Hezbollah has publicly claimed responsibility for a cross-border attack on an Israeli military base for the first time since a fragile ceasefire between Israel and Lebanon took effect in mid-April. In a statement issued on Friday afternoon, the Iran-backed group said it struck the Shraga base, the administrative headquarters of the Golani Brigade command and the deployment site of the Egoz commando unit, south of the coastal city of Nahariya with a barrage of advanced rockets. Israeli officials confirmed that several launches were detected heading towards Israeli territory; the air force intercepted some projectiles while others fell in open areas. No casualties were reported.

The attack follows two previously unreleased videos published by Hezbollah’s military media earlier this week, showing rocket strikes on May 5 targeting Israeli army positions along the border. One clip depicted a strike on a gathering of Israeli forces near the southern Lebanese village of Khallat Raj, while the other showed the shelling of a newly established Israeli site opposite the border town of Ramyeh. Both videos featured images of the slain Hezbollah leaders Hassan Nasrallah and Hashem Safieddine, underlining the group’s emphasis on continuity and defiance.

Viewed from Beirut, the timing of Friday’s strike is deliberate. The group framed it as retaliation for what it called Israeli violations of the ceasefire, including an attack on Beirut’s southern suburb and continued strikes against villages in southern Lebanon. By choosing a symbolic target—the headquarters of a storied infantry brigade—Hezbollah signals that its military infrastructure remains intact and that it retains the capacity to escalate despite the truce.

Analysts in London note that the attack underscores the fragility of the current arrangement. The ceasefire, already subject to mutual accusations of breaches, now faces its first major test. Israel has not yet confirmed a military response, but its air force was already on alert on Friday. From Washington, the incident complicates diplomatic efforts to stabilise the border and prevent a wider regional conflagration, particularly as Iran’s influence continues to shape events across the Levant.

Looking ahead, the risk of a cycle of retaliation is high. If Israel chooses to strike deeper inside Lebanese territory, Hezbollah may respond with larger salvos, potentially drawing in other actors. For now, the focus remains on whether the two sides can salvage the ceasefire—or if Friday’s barrage marks the beginning of a renewed escalation.
