In mid-September 2026, the IDF announced the destruction of a tunnel network on the Ali al Taher ridge, consisting of eight routes totaling over 5,400 meters. The detonations were significant enough to be recorded as a 4.1 magnitude seismic tremor by the United States Geological Survey. Following these actions, the IDF reported discovering additional fighting positions, including a tunnel shaft and a rocket launcher containing 32 rockets aimed at Israeli territory. The military stated that the 401st Brigade completed an eight-month mission in the region, claiming to have dismantled over 1,200 Hezbollah infrastructure sites and recovered more than 600 weapons. Amidst these military developments, Lebanese Interior Minister Ahmad al-Hajjar indicated that Lebanon is engaged in direct negotiations with Israel under United States auspices. These discussions aim to facilitate the withdrawal of Israeli forces from southern Lebanon, the deployment of the Lebanese army, and the return of residents to their villages. ## Timeline ### 2026-09-15: IDF discovers Hezbollah rocket launcher and tunnel in southern Lebanon The IDF discovered a loaded Hezbollah rocket launcher and tunnel in southern Lebanon, while Lebanese officials confirmed ongoing direct negotiations with Israel mediated by the U.S. 3 sources. https://clstr.news/cluster/idf-discovers-hezbollah-rocket-launcher-and-tunnel-in-southern-lebanon ### 2026-09-13: Israel destroys Hezbollah tunnel network in southern Lebanon Israel destroyed a 5,400-meter Hezbollah tunnel network on Lebanon's Ali al Taher ridge, triggering a 4.1 magnitude tremor detected by the USGS. 8 sources. https://clstr.news/cluster/israel-destroys-hezbollah-tunnel-network-in-southern-lebanon-7 --- Cite as: Israel-Hezbollah conflict in southern Lebanon.
