She was chosen, the report said, because her story is representative of the plight of the Palestinian people.On Wednesday, the US - which sees the unilateral UN move as undermining chances to revive peace negotiations with Israel - officially asked the Palestinian Authority to abandon its plan to ask the UN later this month to recognize a Palestinian state along the pre-1967 lines. The request was relayed to PA President Mahmoud Abbas by US Middle East envoy David Hale during a meeting in Ramallah, Palestinian officials said. The meeting was attended by senior White House official Dennis Ross and US Consul-General in Jerusalem, Daniel Rubenstien.The officials said that the US envoys did not carry any new proposals for reviving the peace process.Herb Keinon contributed to this report.
