**Deck**: Israeli officials say they destroyed a massive Hezbollah tunnel in southern Lebanon that they had not previously identified, while Lebanese sources report an explosion so large it split the village of Majdal Zoun in two. The piece explains what the newly revealed tunnel complex, ongoing demolitions, and claims of Hezbollah fighters trapped underground mean for civilians, for Lebanon’s army, and for the next phase of the Israel–Hezbollah confrontation.

The war between Israel and Hezbollah is moving further underground—with consequences that are now tearing through the surface of southern Lebanon’s villages.

Lebanese sources report that a powerful explosion in the village of Majdal Zoun in southern Lebanon, carried out by the Israel Defense Forces to destroy what Israel says was Hezbollah infrastructure, has opened a chasm splitting the village into two parts. Images from before and after the blast show a visibly scarred landscape. Israeli officials have separately stated that they recently uncovered and demolished an enormous tunnel in Lebanon that was previously unknown to them, describing it as unlike anything they had seen before.

In public briefings, Israel’s defense minister said the tunnel was part of Hezbollah’s deep underground network and acknowledged that it had not been detected prior to its destruction. Another briefing framed the operation as part of a broader campaign targeting subterranean complexes, including a site at Ali al‑Taher in southern Lebanon where Israel claims to have surrounded a Hezbollah underground facility with “thousands” of soldiers and trapped dozens of fighters below ground. These claims cannot be independently corroborated, but they underscore an Israeli narrative that the current fighting is as much about the unseen layers beneath villages and hills as it is about rocket exchanges above ground.

For residents of places like Majdal Zoun and Deir Mimas–Beaufort, where Lebanese media report controlled demolitions by the IDF, the human cost is immediate. Buildings destroyed or destabilized by blasts, unexploded ordnance, and gashes in roads and farmland complicate daily life and raise the cost of eventual reconstruction. When a village is physically divided by a crater, access to schools, clinics, and family networks can be cut overnight. Even when demolitions are described as “controlled,” they occur in areas where people still live, farm, and attempt to navigate a front line that shifts by the week.

From Israel’s perspective, the operations highlight both risk and opportunity. Discovering a tunnel that officials say they did not previously know about points to gaps in intelligence and detection capabilities against Hezbollah’s decades‑old investment in underground infrastructure. At the same time, successfully collapsing such tunnels allows Israel to claim progress against what it sees as strategic assets designed for storing rockets, moving fighters, and staging cross‑border raids. The reference to tunnels “the likes of which have not been seen” is intended to signal both the scale of the threat and the determination to meet it.

Strategically, the focus on tunnels intersects with Israel’s wider messaging about its presence in Lebanon. The defense minister has told U.S. Central Command’s chief that Israel will not withdraw from security zones in Lebanon until Hezbollah is disarmed, and has criticized past U.S. decisions for allegedly preventing a more decisive blow against the group. By tying tunnel discoveries to a pledge of an open‑ended security footprint, Israeli leaders are linking tactical battlefield finds to long‑term political objectives.

For Lebanon’s army and political leadership, the dynamic is constraining. Israeli officials now say that Hezbollah’s presence in border villages is so extensive that it is effectively acting “instead of the Lebanese army,” a claim that, if accurate, undercuts Beirut’s argument that its national institutions represent the state throughout the south. The more tunnels and underground complexes are exposed under civilian areas, the harder it becomes for Lebanese authorities to argue that the country is simply a passive victim of external aggression.

The insight is blunt: when a single demolition can carve a Lebanese village in two, underground strategy is no longer invisible—it redraws the map that civilians live on.

Signals to watch include whether Israel releases detailed imagery or maps of the destroyed tunnels, how Hezbollah responds in its own messaging and operations, and whether external mediators can secure arrangements that limit heavy demolitions in populated areas. Any escalation around sites like Ali al‑Taher, or evidence of further large‑scale underground complexes, would show that this subterranean war is still in its early stages.
