RAMALLAH (AFP) - The Palestinians are planing to ask the United Nations to recognise a Palestinian state and grant them membership of the world body, a top official said Sunday. The decision to go forward with the plan had been made by the Palestinian leadership and it is the "choice of president Mahmud Abbas," chief Palestinian negotiator Saeb Erakat told AFP. However, Erakat said no date had been set for the move, which would request the world body recognise a Palestinian state within the 1967 borders and with east Jerusalem as its capital, saying only that it would happen "as soon as possible." It comes after the United States in February vetoed a Security Council resolution that would have condemned continued Israeli settlement building. The resolution, drafted by the Palestinian leadership in an attempt to pressure Israel to halt settlement construction in the West Bank and east Jerusalem, was supported by the 14 other members of the Security Council.
