Tensions between Israel and Hezbollah have simmered for years along the southern Lebanese border, with both sides maintaining fortified positions. The Ali Al-Taher ridge became particularly contested, serving as a significant stronghold for Hezbollah's operations in the region.
In early September 2026, Israeli forces launched a focused military operation to seize control of the ridge. The move came amid ongoing cross-border skirmishes and a backdrop of international diplomatic efforts aimed at easing hostilities.
How it unfolded
On September 7, reports emerged that Israel had taken control of the Ali Al-Taher ridge in southern Lebanon, a strategic location long held by Hezbollah. This marked a major shift in the local balance of power.
By September 8, Israeli military sources described the ridge as Hezbollah's last significant stronghold in the area, noting a sharp decline in the group's activities nearby.
On September 10, Israeli leaders announced the destruction of Hezbollah's underground infrastructure at the ridge. The tunnels, reportedly built with Iranian support over twenty years, were targeted with powerful explosives. The resulting blasts caused a 4.1-magnitude tremor, which was recorded by the US Geological Survey and felt as far as Saida, some 40 kilometers from Beirut.
Remains of fighters were reportedly found in the destroyed tunnels. Lebanese authorities and local media described the explosions as massive, with significant shockwaves impacting the surrounding region.
The operation has drawn international attention, as it occurred during US-backed negotiations over security arrangements along the Lebanese-Israeli border.
Where it stands
Israel now claims operational control over the Ali Al-Taher ridge, having demolished what it says was Hezbollah's key underground infrastructure. Hezbollah's presence and activity in the immediate area have been significantly reduced.
The destruction of the tunnels and the visible show of force have complicated ongoing diplomatic talks. Lebanese officials and analysts are questioning Israel's intentions and raising concerns about the implications for Lebanon's sovereignty and border stability.
What to watch
Attention is now focused on whether Israel will maintain its new positions or face international pressure to withdraw. The fate of US-backed negotiations and the potential for renewed Hezbollah activity remain open questions. Regional stability could hinge on how both sides and their allies respond in the coming weeks.
