RIYADH (AFP) - Saudi King Abdullah has told Palestinian President Mahmud Abbas that the split within the Palestinians ranks is more damaging to their cause of an independent state than the Israeli enemy. In a letter to Abbas marking his Fatah partys first congress in 20 years, the Saudi King stressed that all Palestinian factions need to come together to make an independent Palestinian state possible. The arrogant and criminal enemy was not able, during years of continued aggression, to hurt the Palestinian cause as much as the Palestinians hurt their cause themselves in the past few months, Abdullah said in the letter released through the official SPA news agency late Tuesday. I can honestly tell you, brothers, that even if the whole world joins to found a Palestinian independent state, and if we have full support for that, this state would not be established as long as the Palestinians are divided. This letter from the holy land does not represent my sentiments alone but the sentiments of one thousand million Arabs and Muslims who see their greatest issue is the Palestinian issue. In Bethlehem, the second day of Fatahs first congress in 20 years was marked by acrimonious rows on Wednesday as delegates demanded accountability from the leadership of Palestinian President Mahmud Abbass party. Hundreds of delegates at the gathering in the West Bank city of Bethlehem protested the lack of administrative and financial accounting by the Fatah leadership since the last congress in 1989. They rejected the explanations of the partys governing bodies that Abbas opening speech on Monday amounted to a report on Fatahs management over the past 20 years. Delegates interrupted a speech by central committee number two Ahmed Ghneim, who angrily left the podium. Abbas, who did not take part in the debates, was called into the hall to help calm things down. I admit we have committed errors, even sins, but the rendering of accounts must be done during committee meetings and not through chaotic interventions, he said. But Abbas himself was interrupted. Security forces briefly intervened as a delegate ordered out by Abbas refused to leave the room. We are here to put Fatah back on track, not to settle scores, Abbas said. Fatah, which is at the helm of the Palestinian Authority, exercised undivided power among Palestinians before it was trounced by the rival Islamist Hamas movement in a 2006 parliamentary election. Longstanding Hamas-Fatah tensions boiled over in June 2007 when the movement seized control of Gaza after a week of deadly street clashes, confining Abbas power base to the Israeli-occupied West Bank. Infighting and corruption allegations have helped weaken the dominant position in Palestinian political life that Fatah enjoyed before the 2004 death of its founder and iconic leader Yasser Arafat. In his opening speech, Abbas listed a litany of errors he said Fatah had committed but urged delegates to learn from them and use the congress as a platform to give Fatah a new start. The meeting is scheduled to conclude on Thursday (today) but could last another day or two because of disagreements between delegates and the leadership over the agenda. Meanwhile Fatah members in the Gaza Strip who were prevented by Hamas from leaving the enclave to attend the congress, demanded that they be allocated a quota of positions in the partys governing bodies - the Central Committee and the Revolutionary Council. Gaza will have adequate representation, congress spokesman Nabil Amr said, avoiding using the word quota. The congress is due to adopt a new political programme and replace some of the top leaders of Fatah. It is only the sixth such conference since the party was founded by Arafat in the late 1950s.
