Al-Mustaqbal bloc on Tuesday called on the Lebanese people to stand by President Michel Suleiman as “the head of the state entrusted with the constitution,” considering also that Hizbullah's chief “crushed the Lebanese people's hopes of calm and stability.”

"We praise Suleiman's stances that were manifested today in delivering a note to U.N. Special Coordinator for Lebanon Derek Plumbly regarding the Syrian attacks on the country,” a released statement said after the bloc's weekly meeting at the Center House.

Free Patriotic Movement leader MP Michel Aoun on Tuesday said Hizbullah intervened militarily in Syria after “gunmen” were brought into Lebanon, putting the blame on the March 14 camp and accusing it of creating a “vacuum” in Lebanon.

"We discussed the 'carnival of speeches' that is taking place today about Syria and Hizbullah, as if we have no other problems and as if we forgot the epoch that led us here," Aoun said, referring to the memo submitted by March 14 to President Michel Suleiman.

Lebanese Democratic Party leader MP Talal Arslan considered on Tuesday that accusing Hizbullah of of inciting sedition in Lebanon “is unjust and an infringement on the martyrs' blood.”

"Accusing Hizbullah's resistance of inciting strife in the country is unfair and an infringement on every honorable countryman and on the blood shed by the martyrs,” Arslan said in a statement.

Clashes erupted on Tuesday afternoon between supporters of Islamist cleric Sheikh Ahmed al-Asir and members of the Hizbullah-affiliated Resistance Brigades in the Sidon neighborhood of Abra, leaving at least one person dead and four others wounded.

Caretaker Premier Najib Miqati reiterated on Tuesday his appeal for the international community to cooperate with Lebanon in sharing the burden of the Syrian refugee influx.

During a conference held at the Grand Serail and attended by U.N. High Commissioner for Refugees Antonio Guterres, Miqati called for imposing certain standards on the refugees entering Lebanon.

Caretaker Foreign Minister Adnan Mansour and al-Mustaqbal MP Ahmed Fatfat engaged on Tuesday in a war of words a day after the lawmaker said in a statement that the “Lebanese state doesn't have a Foreign Minister but a conspirator.”

Mansour said in a statement issued by his press office that Fatfat's statement is part of a campaign that is “personally targeting” him, which will only “make him hold stronger onto the national and principles to confront hypocrites.”
