Egyptian President Hosni Mubarak on Saturday said the stalled Mideast peace process depended on the release of an IDF solider captured by terrorists in Gaza and resolving the violent conflict between rival Palestinian factions. Mubarak said Egypt was working to "seal the crack" between Hamas and Fatah who have been fighting for control of the Palestinian government since Hamas ousted its rival from power last year. But the Egyptian leader stressed that a deal also must be brokered to secure the release of Cpl. Gilad Shalit, who was captured by Palestinians in June. "It all depends on the soldier that was detained by the Palestinians, and at the same time the Palestinians are demanding the release of their detainees. We are working on this line, and we hope that we reach a solution soon," Mubarak said during a joint press conference with visiting German Chancellor Angel Merkel.
