"In my analysis, the situation is more complicated because of the internal political configuration on both sides. I am talking about Israel and Hamas," Mustafa Madbuli said at a seminar on Gaza at the special meeting of the World Economic Forum (WEF) held in Riyadh. The head of the Egyptian government -- a country that mediates between Israel and Hamas, along with Qatar and the United States -- assured that there is "a lot of internal pressure on both sides not to reach any kind of compromise." This pressure makes it "really difficult" to reach an agreement on a truce, because "the best and most correct solution, which is perhaps in the public interest, is not being sought." Regarding the resumption of negotiations encouraged by Egypt, Madbuli assured that "there is progress on certain issues, but there are still fundamental points on which there must be some kind of compromise by both parties in order to accept (an agreement), so that a solution can be reached." "That is what we are facing," said the head of the Egyptian government. Today, a Hamas delegation arrived in Cairo to hold "extensive talks" with Egyptian security agency officials on the latest proposal to achieve a ceasefire in the Gaza Strip, Egyptian state television Al-Qahera News reported. On the other hand, Madbuli insisted that "the most important thing is to work to avoid an attack on Rafah," a city in the southernmost part of Gaza that borders Egypt and where about 1.4 million people displaced by the war in the Palestinian enclave are currently living. An Israeli invasion of Rafah would be "catastrophic," according to the Egyptian prime minister, stressing that such an action could "pressure (the population of Gaza) to cross the border into Egypt." "Of course, as a government, we will be ready from a humanitarian point of view to provide any kind of support to the Palestinians. But if we talk about the political effects, this will contribute to the complete liquidation of the Palestinian cause," Madbuli warned. "All of this puts us, as an international society, in a situation where we have to do everything possible to avoid the invasion of Rafah and really pressure both sides to reach a ceasefire agreement and have at least a period in which negotiations can begin," he concluded.
