Phalange Party leader Amin Gemayel urged on Monday Hizbullah to end its fighting in Syria and “return to the Lebanese fold,” while saying that he is not opposed to extending the term of Army Commander General Jean Qahwaji.

State Commissioner to the Military Court Judge Saqr Saqr has asked for the DNA samples of Sheikh Ahmed al-Asir's mother and the brother of singer-turned Salafist Fadel Shaker, the state-run National News Agency reported on Monday.

Caretaker Defense Minister Fayez Ghosn warned on Monday from the proliferation of extremists in Lebanon, accusing Lebanese political factions of playing a role in the rise of Salafist cleric Sheikh Ahmed al-Asir.

Some “Lebanese factions protected him all this time. Had the army arrested him, they would have said that a certain party is being targeted” through this arrest, Ghosn told al-Akhbar newspaper.

Caretaker Prime Minister Najib Miqati stressed on Monday that he rejected a parliamentary session that does not include essential items on its agenda but he also refused signing a decree that calls for an extraordinary session.

“I will not sign a decree for an extraordinary session. We don't want more problems,” Miqati said after talks with Speaker Nabih Berri in parliament.
