Israel said it destroyed Hezbollah underground infrastructure near Nabatiyeh on Sept. 10, 2026.
Why it matters: The operation targeted a fortified cross-border site in southern Lebanon that Israel says had been used by Hezbollah for years. Reporting also says the blast was powerful enough to register as a 4.1 earthquake.
- Israel said on Sept. 10, 2026, it destroyed underground Hezbollah infrastructure beneath the Ali al-Taher ridge near Nabatiyeh.
- The IDF said the site included command centers, weapons storage and living quarters for Hezbollah's Badr unit.

Israel said it destroyed what it called Hezbollah underground infrastructure beneath the Ali al-Taher ridge in southern Lebanon, near Nabatiyeh. In an IDF press release, the military said the underground routes had been fully dismantled and described the site as strategic infrastructure built over two decades and funded and planned by Iran. The IDF press release said the facility included command centers, weapons storage and living quarters for Hezbollah's Badr unit.
Multiple reports said the demolition produced a blast strong enough to register as a magnitude 4.1 earthquake in southern Lebanon. L'Orient Today reported the seismic reading, while The Times of Israel liveblog said Israel used more than 1,100 tons of explosives and that the main tunnel system stretched more than 2 kilometers. The same report said the wider Ali Taher/Beaufort complex totaled eight tunnels and 5.4 kilometers.
Reuters reported that Israel tied the strike to consolidating a security zone in the area. AP reported on Sept. 11 that Israeli officials had blown up Hezbollah tunnel networks under the ridge and described the site as one of the most contested parts of the front in southern Lebanon.
By the numbers
- 4.1 - reported earthquake reading in southern Lebanon after the blast
- 1,100+ tons - amount of explosives The Times of Israel said Israel used
- 2 kilometers - length of the main tunnel system reported by The Times of Israel
Yes, but: The seismic reading and tunnel measurements were reported by outlets based on Israeli accounts and have not been independently verified in the dossier.
