RAMALLAH (AFP) - Palestinian leader Mahmud Abbas revealed he held four secret meetings with Israeli President Shimon Peres in a bid to revive stalled peace talks, a Palestinian official said Saturday. He quoted Abbas as saying at a meeting of his Fatah party on Friday that: "I met Shimon Peres four times in Amman and London in an attempt to restart negotiations and the peace process on a correct foundation." The official, speaking on condition of anonymity, added that Israel's Prime Minister Benjamin Netanyahu had thwarted those efforts. "Shimon Peres assured me that the negotiations between us could lead to results that could be adopted by the Netanyahu government," the official quoted Abbas as saying. "After the first four meetings, a fifth was scheduled in Amman, but Shimon Peres apologised and said, 'I'm sorry but the government does not accept that we negotiate and I cannot do anything,'" Abbas said at the Friday gathering, according to the official. Meanwhile, the Palestinians are to present their bid for United Nations membership on September 20, Palestinian foreign minister Riyad al-Malki told AFP on Saturday. "Palestinian president Mahmud Abbas will personally present the request to UN Secretary General Ban Ki-moon... at the opening of the sixty-sixth session," on September 20, Malki said.
