UN Secretary General Ban Ki-moon has called for continuing dialogue among all parties and respect for the constitution and the laws of Lebanon. In a statement received by AIR in Dubai today, the spokesperson of UN chief has said that Mr. Moon has emphasized the importance of preserving calm in Lebanon and reiterates his full support for the work of the Special Tribunal for Lebanon. On Wednesday evening, the national unity government of Lebanon collapsed after 11 ministers of opposition Hezbollah and its allies resigned over the dispute regarding UN tribunal investigating former Prime Minister Rafik Hariri's murder. A UN backed tribunal investigating Saad Haririri’s father Rafiq Hariri's killing is widely expected to name members of the Hezbollah in upcoming indictments, which many fear could re-ignite hostilities between Lebanon's rival Shiite and Sunni Muslims. Violence has been a major concern as tensions rise in Lebanon, where Shiites, Sunnis and Christians each make up about a third of the country's people. In 2008, sectarian clashes killed 81 people and nearly plunged Lebanon into another civil war. US Secretary of State Hillary Clinton said that Hizbullah's move was designed to subvert justice and undermine stability, stressing that it will not work.
