TheIsrael–Lebanon barrier, also called theInterlocking Stone (Hebrew:אבן משתלבת), is aborder barrier built by theIsrael Defense Forces along theIsrael–Lebanon border. The barrier includes fences, a wall 7–9 metres high, embankments,pillbox towers, and dozens ofwatch towers. The barrier is similar in nature to theGaza–Israel barrier.
In September 2018, the Israeli government announced plans to construct a concrete barrier along the Lebanese border to prevent infiltration fromHezbollah into Israel.[1][2]
In April 2020, Israel completed an additional 15 km (9.3 mi) of the barrier out of the whole border length of 130 km (81 mi). The completed section includes about 5.2 km (3.2 mi) fromRosh HaNikra toShlomi, and another 4.6 km (2.9 mi) nearMetula andMisgav Am. The other sections under construction include a wall and underground sections. There has been claims that the management is 1.7 billionshekels short of the amount needed to complete the barrier along the entire border.[3]
In November 2025, Lebanon filed a complaint against Israel to theUnited Nations Security Council over the barrier.[4] Lebanon claimed that Israel's construction of the barrier crossed into Lebanese territory.UNIFIL observers concluded the barrier made 4,000 km2 (1,500 sq mi) of Lebanese territory inaccessible to Lebanese residents. However, Israel denies that the barrier ever crosses theBlue Line.[5]
