CAIRO, Aug. 3 (Xinhua) -- A senior official of the Cairo-based Arab League (AL) on Sunday urged the rival Palestinian movements Fatah and Hamas to end their conflicts in the Palestinian territories.

    The armed clashes "among brothers in the Palestinian territories" are unacceptable, AL Assistant Secretary General for Palestinian Affairs Mohammed Sobeih told reporters on Sunday.

    The tragedy in the Palestinian territories should end as soon as possible, said Sobeih.

    The two Palestinian factions have been exchanging arrests and crackdown since a bombing attack on July 25 in western Gaza City that killed five Hamas militants and a little girl.

    On Saturday, heavy fighting between Hamas and a clan loyal to Fatah movement left nine Palestinians killed and some 90 others wounded.

    Saying the pan-Arab bloc is outraged by the conflicts in the Palestinian territories, Sobeih warned of destructive consequence on the Palestinian issue.

    The AL official urged the two Palestinian groups to release all fighters "without any exception" and put an end to the armed clashes.

    The AL is contacting the concerned sides to end the tragic events and hopes an Egyptian-brokered inter-Palestinian dialogue would start to reach a strong Palestinian national unity, said Sobeih.
