RAMALLAH, May 23 (Xinhua) -- Egypt will invite Palestinian specialized committees to Cairo this week to start drawing up a formula of a national agreement ending two years of schism, a Palestinian official said Saturday.

    The committees will be invited separately "to start formatting a final version of what was agreed upon in the previous rounds of the Cairo-hosted dialogue," said Ahmed Qurei, the head of president Mahmoud Abbas' Fatah delegation to the dialogue.

    Every committee is responsible to settle one of five problematic issues between Fatah and the Islamic Hamas movement: forming a unity government, reforming the Palestinian Liberation Organization (PLO), holding elections, reforming security services and achieving a national reconciliation.

    When the committees deliver their conclusions to the Egyptian mediators, the leaders of the different Palestinian groups will travel to Cairo on June 5 "to ratify the final wording of the agreement."

    From the previous rounds of talks, it was known that Hamas and Fatah failed to agree on forming a unity government but agreed on holding elections in January 2010 though they did not yet agree on the electoral law.

    The national dialogue was sought to restore political unity to the Palestinian territories and to overcome the aftermaths of Hamas's violent takeover of the Gaza Strip in June 2007.
