Implementation of the U.S.-brokered framework agreement between Lebanon and Israel is expected to begin within three weeks despite remaining disputes between the two sides, according to an assessment by an Israeli security official cited by Israeli news website Walla.

The report said Israeli forces would begin a gradual withdrawal from the agreed-upon "pilot zones" in southern Lebanon as part of the arrangement.

Under the plan, the Lebanese Armed Forces would deploy to the areas vacated by Israeli troops and work to dismantle military infrastructure and remove armed operatives, in line with the terms of the agreement.

The report comes as Lebanon and Israel continue discussions, with U.S. mediation, over the implementation of a framework agreement aimed at securing an Israeli withdrawal from parts of southern Lebanon and strengthening the ceasefire along the border.

Separately, Israeli military spokesman Lt. Col. Avichay Adraee renewed accusations that Hezbollah had used Beaufort Castle, known in Lebanon as Qalaat al-Shakif, for military purposes with Iranian backing.

In a post on X, Adraee alleged that Hezbollah had transformed the historic fortress—one of southern Lebanon's most prominent archaeological landmarks—from a state-owned heritage site into a military position.

He said converting national heritage and archaeological sites into military installations constitutes a violation of Lebanon's sovereignty.

Adraee also rejected Hezbollah's denial of the allegations, saying the group's statements did not alter what he described as documented facts on the ground.

The accusations came a day after the Israeli military said it had uncovered an extensive Hezbollah tunnel network beneath the Beaufort Ridge during operations in southern Lebanon. Israeli officials said the underground complex had been built with direct Iranian assistance and had served as a strategic base for launching attacks against northern Israel.
