The Israeli military announced on Thursday, September 10, 2026, that it has completely destroyed a multi-kilometer Hezbollah underground complex situated on the Ali al-Taher ridge in southern Lebanon. In a joint statement released in Jerusalem, Israeli Prime Minister Benjamin Netanyahu and Defence Minister Israel Katz confirmed that Israeli forces established total operational control over the highland both above and below ground before detonating the subterranean facility. The two leaders stated that Israeli troops will remain stationed on the strategic ridge to prevent the Iran-aligned group from re-establishing its presence or rebuilding military capabilities in the border region.
The demolition targets one of the most heavily fortified positions along the border, located approximately 15 kilometers (10 miles) from Israeli territory near the city of Nabatieh. The operation marks a major step in Israel's efforts to consolidate a self-declared buffer zone in southern Lebanon. However, the move comes as a U.S.-brokered diplomatic framework established following a June ceasefire remains entirely stalled due to ongoing disputes over force withdrawals and militant disarmament.
Demolition of Subterranean Badr Unit Complex
According to details released by the Israeli military, the subterranean network extended for more than 2 kilometers (1.24 miles) beneath the Ali al-Taher ridge. Israeli forces systematically inspected and dismantled the structure after establishing physical control over the subterranean passages. Within the complex, troops uncovered a central command installation belonging to Hezbollah's specialized Badr unit. The facility included fortified command posts, extensive ammunition storage rooms, and fully equipped living quarters designed to allow fighters to stay underground for extended periods without surfacing.
During the clearing operations, Israeli forces seized substantial armaments stored within the tunnels. The military reported recovering dozens of rockets, missiles, and uncrewed aerial vehicles, alongside anti-tank guided missiles, landmines, and explosive devices. Reports citing Israeli sources noted that the bodies of dozens of Hezbollah fighters were located inside the subterranean chambers during the clearing process.
The final destruction of the installation generated widespread physical shockwaves across the region. Lebanon's official National News Agency reported that the Israeli military detonated a massive explosive charge at the ridge, causing ground tremors and sending loud blast waves echoing across the city of Nabatieh and adjacent towns in southern Lebanon.
Strategic Ridge and the Battle for High Ground
The Ali al-Taher ridge has emerged as a central focal point of military operations in southern Lebanon since conflict escalated dramatically on March 2. According to Lebanese security sources, Hezbollah began constructing the underground command facility and stockpiling heavy weaponry at the location in July. The high-altitude ridge offers clear sightlines over broad areas of southern Lebanon and northern Israel, making control of the terrain critical for artillery, surveillance, and defensive positioning.
The location sits near Beaufort Castle, a historic high-ground fortress that Israeli forces secured earlier in the conflict to command the surrounding territory. Defence Minister Israel Katz previously stated that Israeli forces had successfully driven Hezbollah fighters out of the tunnel network beneath the highland. Katz and Netanyahu reiterated that maintaining a permanent ground posture on the ridge is necessary to enforce Israel's security zone and eliminate cross-border firing positions.
Despite the scale of the demolition and the claims of complete operational control issued by Israeli officials, Hezbollah has not released an official statement responding to the destruction of the Ali al-Taher installation.
Stalled Diplomatic Framework and Disarmament Deadlock
The destruction of the underground complex exposes the complete halt in momentum for the diplomatic framework brokered by the United States following the June ceasefire. That agreement, negotiated between the governments of Israel and Lebanon without direct participation from Hezbollah, outlined a phased timeline requiring Israeli troops to gradually pull back from southern Lebanon while the Lebanese Armed Forces deployed south to disarm Hezbollah positions.
The implementation of the deal has reached a deadlock over fundamental disagreements regarding sequence and compliance. Hezbollah has repeatedly refused to surrender its arsenal or vacate its traditional operational zones in the south. In response, the Israeli government has maintained that its armed forces will not withdraw from any occupied border positions until Hezbollah is fully disarmed and removed from the frontier.
Since the initial push into southern Lebanon, Israel has progressively seized multiple strategic heights and fortified strongpoints. Israeli officials now explicitly frame these positions as a permanent security buffer, designed to prevent surprise incursions and protect civilian communities in northern Israel.
Regional Escalation Risks and Tehran's Warning
The ongoing military operations on the Ali al-Taher ridge carry wider geopolitical implications for the Middle East. Prior to the demolition, Iran reportedly issued a direct warning to the United States last month, stating that Tehran would respond forcefully if Israeli military actions against the Ali al-Taher ridge and surrounding high ground continued unabated.
The escalation along the ridge reflects broader regional volatility as Israel expands its military footprint in southern Lebanon while regional powers monitor the deteriorating ceasefire structure. With Israeli forces consolidating ground control and continuing structural demolitions, the implementation of the original U.S. diplomatic blueprint appears increasingly remote.
As of Thursday, Israeli forces remain deployed along the Ali al-Taher ridge, conducting ongoing site clearing and surveillance. Neither the Lebanese government nor international ceasefire monitors have announced a formal path forward to resume negotiations or resolve the military standoff in the border zone.
