Palestinians on Thursday slammed US President Barack Obama's United Nations address a day earlier, calling it a display of US bias towards Israel.

Commentators, politicians and ordinary Palestinians alike said the US leader's speech to the General Assembly, just days before the Palestinians apply to become a UN member state, showed Washington was incapable of serving as a fair broker between Israel and the Palestinians.

Gaza's Hamas leaders said the address showed that the Palestinians and the Arab world should stop relying on Washington.

"Obama's speech reflects the American bias towards the Israeli occupation and it proves that the continuing Arab and Palestinian bet on the Americans is wrong," spokesman Sami Abu Zuhri told AFP.

"We call for the adoption of a national Palestinian strategy based on self reliance and the Arab and Muslim world in light of this American and Israeli arrogance."

Commentators in the three main Palestinian newspapers all took the same angry and and disappointed tone over Obama's remarks from the podium at the General Assembly.

"Obama's speech... was a disappointment to those who had been waiting for something new from him, provoking extreme outrage and anger," wrote Talal Okal in al-Ayyam newspaper.

"It also closed all the doors and windows left open by the Palestinian president to allow some movement."

Okal accused Obama of "deepening the bias towards Israel's narrative, positions and policies."

"He offered more than just a token of bias and love towards the Jews and Israel. What he offered in his speech goes so far as to show compliance with, and full acceptance of, the policies and narrative and desires of Israel," Okal wrote.

"He put the Jews and Israelis in the position of victims who are surrounded by hatred and wars against them by Arab countries, but this speech of his contained nothing of the suffering of the Palestinians."

Al-Ayyam newspaper also satirised Obama's speech with a cartoon showing him delivering his address from the podium with a speech bubble in the shape of a Star of David coming from his mouth.

Writing in Al-Quds, the biggest Palestinian newspaper, Arab Israeli parliamentarian Ahmed Tibi said Obama's speech had been easily outshone by a later speech by French President Nicholas Sarkozy.

Although the French leader failed to offer support for a Palestinian bid to obtain full state UN membership, he proposed the alternative of a UN status upgrade through the General Assembly, and made clear reference to Palestinian suffering, Tibi said.

"Unlike the speech given by French President Nicholas Sarkozy, who devoted his whole speech to the Palestinian issue and spoke positively about the rights of the Palestinian people, Obama's speech was biased towards the Israeli narrative," he wrote.

"And more than that, in the same speech in which Obama praised the uprisings and revolutions by the Arab people against tyranny and oppression, he declined to even mention Israel's occupation of Palestinian land."

On the street in east Jerusalem, there were similar murmurings of discontent.

"It wasn't a surprise really, Israel and America are one, and Obama for sure will support Israel against the Palestinians so he is re-elected in 2012," 22-year-old Shadi Elias told AFP.
