Lebanese Forces leader Samir Geagea on Tuesday warned that “the killing machine has returned and we must find a solution to stop it," in the wake of the assassination of Intelligence Bureau chief Maj. Gen. Wissam al-Hasan in a car bombing blamed on Syria.

"The current situation is unacceptable as we are being killed," Geagea said at a press conference in Maarab, adding that "the parliamentary political life in Lebanon is not normal."

Al-Mustaqbal parliamentary bloc on Tuesday called for forming "a neutral salvation government comprising members from outside the March 14 and March 8 camps," while announcing that it will boycott any national dialogue session or parliamentary meetings that involve the participation of the government.

“This new government must shift the country from the state of tension to a state of calm, security and stability, which would represent the first step towards restoring balance and national partnership in Lebanon,” the bloc said.

The Army Command on Tuesday announced that army units arrested around 100 gunmen, including 34 Syrians and four Palestinians, in a security sweep in Beirut and Tripoli, as calm returned to the areas that witnessed deadly clashes over the past three days.

“Army units deployed in the areas that witnessed unrest over the past few days continued implementing the security plan laid out by the Command to suppress the presence of gunmen on the streets and confront any shooting, rioting or attacks against citizens' properties,” the Army Command said in a statement.

Free Patriotic Movement leader MP Michel Aoun on Tuesday reiterated his condemnation of the assassination of Intelligence Bureau chief Maj. Gen. Wissam al-Hasan, but stressed that “political accusation” must stop.

“Accusations must stop because there is nothing called 'political accusation,' which is something outrageous,” Aoun said after the weekly meeting of the Change and Reform bloc, referring to the March 14's camp accusation that the Syrian regime was behind the crime.

South Lebanon Prosecutor Judge Samih al-Hajj on Tuesday filed a lawsuit against persons unknown on charges of trying to assassinate Free Patriotic Movement leader MP Michel Aoun in the coastal city of Sidon in September.

Media reports said Aoun's convoy came under gunfire in Sidon on September 22 while he was returning from Jezzine.

Prime Minister Najib Miqati on Tuesday stressed that he is doing what his conscience obligates him to do – “protecting Lebanon from political vacuum and divisions,” amid calls by the March 14 forces for him to resign.

“With my arrival in the holy city of Medina, I will start praying to God Almighty to protect Lebanon and the Lebanese from any evil,” Miqati said on the social networking website Twitter, after he arrived in Saudi Arabia to perform the hajj pilgrimage.

More than 100,000 Syrians have fled their war-torn country for neighboring Lebanon, itself hit by rising tensions in recent days, the U.N. refugee agency said Tuesday.

"Lebanon has become the third country in the region to see its population of registered Syrian refugees and people waiting for registration (exceed) the 100,000 mark," the UNHCR said in a statement.

President Michel Suleiman voiced on Tuesday his support for the army's efforts to maintain peace and stability in Lebanon.

He said after meeting Defense Minister Fayez Ghosn: “The army's measures to preserve security have demonstrated that the state and all of its institutions are the only safe haven for all the Lebanese people.”

President Michel Suleiman held a series of consultations on Tuesday with Lebanese foes over the political situation in the country while the opposition insists on the resignation of the cabinet as a key condition to resume any political activity with the March 8 alliance.

Head of al-Mustaqbal parliamentary bloc MP Fouad Saniora held talks with Suleiman at the Baabda Palace, where he briefed him on the March 14 alliance's demands concerning the immediate resignation of the government and the camp's stance from the recent developments in the country.

March 14 camp MP Ammar Houri revealed that he and four colleagues were texted death threats from a Syrian telephone number before and after Internal Security Forces Intelligence Bureau head Wissam al-Hasan's assassination on Friday.

"On the eve of the attack, we received an SMS from a Syrian number that read: 'Sons of bitches, we will get you one by one,'" Ammar Houri said on television on Monday night.
