The IDF has uncovered and destroyed what it described as the largest Hezbollah underground tunnel network identified to date in southern Lebanon, a sprawling system stretching roughly two kilometers and reaching depths of up to 25 meters.
The tunnel, located in the Qantara area and discovered during operations by the 36th Division, was built over years with Iranian backing and served as a major operational hub for Hezbollah’s elite Radwan forces, according to the military.
Inside, troops found an extensive underground complex comprising around 30 living quarters, along with showers, kitchens, and fortified corridors carved into hard granite rock. The network was accessible through approximately 30 vertical shafts and split across two main axes, allowing movement through wide passageways that could accommodate motorcycles.
The IDF said the site contained large quantities of weapons and equipment and was designed to house and support hundreds, potentially thousands, of terrorists. Military officials described it as a central staging ground where Hezbollah fighters could gather, arm themselves, and disperse through multiple exits to carry out attacks.
Evidence at the site pointed to Iranian involvement, including symbols and materials associated with the regime, reinforcing assessments that the project was carried out with direct guidance and support from Tehran.
The network was discovered by the 7th Brigade and the elite Yahalom combat engineering unit following intelligence gathered over an extended period. Forces first located one of the tunnel entrances before securing the surrounding area and methodically clearing the system of militants, explosives, and infrastructure.
Engineers then carried out a complex demolition operation, inserting hundreds of tons of explosives into the network. Due to the tunnel’s depth, length, and construction within solid rock, approximately 450 tons of explosives were used to ensure its complete destruction.
The IDF said the system was part of Hezbollah’s broader plan to establish underground infrastructure near the Israeli border as part of a potential offensive into northern Israel.
