Arab League Secretary General, Amr Mussa Has Expressed Deep Regret Over The Tragic Developments Emerging On The Palestinian Arena, Including The Prevailing Chaos And Major Sides Retreating From Forming A National Unity Government. Internal Conflicts Are The Worst Of What Could Happen In Palestine For Their Negative Impact On The Credibility Of The Palestinian Cause, Mussa Said In A Statement To Journalists On Monday. He Warned That Fighting Among Palestinian Factions Would Generate More Wrath And Underlined The Need For Agreeing On A National Unity Government To Avert Such Hazards. If Such A Government Is Not To See Life And The Arab Peace Initiative Is Not To Be Endorsed, The Palestinian Cause Will Remain At Windward, Mussa Wondered.
