Quds city, Feb 21, SPA -- Israel freed 500 Palestinian prisoners in a good-will gesture Monday, a day after the government gave final approval to a pullout from Gaza and a revised route of the West Bank separation barrier that would encompass at least 6 percent of land claimed by the Palestinians for a future state. With the historic Cabinet vote, Israel began charting its final borders, bypassing negotiations and angering the Palestinians. Prime Minister Ariel Sharon said the decision to leave Gaza and four settlements in the northern West Bank was the hardest he ever made, but would ensure a better future for Israel. Sharon signed an order saying Israeli civilians would have to leave the areas slated for evacuation by July 20. Those remaining would be removed by force over a period of two months. Settler leaders have pledged not to leave voluntarily, and security officials are bracing for violent confrontations.
