U.S. diplomat Morgan Ortagus is set to visit Lebanon at the end of the week with Commander of U.S. Central Command (CENTCOM) for high-level security meetings, LBCI said in a report Tuesday.

The meetings will focus on coordination and regional security concerns and will be held with Lebanese security officials, with no scheduled meetings with political leaders, LBCI said.

As political tensions boil over ahead of a Cabinet session that will discuss Friday a plan prepared by the army to implement the state's monopoly on arms, divisions are growing in the crisis and war-hit country, with no way out in sight.

According to a report published Tuesday in pro-Hezbollah al-Akhbar newspaper, Amal and Hezbollah's ministers might boycott the session Friday if its agenda is limited to discussing the disarmament plan.

The plan requested by the government for monopolizing arms before the year’s end was finalized by the Lebanese Army’s command more than two weeks ago, media reports said.

“The plan contains stages and timetables for executing each stage,” Asharq al-Awsat newspaper reported on Tuesday.

Palestinian President Mahmoud Abbas has said that he is “determined to withdraw all Palestinian arms from Lebanon,” after his Fatah Movement handed over weapons from several Palestinian refugee camps in Beirut’s southern suburbs and south Lebanon.

“The talk about disarming the camps in Lebanon started 15 years ago … The disarmament of Palestinian camps is a prelude to protecting Lebanon,” Abbas said in an interview with Al-Arabiya television.

Lebanon and Syria will form two committees to decide the fate of the nearly 2,000 Syrian prisoners held in Lebanese jails, locate Lebanese nationals missing in Syria for years and settle the shared unmarked border, judicial and security officials said.

Monday's announcement came as a Syrian delegation, which included two former Cabinet ministers and the head of Syria's National Commission for Missing Persons, visited Beirut, a first since insurgent groups overthrew Syrian President Bashar Assad's government in early December.

Since the fall of Bashar Assad's government in December, some 850,000 Syrian refugees have returned home from neighboring countries and the figure could reach 1 million in the coming weeks, a top official with the U.N. refugee agency said Monday.

Deputy High Commissioner of UNHCR Kelly T. Clements told The Associated Press in Damascus that about 1.7 million people who were internally displaced during the 14-year-old conflict have returned to their communities as the interim central government now controls large parts of Syria.

MP Melhem Riachi of the Lebanese Forces has said that “the positive point in Speaker Nabih Berri’s speech (on Sunday) was his talk about a Shiite desire for resolving the issue of arms.”

“The president and the prime minister must capitalize on this development,” Riachi said in an interview with Radio Free Lebanon.

Diplomatic efforts to cool political tensions are ongoing, ahead of a Cabinet session that will discuss Friday a plan prepared by the army to implement the state's monopoly on arms, Asharq al-Awsat newspaper said Monday.

The daily quoted a minister as saying that Amal and Hezbollah's ministers will attend Friday's session, securing a "full quorum", and that Hezbollah has no intention to boycott it and call for street protests on Friday.

Lebanon's Central Bank is trying to address the issue of Hezbollah-affiliated Al-Qard Al-Hasan financial institution, Finance Minister Yassin Jaber told Saudi news interactive channel al-Hadath.

In July, the Central Bank prohibited all licensed financial institutions in Lebanon from dealing directly or indirectly with unlicensed entities and listed Al-Qard Al-Hassan as an example. The bank had issued similar circulars in the past but this was the first time it mentioned Al-Qard Al-Hassan by name.

Rockets, rocket launchers and sniper rifles bound for Lebanon have been seized in Homs’ Qusayr region near the Lebanese border, the Syrian interior ministry said on Monday.

Syrian security forces in Homs had on August 19 seized a truck loaded with Grad-type rockets that was allegedly headed for Lebanon, Syrian state media reported at the time.
