Israeli forces obliterate vast Hezbollah subterranean complex in southern Lebanon, triggering significant seismic activity

The Israeli military has confirmed the destruction of an extensive underground facility operated by Hezbollah in southern Lebanon, a strategic operation that involved a massive detonation and resulted in seismic activity felt across the region. The complex, located beneath the Ali Taher Ridge, was reportedly dismantled using over 1,000 tonnes of explosives, targeting two tunnels spanning more than 2 kilometers (1.2 miles).

This powerful blast registered as a magnitude 4.1 earthquake by the US Geological Survey, underscoring the immense scale of the military action. The event sent shockwaves through local communities, prompting widespread alarm and evacuations as residents experienced their homes shaking violently.

The operation marks a significant development in the ongoing conflict in southern Lebanon, where Israeli forces have been engaged in prolonged fighting with the Iran-backed group. Israeli control over the Ali Taher Ridge was established recently, following months of intense clashes.

Massive detonation reverberates across border region

Eyewitnesses in Nabatieh, approximately 6 kilometers west of the ridge, described a dramatic scene as the sky illuminated with a fireball before a terrifying sound engulfed the area. Residents recounted their houses shaking as if struck by an actual earthquake, causing widespread panic.

The immediate aftermath saw people screaming and children crying, with roads quickly becoming congested as families sought safety by leaving the area for Beirut. The tremors were so powerful that they were reportedly felt as far north as Saida, a coastal city located 40 kilometers away from the blast site, highlighting the immense energy released during the demolition.

Strategic infrastructure targeted in southern Lebanon

According to statements from the Israel Defense Forces (IDF), the obliterated subterranean infrastructure served as a critical command center for Hezbollah’s Badr unit. This complex was not merely a tunnel network but a sophisticated facility designed for military operations.

The IDF further detailed that the underground site housed a substantial arsenal, including dozens of rockets, missiles, and unmanned aerial vehicles. Anti-tank weapons, various types of mines, and additional explosives were also discovered within the complex, underscoring its pivotal role in Hezbollah’s operational capabilities.

Israeli military officials emphasized that this infrastructure represented a strategic asset, meticulously constructed over two decades with funding and planning provided by what they termed the “Iranian terror regime.” The IDF asserted that all militants present within the facility were either neutralized or managed to flee prior to the detonation, ensuring the successful elimination of the operational base.

Escalating conflict and regional implications

This latest action by Israeli forces completes a broader mission aimed at destroying eight identified tunnels and establishing a “security zone” in the area adjacent to the border. The ongoing operations reflect a renewed intensity in the fighting across southern Lebanon, where Israeli forces continue to expand their positions against Hezbollah targets.

The conflict in Lebanon became intertwined with broader regional tensions following a significant escalation in March, when Hezbollah launched rockets into Israel. This was in retaliation for a strike that resulted in the death of a prominent Iranian leader, drawing Lebanon deeper into a complex web of conflict involving Israel, the United States, and Iran.

While a ceasefire agreement between Iran and the US, alongside a separate pact between Lebanon and Israel, had led to a reduction in hostilities in June, Israeli strikes and demolition activities in southern Lebanon have persisted. Under the framework of the Lebanon-Israel agreement, Hezbollah is expected to disarm, and Israeli forces are slated for a gradual withdrawal, with the Lebanese army deploying across the region.

However, Hezbollah was not a direct party to this agreement and has consistently rejected any direct negotiations, indicating ongoing challenges to implementing a lasting peace. The current Israeli occupation encompasses roughly 5% of Lebanese territory, a substantial swathe captured since the renewed conflict.

Civilian impact and regional displacement

The intense military activity has had a profound impact on the civilian population in southern Lebanon. Local media outlets reported fresh Israeli strikes in other southern areas on Thursday, including Nabatieh al-Fawqa and Mansouri in the Tyre district, demonstrating the widespread nature of the hostilities.

In response to the escalating situation and to reassure its citizens, the Lebanese army has increased its deployments in areas outside Israeli control. This includes the southern city of Nabatieh, where efforts are underway to strengthen stability and provide a sense of security to residents living under the shadow of conflict.

Military objectives and security zone establishment

The destruction of the Hezbollah complex underscores Israel’s commitment to neutralizing what it perceives as immediate threats emanating from southern Lebanon. The IDF’s declared objective of establishing a security zone aims to create a buffer against future incursions and attacks, reflecting a long-standing security doctrine in the region.

This strategy involves not only the physical elimination of militant infrastructure but also a broader effort to degrade Hezbollah’s capabilities and presence near the Israeli border. The scale of the explosives used and the resulting seismic activity highlight the comprehensive and forceful nature of these military operations, intended to send a clear message regarding Israeli resolve.

Ongoing hostilities and casualty toll

The human cost of the renewed fighting in Lebanon has been severe. The health ministry there reports that at least 4,362 people have been killed during the conflict, a figure that includes 395 women and 259 children, though it does not distinguish between combatants and civilians.

On the Israeli side, authorities have reported the deaths of 40 soldiers and four civilians. These figures underscore the tragic toll of the prolonged hostilities, highlighting the significant human impact on both sides of the border as the conflict continues to unfold.
