Investigators probing the roadside bombing that targeted a U.N. convoy on Tuesday have said that the bomb weighed around 6 kilograms and was detonated through an electric wire.

Security sources told Beirut dailies that the 6-kilogram TNT was hidden under dirt on the side of the road near the southern port city of Sidon when it was detonated, injuring six French peacekeepers.

Progressive Socialist Party leader MP Walid Jumblat expressed fear on Thursday that targeting the United Nations Interim Force in Lebanon (UNIFIL) will cause a major vacuum in the south which will benefit Israel and endanger Lebanon.

Jumblat told As Safir newspaper that the attack on the UNIFIL is “suspicious” and it might be intended to cause vacuum in the south, which will lead to a minimized presence for these forces in the area.

UNIFIL Commander Major-General Alberto Asarta Cuevas has said investigators trying to determine who was responsible for a roadside bomb that injured six French peacekeepers have "a lot of evidence" that will hopefully lead to the perpetrators.

Speaking in New York, Asarta wouldn't speculate on who set off Tuesday's bomb near the southern port city of Sidon as a four-vehicle U.N. convoy was passing by.

President Michel Suleiman’s attempt to come up with an agenda for the national dialogue is becoming complicated as he moves to his summer residence in Beiteddine next week and as both the March 8 and 14 forces hold onto their stances.

Informed sources ruled out that Suleiman could put the agenda of the dialogue that he intends to hold during Ramadan. The president will move to Beiteddine on August 3 and will hold consultations there during his three-week stay to mull the viewpoints of political leaders on his invitation for dialogue, the sources told An Nahar daily.

Phalange Party leader Amin Gemayel on Wednesday stressed that “land is as important as dignity and sovereignty,” warning that “persistence in the seizure of others’ property” might lead to “civil strife.”

Maronite “Patriarch Beshara al-Rahi has made a lauded initiative and we support him in his bid to solve the dispute over land owned by the church,” Gemayel said during a visit to the Jbeil District town of al-Ghabat, which borders the predominantly Shiite town of Lassa – the scene of recent controversy over property rights between locals and the Maronite Patriarchate.

Speaker Nabih Berri renewed on Wednesday the importance of dialogue in Lebanon, especially under the current circumstances in the region.

He said before MPs during his weekly meeting at parliament: “Lebanon is not isolated from the rest of the region and we should not hesitate in implementing any step that would help fortify it.”

Lebanese Forces leader Samir Geagea condemned on Wednesday the attacks against the French unit in the United Nations Interim Force in Lebanon that took place near Sidon on Tuesday, thanking the French government for all its support for Lebanon.

He noted: “The security situation can never turn to normal as long as there are hundreds of thousands of unofficial security apparatuses.”
