SHARM EL-SHEIKH, Egypt (AFP) - European and Middle East leaders on Sunday stepped up the pressure on Israel to withdraw all its troops from the Gaza Strip and announced plans for an international aid conference. Egypt will host an international meeting to "muster the necessary resources to rebuild Gaza," Mubarak told journalists after a summit of European and Arab leaders in the Red Sea resort of Sharm el-Sheikh. In the Gaza summit, the leaders, as well as UN Secretary General Ban Ki-moon and including Palestinian President Mahmud Abbas, also issued a rallying call to the world to support the fragile truce between Israel and Hamas militants. French President Nicolas Sarkozy, who co-chaired the summit with Egyptian counterpart Hosni Mubarak, said Israel should pull out its forces from the Gaza Strip if Palestinian fighters stop firing rockets at the Jewish state. Alongside five other European leaders in the Red Sea resort of Sharm el-Sheikh, Sarkozy said: "Israel must indicate clearly that if the rocket firing stops, the Israeli army will leave Gaza." British Prime Minister Gordon Brown went further, saying Israeli soldiers must withdraw immediately, but also called on Hamas to end the rocket attacks, which sparked the three-week war. "This fragile ceasefire has got to be followed immediately, if it is to be sustainable, by humanitarian access... by troop withdrawals, by an end to arms trafficking," Brown told journalists. "Today a humanitarian tragedy must be met not just by sympathy but by an immediate mobilisation of aid," he said. The summit looked to bolster the response of the international community which has already seen pledges from Germany and the United States, among others, to help seal off the tunnels on the Egypt-Gaza border that are a lifeline of the Hamas fighters and Gaza's residents. Abbas, who held meetings early Sunday with Mubarak in Cairo, said now that the fighting had stopped a major effort must be launched right away. "We wished from the first day that this aggression did not happen, but when it started our first demand was the end of the aggression. "And now it has stopped we wish the end to the aggression remains, and that humanitarian aid begins (reaching) our people immediately." The summit attendees in Sharm el-Sheikh thanked Mubarak for Egypt's efforts in breaking the deadlock. Egyptian officials held talks with a Hamas delegation in Cairo earlier in the day aimed at consolidating the ceasefire. "We are working with Hamas, and discussions were held today with them. As soon as Hamas's position is clarified we will let Israel know and wait for them to come," foreign ministry spokesman Hossam Zaki told AFP. Nabil Amro, Abbas's ambassador in Egypt, said earlier that the Palestinian Authority insists on the deployment of international troops to Gaza to "protect the Palestinian people." After the summit, the six European leaders attending " Sarkozy, Brown, and the leaders of Germany, Spain, Italy and the Czech Republic " headed to Israel for dinner talks with Olmert. Meanwhile, Egypt President Hosni Mubarak, Jordanian King Abdullah II and Arab League chief Amr Mussa called for an end to the Arab-Israeli conflict in 2009, at the end of a summit in Egypt Sunday. "I hope that 2009 will be the year that will see the end of all these conflicts," Mubarak said, "adding my voice" to Abdullah's and Mussa's at the end of the meeting. Meanwhile, Pope Benedict XVI on Sunday backed the latest efforts to end the violence in the Gaza Strip and offered prayers for the innocent victims of the conflict. The pope called for support for all those trying to "stop the tragedy" in the Gaza Strip, just hours ahead of a summit on the crisis in Egypt. He lent his support to "those who, on one side and the other, believe that there is a place for everyone in the Holy Land." The pontiff also expressed his wish that they could "help their populations pick themselves up from the ruins and the terror and courageously pick up again the thread of dialogue, in justice and in truth." Speaking during the traditional Angelus prayers at the Vatican, he also prayed for the hundreds of children, elderly people, women: "innocent victims of an unheard of violence."
