Israeli Defense Forces announced Sunday that troops operating in the Mount Dov region of southern Lebanon successfully located and dismantled a massive Hezbollah underground terror tunnel stretching roughly 100 meters beneath rugged border terrain. According to the IDF, the tunnel contained four separate hideout rooms used by Hezbollah operatives, highlighting what Israeli officials say is the terror group’s continued effort to maintain military infrastructure dangerously close to Israel’s northern frontier despite ongoing ceasefire agreements.

Dramatic aerial footage released from the operation showed a powerful controlled explosion tearing through the tunnel complex and sending enormous smoke plumes rising above the mountainous landscape. Israeli military officials stressed that the mission was carried out as part of ongoing defensive operations targeting remaining Hezbollah threats under the U.S.-brokered ceasefire established in April 2026, which requires Hezbollah forces to withdraw north of the Litani River and halt military activity near the Israeli border.

Supporters of Israel praised the operation as another critical step in preventing future cross-border attacks and dismantling Iranian-backed terror infrastructure embedded across southern Lebanon. Pro-Israel voices argued that the IDF’s continued vigilance is essential to protecting Israeli civilians from Hezbollah’s expanding underground networks, warning that failure to eliminate hidden weapons sites and tunnels would leave northern communities exposed to renewed rocket fire and infiltration attempts.
