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.

Interior Minister Marwan Charbel revealed that investigations into the assassination of Internal Security Forces Intelligence Bureau chief Brigadier General Wissam al-Hasan is making “speedy progress”, revealing that they have reaching important information in the case, reported the pan-Arab daily Asharq al-Awsat on Tuesday.

Security information revealed that the owner of the stolen car that was booby-trapped in the bombing that killed Hasan on Friday has been identified.

Former prime minister Saad Hariri on Sunday received phone calls from U.S. Secretary of State Hillary Clinton, French Foreign Minister Laurent Fabius and U.N. chief Ban Ki-moon, who offered him condolences on the assassination of Maj. Gen. Wissam al-Hasan and his bodyguard Ahmed Suhyouni.

“During the phone calls, discussions also tackled the developments which Lebanon is witnessing after the heinous assassination. (Ex-)Premier Hariri stressed that the Lebanese people are staging a civil, democratic movement to overthrow the government of Premier Najib Miqati, adding that March 14 forces will boycott the government until it falls, as it is the product of the Syrian-Iranian axis and is working to achieve the interests and influence of this axis at the expense of the interests and security of Lebanon and its people,” Hariri's office said in a statement.

Several people were injured as security forces used tear gas on Sunday to repel demonstrators trying to storm the Grand Serail, the headquarters of the Lebanese government in downtown Beirut, amid calls for Prime Minister Najib Miqati to resign.

Following the funeral nearby of slain Maj. Gen. Wissam al-Hasan, chief of the Internal Security Forces' Intelligence Bureau, "young people headed towards the building in the city center, but security forces blocked them by firing into the air and using tear gas," a policeman on the scene told Agence France Presse.

Former Prime Minister Saad Hariri called on Saturday on the Lebanese to attend the funeral of Internal Security Forces Intelligence Bureau head Brigadier General Wissam al-Hasan en mass.

He stressed that the roads shouldn't be blocked to allow everyone to reach the Martyrs Square in downtown Beirut.

Former Prime Minister Saad Hariri on Friday accused Syrian President Bashar Assad of ordering the assassination of Brig. Gen. Wissam al-Hasan, chief of the Intelligence Bureau of the Internal Security Forces, condemning the deadly bombing that hit the Ashrafiyeh district in Beirut as a “cowardly terrorist attack against all of Lebanon and all the Lebanese people.”

“I accuse Bashar Hafez Assad of assassinating Brig. Gen. Wissam al-Hasan,” said Hariri.

Former prime minister Saad Hariri on Thursday noted that he had tasked MP Oqab Saqr with coordinating “humanitarian, political and media support” for the Syrian people, adding that he was not performing “a jihadist duty against the Syrian people.”

“In response to the defamation campaign against al-Mustaqbal Movement, accused by Hizbullah and its media outlets of engaging in the current conflict in Syria, and to the accusations against MP Oqab Saqr in particular, the Press Office of former Prime Minister Saad Hariri wants to clarify that … Saqr was assigned by Premier Saad Hariri to follow up on the situation in Syria and to coordinate with the political forces in the Syrian opposition regarding the media and political support of al-Mustaqbal Movement to the Syrian people," said a statement.

Lebanese Forces leader Samir Geagea indirectly admitted that the March 14 forces had committed a mistake by agreeing to maintaining Speaker Nabih Berri in his position after the camp won a majority in the 2009 parliamentary elections, reported al-Akhbar newspaper on Thursday.

He told the daily: “With all due respect to Berri, we can no longer tolerate him as parliament speaker. We must form a harmonious government just as the other camp did.”

The March 14 camp and Progressive Socialist Party leader MP Walid Jumblat are expected to resume contacts in a hope to reach an agreement over a proposal to adopt small-sized electoral districts during the 2013 parliamentary elections, reported An Nahar daily on Wednesday.

Sources from the camp told the daily that even though the MP is still opposed to the small-sized districts, he is open to dialogue that could introduce amendments to the electoral draft law proposed by the opposition.

Former PM Saad Hariri stressed on Saturday that “Lebanon is not an unmanned drone”, in reference to the acknowledgment of Hizbullah chief Sayyed Hassan Nasrallah that his party sent a sophisticated unmanned drone over Israel last week, the An Nahar daily said.

Hariri said: “Everyone must shoulder responsibility. They must understand that Lebanon is not an unmanned plane,” particularly under the current crucial regional circumstances, Hariri told the daily in an interview.
