IDF Shayetet 13 conducted a targeted operation in Khiam, uncovering a substantial Hezbollah weapons cache hidden inside a local school. The seizure included hundreds of arms, ranging from anti-tank missiles to mortars, as well as items marked with the UNHCR logo. Video footage released by the IDF shows soldiers inspecting stacked weaponry amid aid supplies, underscoring the scale and audacity of Hezbollah’s concealment efforts.

This discovery coincides with Israel’s intensified March 2026 ground incursions into southern Lebanon, aimed at disrupting Hezbollah’s estimated stockpile of 150,000 rockets and complex tunnel networks established since the 2006 war. By embedding weapons within civilian structures, Hezbollah exploits international norms and shields fighters from direct targeting, complicating Israeli operational planning. Such tactics mirror methods previously documented in Gaza, where underground and urban concealments have been used to avoid counterstrikes.

The presence of UNHCR-labeled items in the cache raises serious concerns about the manipulation of humanitarian aid for militant purposes. Observers note that such practices endanger civilians and undermine trust in aid organizations operating in conflict zones. The operation highlights the challenges faced by militaries when adversaries intentionally blur the line between civilian and military infrastructure.

Military analysts indicate that uncovering caches in schools or other public facilities requires precise intelligence and rapid, coordinated action to minimize collateral damage. The IDF’s seizure of the Khiam stockpile demonstrates both the effectiveness and risks inherent in such operations. Experts warn that future engagements may increasingly encounter similar embedding of arms in civilian settings, demanding careful tactical planning.

The operation also sends a strategic message to Hezbollah and other actors in the region. By revealing hidden arsenals, Israel aims to degrade militant capabilities while signaling the costs of exploiting civilian infrastructure. The incident reinforces the broader narrative of the 2026 Lebanon conflict, where asymmetric warfare and urban concealment tactics pose significant challenges for conventional forces.
