An Arab political source said Friday that special U.S. Mideast envoy George Mitchell has requested to resign due to his frustration with the way the Obama administration has been handling the Israeli-Palestinian conflict, according to a Nazareth-based daily.

Hadith a-Nass reported that Mitchell's request stemmed partly from to his own failure to advance the resumption of peace negotiations between Israel and the Palestinians and also from his perception that certain elements within the State Department hold biased favor toward Israel.

The White House turned down Mitchell's request, according to Hadith a-Nass.

No verification of the report was available.

Peace talks were halted more than a year ago over the war in the Gaza Strip and have not resumed, due largely to a Palestinian demand that Israel first impose a complete freeze on building in the West Bank and East Jerusalem and Israel's refusal to do so.

A new working paper released by the Palestinian indicates that the Palestinian Authority has warned it may abandon its support of the 1993 Oslo Accords, which outlines a two-state solution to the conflict with Israel.

The Palestinians are instead intending to pursue the creation of a binational state between the Jordan River and Mediterranean Sea, according to a document drafted by the PA's veteran chief negotiator.
