Palestinian group Hamas is open to Arab mediation in its dispute with Fatah faction of President Mahmoud Abbas, the Arab League chief said in remarks published on Sunday. Amr Moussa said Hamas leader Khaled Meshaal expressed the Islamist group's view during a telephone conversation to congratulate him for achieving rapprochement between Lebanese factions, Asharq al-Awsat reported. "Brother Khaled Meshaal spoke with me ... expressing willingness for a process of the same nature to end the dispute between Fatah and Hamas," Moussa was quoted as saying in the newspaper report carried by Reuters. Qatar, spearheading an Arab League initiative, brokered a deal between Lebanese leaders last week defusing 18 months of political stalemate.
