An Israeli airstrike on a vehicle in southern Lebanon on Saturday killed at least three Lebanese Army soldiers, including a brigadier general, the military in Beirut said, in a sharp escalation that threatens to unravel a ceasefire brokered only days earlier. The strike, which Lebanese authorities said also left a captain and another soldier dead, occurred on the Khardali-Nabatieh road, roughly 70 kilometres south of the capital. The Lebanese Army condemned the attack as a “barbaric and aggressive raid”, while President Joseph Aoun called it a “blatant violation of Lebanon’s sovereignty and international law”. The Israel Defense Forces (IDF) confirmed it had targeted the vehicle, saying it was “moving suspiciously towards forces” in an area where gunfire had been reported, and that it had launched an investigation.

Viewed from Beirut, the strike is the most serious spillover of cross-border violence since the conditional truce was announced following talks in the United States. The ceasefire, which envisions Hezbollah ceasing attacks and withdrawing from near the border, relies on the Lebanese Army deploying to newly designated zones to assert exclusive control. Yet the killing of its own personnel underscores the army’s precarious position—neither fully trusted by Israel as a neutral actor nor able to constrain Hezbollah’s lingering presence. “The continued, deliberate, and repeated Israeli aggression only strengthens our resolve,” the army said in a statement, reflecting an embittered mood in official circles.

Israeli officials maintain the incident was a tactical response to a moving threat, not a premeditated act against the Lebanese state. The IDF cited reports that Hezbollah was preparing to attack Israeli troops from the area. The distinction, however, does little to soothe the doubts of mediators in Washington and European capitals, who had hoped the truce would create momentum toward lasting stability. Analysts note that the Lebanese government, long opposed to Hezbollah’s armed wing, now faces a credibility test: it must demonstrate its forces are in command of the south, yet is itself now a target of the very army with which it is supposed to coordinate.

The wider context of the ceasefire compounds the risk. The deal, aimed at ending Hezbollah’s rocket and drone attacks on Israel, still lacks robust enforcement mechanisms, and both sides accuse the other of violating its terms. Saturday’s death toll—at least nine people killed overall across multiple strikes, including six in the village of Saksakiyah—illustrates the fragmentation of a truce that barely took hold. With each incident, the space for diplomacy narrows, and the prospect of a full-scale resumption of hostilities looms larger. For now, the Lebanese Army’s losses serve as a sombre reminder that ceasefires in this theatre are often little more than intervals between assaults.
