Jerusalem ? Israel completed the release of 86 Palestinian prisoners on Tuesday, a gesture meant to improve prospects for a U.S.-sponsored Mideast peace conference later this fall.

The prisoner release came a day before Israeli Prime Minister Ehud Olmert and Palestinian President Mahmoud Abbas were to begin working out their joint vision of a peace deal at a meeting in Jerusalem. They hope to present a framework agreement to the international community at the November summit.

Israel sent 29 Palestinians back to the Gaza Strip on Tuesday, following the release of 57 prisoners in the West Bank a day earlier.
