, or taken other concrete measures.

The United States has played a dual role: mediating the ceasefire while maintaining its military alliance with Israel and its own war against Iran. Trump's position on whether Lebanon was even covered by the broader U.S.-Iran ceasefire shifted after a phone call with Netanyahu, raising questions about Washington's reliability as a guarantor [25].

Human Rights Watch called for the suspension of arms sales and military aid to Israel, imposition of targeted sanctions on implicated officials, and an EU suspension of the trade pillar of its Association Agreement with Israel [13]. None of these measures have been adopted.

Lebanese officials have stated that a trilateral meeting is unlikely as long as Israel occupies 6% of Lebanon's territory and continues strikes despite the ceasefire [1]. The UN has described UNIFIL's mandate, set to expire in 2027, as under strain, with the organization "working on" maintaining its presence [7].

The Economic Abyss

Lebanon entered the 2026 war already in economic freefall. The World Bank has characterized the country's collapse as worse than the Great Depression, worse than Greece, and worse than Venezuela [4].

The renewed conflict has deepened the crisis. Lebanon's GDP is projected to contract between 12% and 16% in 2026, driven by the collapse of tourism, supply chain disruptions, infrastructure damage, and reduced labor mobility [4][26]. Tourism revenue losses for 2025-2026 are estimated at $3-4 billion — a figure that is outsized relative to Lebanon's shrunken economy [26]. Tourist arrivals in the first quarter of 2026 dropped by an estimated 55-65% compared to the same period in 2024 [26].

Conflict-related damage stands at an estimated $14 billion, with reconstruction needs exceeding $11 billion [27]. International aid remains stalled due to mistrust in Lebanese political elites and broader regional instability [27]. The UN's Lebanon Response Plan for 2026 reflects the scale of the crisis, but donor commitments have lagged far behind requirements [28].

If the ceasefire formally collapses and full-scale conflict resumes, the humanitarian projections are severe. Over one million people are already displaced. The health system, with six hospitals shut down since March, is operating at reduced capacity [13]. Lebanon's capacity to absorb a new wave of violence is fundamentally different from 2006 — the country was a functioning, if flawed, state then. Today it is not.

What Comes Next

The three-week ceasefire extension buys time but does not resolve any of the underlying conflicts. Israel continues to occupy 6% of Lebanese territory. Hezbollah has declared it will not abide by the negotiated terms. Iran's supply lines to Hezbollah are disrupted but not eliminated. The Strait of Hormuz remains contested. And no diplomatic or economic consequences have been imposed on any party for ceasefire violations.

The U.S.-mediated talks in Washington represent the first direct Israeli-Lebanese negotiations in decades — a development with genuine diplomatic significance [9]. But the talks are proceeding under the weight of active hostilities, mutual distrust, and a broader regional war that neither side can fully control.

The ceasefire extension expires in mid-May. Whether it holds, extends further, or gives way to renewed full-scale conflict depends on variables that are, at present, in flux: the trajectory of U.S.-Iran negotiations, Hezbollah's internal decision-making, Israel's strategic calculations, and the willingness of international guarantors to move from statements of concern to concrete action.
