In brief

Israeli Defence Forces have destroyed a large underground Hezbollah complex in southern Lebanon, reportedly using 1,000 tonnes of explosives to blast two 2‑km tunnels under the Ali Taher Ridge. The explosion triggered seismic activity equivalent to a 4.1‑magnitude earthquake. No immediate response came from Hezbollah or the Lebanese government, while residents reported shaking and evacuation. The strike comes amid renewed Israeli operations in the region, with casualties and displacement continuing under the current conflict.

Israeli Defence Forces (IDF) announced that it blew up a large underground complex run by Hezbollah in southern Lebanon, using more than 1,000 tonnes of explosives to crush two tunnels that stretch over 2 km beneath the Ali Taher Ridge.

The blast generated a seismic event equivalent to a 4.1‑magnitude earthquake, according to the US Geological Survey. The IDF claims the complex housed a command centre, dozens of rockets, missiles, UAVs and anti‑tank weapons.

Hezbollah and the Lebanese government did not immediately respond to the IDF statement. Local residents in Nabatieh reported a “terrifying” explosion sound and shaking comparable to an earthquake, with people fleeing to Beirut.

The strike comes amid a renewed campaign in southern Lebanon, where Israeli forces have extended their occupied “security zone” since the March 2026 war began. Other Israeli attacks were reported in Nabatieh, Tyre, and Mansouri districts during the same week.

Since the conflict began on 2 March, the UN estimates about 330,000 people remain displaced in Lebanon, with Israeli air strikes and restrictions on returning to occupied areas cited as key obstacles.

Israel maintains that it will continue to hold the southern Lebanese territory until Hezbollah disarms, while the Lebanese army is gradually redeploying to the area. As of now, the death toll in Lebanon from Israeli attacks stands at 4,383, including women and children.
