The Israeli and Palestinian leaders will hold a second summit within a week, Palestinian Foreign Minister Nabil Shaath announced. The meeting will follow up summit in Egypt, where Israeli Prime Minister Ariel Sharon and Palestinian leader Mahmoud Abbas announced an end to four years of hostilities. Abbas tried to nail down his pledge to stop attacks against Israel Wednesday, preparing for talks with Gaza-based militants and dispatching a top aide for a showdown with Hizbollah. Expressing satifaction with the summit's results, Abbas said Israel will lift travel restrictions on Palestinians in some parts of the West Bank and abandon several major checkpoints as part of its withdrawal from the towns of Jericho, Tulkarem, Qalqilya, Bethlehem and Ramallah in the next three weeks.
