Ali Taher ridge
The Ali Taher ridge is a strategically dominant terrain feature in southern Lebanon's Nabatieh District, rising to 697 meters and serving as a critical observation and fire-control point overlooking the city of Nabatieh. It is the site of a massive, Iranian-built underground fortress and has been a focal point of intense IDF operations to dismantle Hezbollah's regional command infrastructure.
The Ali Taher ridge is one of the most significant topographical features in the Nabatieh sector of southern Lebanon. Located north of the Litani River and approximately two kilometers north of the historic Beaufort Castle, the ridge rises to an elevation of roughly 697 meters. Its height provides a commanding view of the Nabatieh plateau and the city of Nabatieh itself, which has long served as a primary urban hub and military stronghold for Hezbollah. Historically and tactically, the ridge separates the Litani River valley from the northern Nabatieh highlands, making it a gateway for any military maneuver seeking to neutralize threats emanating from the central sector of southern Lebanon.
In mid-2026, the ridge became a focal point of intense combat during the IDF's ground maneuver. Intelligence reports revealed that the ridge housed a massive underground fortress (UGF) constructed by Iran's Islamic Revolutionary Guard Corps (IRGC) starting in 2014. This subterranean complex, which includes the reported 'Imad 4' missile city, served as the headquarters for Hezbollah's Badr Unit and functioned as a central command-and-control node and weapons depot. The site was heavily fortified with a network of tunnels and anti-tank missile positions designed to obstruct Israeli advances.
During the final hours before a purported ceasefire on Friday, June 19, 2026, IDF armored and infantry units engaged in fierce close-quarters combat to consolidate control over the ridge. The battle claimed the lives of the 52nd Battalion commander and three additional soldiers when their tank was hit. Despite the official start of a truce, the IDF maintained operational freedom of action to dismantle the extensive terror infrastructure. In late July 2026, the IDF successfully destroyed a major tunnel route on the ridge that originated under the Beaufort ridge and extended north of Nabatieh. The capture and subsequent neutralization of Ali Taher, which the IDF has renamed 'Ma'ale Tahara,' is viewed as a critical step in establishing fire-control over Hezbollah's logistics and command centers in the district.
