Palestinian politicians rebuffed on Thursday a hard-fought blueprint for resumed talks with the Zionist entity thrashed out by US Secretary of State John Kerry in a blow to his marathon "peace efforts."

A US official had warned that Kerry was unlikely to be able to announce any breakthrough on resuming direct peace negotiations with the Palestinians despite extending until Friday his sixth visit to the region in as many months.

The setback for the US plan came from the governing Revolutionary Council of Abbas's own Fatah movement, which demanded changes.

Palestinian member of parliament Mustafa Barghuti said that "most factions" within the Palestine Liberation Organisation had rejected Kerry's proposal.

"During the leadership meeting, most of the Palestinian factions rejected restarting peace talks based on Kerry's proposals," he said.

A senior Fatah official said the party wanted changes to what Abbas had agreed.

"Fatah wants to make some alterations to Kerry's plan because the proposed ideas are not encouraging for a return to negotiations," the official added.

The announcement came after two rounds of intensive talks between Kerry and Abbas, who is also Fatah leader.

It was the top US diplomat's sixth visit to the region since he took office in February to try to resume "peace talks" between the Palestinians and the Zionists, who are outraged by the new EU guidelines that ban funding the Israeli settlements in the WB and East Jerusalem.
