The United Nations has expressed concern over Israel's ongoing demolitions in southern Lebanon despite a ceasefire in its war with Hezbollah.

"The scale of the detonations and demolitions taking place in south Lebanon is deeply concerning, with a devastating impact on civilian infrastructure, cultural heritage, and the collective memory of communities," the office of the U.N. special coordinator for Lebanon said in a statement.

The Israeli military said on Saturday that it killed several Hezbollah fighters in southern Lebanon and that an Israeli soldier was injured there despite a ceasefire.

Jean Arnault, Officer-in-Charge of the Office of the United Nations Special Coordinator for Lebanon (UNSCOL), has congratulated the Lebanese Armed Forces (LAF) and its Commander, servicemen and servicewomen on the occasion of the eighty-first Army Day, stressing that the army has "earned the pride of the nation and the trust of the international community."

President Joseph Aoun has warned that Israeli detonations near a UNESCO-listed castle  threatened a recent deal with Israel, which in turn said it had razed Hezbollah tunnels there.

Speaker Nabih Berri’s meeting with President Joseph Aoun was to “clarify that Israel has no intention of actually withdrawing from Lebanon, and that Israel's non-compliance will prevent the agreement from being implemented,” visitors of Berri quoted him as saying, according to al-Akhbar newspaper.

Speaker Nabih Berri condemned Friday Israeli detonations near the UNESCO-listed Beaufort Castle, and in the towns of Arnoun, Kfartibnit, Yohmor al-Shqif, and Hadatha in south Lebanon.

Israel said it destroyed tunnels used by Hezbollah in the Beaufort area using approximately 700 tons of explosives. The tremors from these explosions were felt in the south, and even in the capital Beirut, Berri said, adding that these condemned actions are unacceptable and must not be met "with silence" or treated as a fait accompli.
