The Arab League chief on Wednesday urged Lebanon's feuding leaders to break a political impasse that has paralyzed the country and warned that "time is running out." Amr Moussa began Tuesday a three-day visit here, in an attempt to help politicians end the monthslong crisis between the Western-backed government and the Syrian-supported opposition led by Hizbullah. Lebanon has been going through its worst political crisis since the end of the 1975-1990 civil war. Parliament is not functioning and the government just barely, after a quarter of Cabinet members resigned. Another crisis is looming over the presidency - the legislature must vote on a replacement when President Emile Lahoud's term ends in November, but it is highly unlikely that lawmakers will be able to agree on a candidate, in turn leading to a power vacuum.
