Israeli ground forces crossed the Litani River and seized Beaufort Castle over the weekend, capturing the 12th-century hilltop fortress that Israel last held when it withdrew from Lebanon in 2000 and marking the deepest Israeli incursion into the country in 26 years.
The advance vaults past the boundary Israel itself had defined as the goal of its current campaign and converts a border operation into something closer to a buffer-zone occupation. Israeli forces now hold about 2,000 square kilometres, or 770 square miles, of Lebanese territory, roughly a fifth of the country, and on Sunday the military ordered all residents south of the Zahrani River, about 10 kilometres beyond the Litani, to move north or risk being killed.
What changed
The seizure of Beaufort Ridge follows a midweek push past the Israel-declared yellow line six miles inside Lebanese territory and Friday's first ground crossing of the Litani since 2006. Prime Minister Benjamin Netanyahu announced the capture Sunday and tied it to a broader expansion of war aims.
"Our heroic fighters captured the Beaufort outpost," Netanyahu said, adding that "the occupation of Beaufort is a dramatic stage and a dramatic change in the policy that we are leading." He said his instruction to the military was to "deepen and expand" Israel's grip on areas previously under Hezbollah control.
Defense Minister Israel Katz said the Israeli flag was "once again flying over the peaks overlooking the communities of the Galilee" and that the soldiers who took the fortress "will remain there as part of the security zone in Lebanon." Katz vowed on X that Israel would "crush" Hezbollah.
On the map
Beaufort sits roughly 15 kilometres north of the Israeli border and commands routes linking southern Lebanon to the western Bekaa Valley and the city of Nabatieh, the Shia-majority hub of the south. Israeli troops have reached Nabatieh's outskirts, and the military has issued blanket evacuation orders for the city and the coastal city of Tyre.
Imad Salamey, an international relations professor at the Lebanese American University, told Al Jazeera that pushing on Nabatieh would signal Israeli objectives "have evolved from the original goal of pushing Hezbollah north of the Litani into a broader campaign aimed at dismantling [Hezbollah's] entire territorial and communal infrastructure."
The toll
Lebanon's health ministry says Israeli strikes have killed more than 3,350 people since March 2, when Hezbollah opened fire in support of Iran. Israel says 25 of its soldiers and two civilians have been killed in or near southern Lebanon over the same period. More than 1.2 million Lebanese have been displaced.
Lebanese Prime Minister Nawaf Salam has accused Israel of a "scorched-earth policy" and of inflicting "collective punishment." French Foreign Minister Jean-Noel Barrot requested an emergency United Nations Security Council session, telling BFMTV that "nothing can justify" Israel's "ever-deeper occupation" of Lebanese territory. Israeli and Lebanese officials met at the Pentagon on Friday under U.S. mediation; talks are expected to resume next week.
The Lebanon offensive also threatens the parallel U.S.-Iran track. Iran has said any extension of its own ceasefire with Washington must include an Israeli halt in Lebanon, and a senior Arab mediator told NBC News that a U.S.-Iran truce text agreed in Doha is now stalled.
The counterpoint
Israeli government and center-right framing was largely unavailable by press time: BBC, Reuters, AP and Guardian feeds did not come through, and today's reporting reaching the desk is lean-left. Within those sources, the affirmative case came from Katz, who described Beaufort as "one of the most important strategic points for defending the communities of the Galilee," and from Finance Minister Bezalel Smotrich, who called the seizure a correction of "old national sins." Fawaz Gerges of the London School of Economics, quoted in NBC News, made the opposite case on its own terms: that Israel can hold a "massive swath" of Lebanon but risks a "forever war" in which Hezbollah continues to harass settlements regardless of the depth of any security zone.
Negotiators are scheduled to return to Washington next week. Whether they meet across a line at the Litani, the Zahrani, or somewhere further north will depend on what Israeli troops do between now and then.
