Israel holds Ali al‑Taher ridge

What's happened

Israel has demolished a vast Hezbollah tunnel complex beneath the Ali al‑Taher ridge in southern Lebanon, using more than 1,000 tonnes of explosives to collapse tunnels that extended over 2km. The blast has registered as a 4.1‑magnitude tremor, Israeli forces say they have established operational control and will hold a security zone while continuing strikes when needed.

What's behind the headline?

What happened and why it matters

• Israeli forces have cleared and destroyed strategic underground infrastructure on the Ali al‑Taher ridge, using a large explosive demolition that triggered seismic tremors. This completes what the military called a campaign to remove tunnels and command facilities that threatened northern Israel.

Who is driving events

• Israel is driving the operation to deny Hezbollah an ability to reconstitute a cross‑border fighting capability. Politicians including Defense Minister Israel Katz have framed the seizure as establishing a permanent security zone.

Immediate consequences

• Israel will hold operational control of the ridge and sustain strikes to prevent reconstruction. Lebanon is already reporting civilian displacement and shock from the blast; humanitarian strain in southern Lebanon will increase.

Strategic trajectory

• The move will harden Israel's negotiating stance in US‑brokered talks over a phased withdrawal and Hezbollah disarmament. If Israel continues to expand and hold terrain, the framework agreed in June will stall further and regional tensions will rise.

Forecast

• Israel will use the ridge as a forward buffer that will force Hezbollah to either accept a weakened posture or escalate attacks elsewhere. The continued occupation of small Lebanese areas will prolong instability and complicate US mediation.

What to watch next

• Track whether Lebanese authorities or Hezbollah respond with cross‑border strikes, and whether the US or other mediators press for immediate de‑escalation. Monitor humanitarian reports from Nabatieh and nearby towns for displacement and civilian casualties.

How we got here

The action follows months of fighting between Israel and Hezbollah that resumed in March 2026. A US‑brokered framework reached in June called for Hezbollah disarmament and Israeli withdrawal from southern Lebanon; progress has stalled and Israel has expanded an on‑ground security zone.

Our analysis

The BBC reported that Israeli forces used more than 1,000 tonnes of explosives to destroy two tunnels spanning over 2km and that the blast triggered seismic activity equivalent to a 4.1 magnitude quake. The BBC quoted residents saying “the house shook all together as if it was literally an earthquake.” Arab News and the Independent described the operation as completing seizure of the ridge and establishing a security zone; Arab News quoted Defense Minister Israel Katz saying Israel is “ready and prepared to continue the campaign.” The Times of Israel and Al Jazeera published the ministerial intent to annex or hold territory as a punitive measure and to prevent future attacks: The Times recorded Smotrich’s comments advocating annexation up to the Yellow Line and the Litani; Al Jazeera noted his call to “do there what we did in Gaza.” The New York Post and other outlets provided political context about Israel’s wider campaign and electoral tensions, but the core operational details—explosive demolition, tunnel destruction, and seismic readings—are consistent across BBC, Independent, Arab News and BBC Business. Readers should consult the BBC for eyewitness description of the blast, Arab News for official Israeli statements including Katz’s remarks, and the Independent for the military’s claim of underground command centres and weapons stores.

  The Gaza Health Ministry (GHM), officially the Palestinian Ministry of Health – Gaza, is responsible for managing healthcare and medical services in the Gaza Strip. The health ministry's casualty reports have received significant attention during the course of the Gaza–Israel conflict. Its numbers have historically been considered reliable by the United Nations, the World Health Organization, and Human Rights Watch. In relation to the Gaza war, two letters published in The Lancet journal did not find evidence of inflation or fabrication of Palestinian casualty numbers. A peer-reviewed analysis published by The Lancet in January 2025 concluded the GHM had undercounted deaths due to traumatic injury by 41% in its reports on the Gaza war, with the total estimated traumatic injury deaths as of October 2024 probably exceeding 70,000 as opposed to the GHM's reported 41,909—59.1% of them being women and children and the elderly. Another independent peer-reviewed analysis of casualties was published in The Lancet by Michael Spagat and other researchers. They estimated 75,200 violent deaths and 8,540 excess non-violent deaths between 7 October 2023 and 5 January 2025. The estimate of violent...
