Arabs say 'no' to Israeli border plan

"The result was expected. But what is more important now is that Olmert changes his agenda and abandon his unilateral plans to fix the borders," Abbas told reporters on the sidelines of an Arab summit in Khartoum.

The double whammy of Olmert's victory and international threats to isolate the Palestinians' new Hamas-led government has left the Arab world grappling for the proper response to the challenging new realities.

The Arab summit quickly adopted a resolution in reaction to Olmert's victory, which paved the way for his centrist Kadima party to implement its groundbreaking pledge to fix the Jewish state's boundaries by 2010.

The leaders endorsed a statement calling for the rejection of "Israeli measures including... fixing Israel's borders unilaterally in a way that fulfils its expansionist greed."

The resolution said such actions by Israel "render impossible the establishment of an independent and sovereign Palestinian state."

The summit had already urged the international community not to punish the Palestinians for voting the Islamic radical movement Hamas into power in January in an upset victory over Abbas's mainstream Fatah party.

"All calls to distort the political meaning of the Palestinian choice by threatening to boycott it and cut aid cannot be justified," Algerian President Abdelaziz Bouteflika told the summit, which itself has been marred by poor attendance and the absence of key regional leaders.
