The U.S.-led Mechanism committee will meet Wednesday in Ras al-Naqoura for the first time since December 19, al-Akhbar newspaper reported.

It quoted informed sources as saying that the meeting will be limited to military personnel in the vein of the previous meeting.

The army accused the Israeli military on Tuesday of firing near a position it was setting up in the country's south, saying it had instructed troops to return fire.

In a statement, the Lebanese army said it was "establishing a new observation post on the southern border" when "the area surrounding the post was subjected to gunfire from the Israeli side".

Foreign minister Youssef Rajji said Tuesday that Lebanon fears its infrastructure could be hit by Israeli strikes if the situation with Iran escalates.

Rajji said Lebanese authorities had appealed to Hezbollah, which has fought several wars with Israel, most recently in 2024, not to respond in any way that could trigger “bad situations” for Lebanese civilians.

Prime Minister Nawaf Salam has called on Hezbollah not to drag the country into "a new adventure", as he re-affirmed the state's commitment to disarm the group.

"The Gaza adventure came at a great cost to Lebanon, and we hope we won't be dragged into a new one," he said as tensions escalated between the U.S. and Iran, with Hezbollah chief Naim Qassem saying that any attack on Iran would also be an attack on Hezbollah.

Al Habtoor Group said Monday that it has appointed one of the world’s leading international law firms specializing in sovereign disputes and treaty-based investment arbitration, to take legal action against Lebanese authorities over claims of investment losses of $1.7 billion.

Al Habtoor said it has entered the final stages of preparation for the commencement of international arbitration proceedings in Washington, D.C.

Parliament Speaker Nabih Berri does not seem concerned about a possible spillover of the U.S.-Iran conflict into Lebanon, sources told Asharq Al-Awsat newspaper.

The sources said they sensed from Berri's attitude that Hezbollah will not take any action in the event of a strike on Iran.

U.S. Ambassador Michel Issa and Saudi Ambassador Walid Bukhari have openly raised the issue of postponing the parliamentary elections with Speaker Nabih Berri but he did not show cooperation, al-Akhbar newspaper reported.

A U.S. State Department official said the U.S. has ordered nonessential diplomats and family members to leave Lebanon as tensions over Iran rise with the threat of a potentially imminent military strike.

The official said a continuous assessment of the regional security environment determined it was “prudent” to draw down the U.S. Embassy’s footprint so that only essential personnel remained at their posts.

Hezbollah chief Sheikh Naim Qassem has emphasized that the 2025 funeral ceremony of slain Hezbollah leaders Sayyed Hassan Nasrallah and Sayyed Hashem Safieddine was “a pledge and renewal of the covenant to continue the resistance, a reclaiming of the initiative in rebuilding the resistance’s capabilities, and a reaffirmation of popular unity around it.”

In an interview with the Hezbollah-affiliated al-Ahed news portal marking the funeral’s first anniversary, Qassem pointed out that “its political significance is that the resistance continues -- leadership, fighters and people alike.”

Speaker Nabih Berri on Monday clarified that he has said that “the atmosphere of the five-nation group for Lebanon is in favor of postponing the elections.”

Berri added that he has not at all mentioned “any ambassador, neither from the Quintet, nor from other sides.”
