The Israeli military announced on Saturday that it had struck more than 85 infrastructure sites belonging to Hezbollah over the preceding day, in a wave of air and ground attacks that targeted weapon storage facilities, launchers and an underground production facility in the Beqaa Valley. The operation marked the most intensive Israeli action since the ceasefire with the Lebanese militia took effect on 17 April, and came after a series of escalatory exchanges that have steadily eroded the fragile truce. Viewed from Tel Aviv, the strikes were framed as a direct response to rocket fire directed at Israeli soldiers in southern Lebanon, but analysts in the region note that the scale of the bombardment — the largest single-day tally since the truce — signals a deliberate recalibration of Israeli deterrence strategy.

Hours earlier, air-raid sirens had sounded across northern Israel from the Lebanese border to the outskirts of Haifa for the first time since the ceasefire began, following a volley of projectiles launched from Lebanon. The Israeli military said its air force intercepted one projectile and the remainder fell in open ground without causing casualties. The activation of sirens so deep inside Israeli territory, however, underscored the precarious nature of the truce and the ability of Hezbollah to reach beyond the immediate border area. In Beirut, where the fragilities of the Lebanese state compound the challenges of containing the militia, the incident was interpreted as a reminder that Hezbollah retains both the will and the means to disrupt calm.

The precariousness of the situation was further underscored by two separate Hezbollah drone attacks that wounded three Israeli soldiers on Friday, one of them seriously. In the first incident, an explosive drone detonated in Israeli territory near the border with Lebanon, severely wounding one soldier and moderately injuring another. In the second, several drones struck near Israeli forces operating inside southern Lebanon, leaving one soldier moderately wounded. The Israeli military confirmed the casualties and evacuated the wounded to hospitals. These attacks followed the killing of a senior Hezbollah commander, Ahmad Ghaleb Balout, the head of the Radwan special forces unit, in an Israeli airstrike in Beirut on Thursday — the highest-ranking Hezbollah figure eliminated since the ceasefire.

From London and Washington, the trajectory of events is being watched with deepening concern. The simultaneous intensification of Israeli strikes and Hezbollah’s capacity to inflict casualties suggests that the mechanisms underpinning the truce — including UNIFIL patrols and Lebanese army deployments — are proving insufficient to contain escalation. Analysts point to a logic of mutual deterrence fraying on both sides: Israel appears unwilling to tolerate even limited rocket fire without a disproportionate response, while Hezbollah views the killings of its commanders as a breach that demands retaliation. Whether the two sides accept a return to the terms of the ceasefire, or whether the coming days will see a broader confrontation, now depends on the calculations of leaders in Tel Aviv, Beirut and Tehran. What is clear is that the period of relative quiet has ended, and the border once again resembles a tinderbox.
