Palestinian Authority Prime Minister Salaam Fayad warned Friday that peace talks could collapse unless Israel changes course and accepts a more conciliatory approach. Fayyad, who was in London for diplomatic talks, said Israel has not complied with any of the obligations set out at the Annapolis peace conference in November. "Israel has failed to meet any of its obligations from the 'road map,' including a freeze in settlement activity," he said. "That is most troubling. Unless that changes, the political process is being stripped of its meaning." Fayyad said the Palestinian government has met its commitments.
