Israel's military said Monday it had killed a Hezbollah operative in southern Lebanon, a region that has witnessed several attacks despite the ceasefire between Israel and the Iran-backed group.

"Yesterday evening (Sunday)... The IDF struck and eliminated Hezbollah terrorist Muhammad Ali Shuweikh in the Mansouri area in southern Lebanon," the military said in a statement.

The U.N. peacekeeping force in Lebanon said Israeli soldiers shot at its troops on Sunday in the south of the country, while Israel's military said it mistook blue helmets for "suspects" and fired warning shots.

The Israeli military blamed "poor weather conditions" and said it had not deliberately targeted U.N. troops.

Lebanon will file a complaint to the United Nations Security Council decrying that Israel is building walls in south Lebanon, an accusation Israel has denied, the Lebanese presidency said.

The United Nations Interim Force in Lebanon (UNIFIL) said on Friday that the Israeli army had built walls in south Lebanon near the U.N.-demarcated Blue Line, the de facto border.

The U.S. Embassy in Beirut has announced the November 14 arrival of U.S. Ambassador-Designate Michel Issa in Lebanon.

"Ambassador Issa had a distinguished former career in banking, where he spent two decades excelling as a currency trader, managing trading floors, and leading initiatives in credit and compliance before transitioning to a successful career in the automobile industry," the Embassy said in a statement.

The Israeli army on Friday claimed that it has managed to confirm that Hezbollah’s so-called Unit 121 was behind the 2023 “assassination” of Lebanese Forces official Elias Hasrouni in south Lebanon’s Bint Jbeil district.

“This comes contrary to the rumors spread by Hezbollah, which claimed that he was killed in a traffic accident. Hasrouni, aged 70 when he was assassinated, was known for his stance that fiercely opposes Hezbollah,” Israeli army Arabic-language spokesman Avichay Adraee said in a post on X.

Saudi Ambassador to Lebanon Walid Bukhari on Friday said that “Lebanon is a message” and that “it is not a minor thing that Pope Leo’s first foreign visit will be to it.”

“Lebanon will witness great prosperity and I don’t see pessimism,” Bukhari added, during a visit to the headquarters of the Press Editors Syndicate.

French President's advisor Anne-Claire Legendre has reiterated during a visit to Lebanon her country's readiness to provide all the necessary maps and documents to facilitate the border demarcation between Lebanon and Syria, Foreign Minister Youssef Rajji said.

Meanwhile al-Jadeed TV reported that a Lebanese-Syrian meeting on the demarcation between the two countries will be held in December, under the auspices of the United Nations.

UNIFIL said Friday that its troops conducted last month a geospatial survey of a concrete T-wall erected by the Israeli army southwest of the Lebanese border town of Yaroun.

“The survey confirmed that the wall crossed the Blue Line, rendering more than 4,000 square meters of Lebanese territory inaccessible to the Lebanese people,” UNIFIL said in a statement.

The situations in the South “will change with the presence of the army,” whose strength “stems from its legitimacy and people’s embracement and firm confidence,” President Joseph Aoun said on Friday.

“The order for the army to confront any Israeli land incursion was aimed at sending a message to everyone that the army has become in charge of decisions in the South and is tasked with protecting it,” the president added.

French President's advisor Anne-Claire Legendre met Friday with Hezbollah's head of Arab and International Relations Ammar al-Moussawi, al-Manar TV said.

Legendre and al-Moussawi discussed Israel's violations of a ceasefire agreement reached in November last year, with al-Moussawi urging France to pressure Israel to halt its attacks.
