adopted Resolution 340. This time the ceasefire held, and the fourth Arab–Israeli war was over. Disengagement agreement Disengagement talks took place on October 28, 1973, at "Kilometre 101" between Israeli Major General Aharon Yariv and Egyptian Major General Abdel Ghani el-Gamasy. Ultimately, Kissinger took the proposal to Sadat, who agreed. United Nations checkpoints were brought in to replace Israeli ones, nonmilitary supplies were allowed to pass, and prisoners-of-war were to be exchanged. A summit conference in Geneva followed in December 1973. All parties to the war—Israel, Syria, Jordan and Egypt—were invited to a joint effort by the Soviet Union and the United States to finally usher peace between the Arabs and Israelis. This conference was recognized by UN Security Council Resolution 344 and was based on the Resolution 338, calling for a "just and durable peace". Nevertheless, the conference was forced to adjourn on January 9, 1974, as Syria refused attendance. After the failed conference Henry Kissinger started conducting shuttle diplomacy, meeting with Israel and the Arab states directly. The first concrete result of this was the initial military disengagement agreement, signed by Israel and Egypt on January 18, 1974. The agreement commonly known as Sinai I had the official name of Sinai Separation of Forces Agreement. Under its terms, Israel agreed to pull back its forces from the areas West of Suez Canal, which it had occupied since the end of hostilities. Moreover, Israeli forces were also pulled back on the length of the whole front to create security zones for Egypt, UN and Israel, each roughly ten kilometres wide. Thus Israel gave up its advances reaching beyond the Suez canal, but it still held nearly all of Sinai. It became the first of many such Land for Peace agreements where Israel gave up territory in exchange for treaties. On the Syrian front, skirmishes and artillery exchanges continued taking place. Shuttle diplomacy by Henry Kissinger eventually produced a disengagement agreement on May 31, 1974, based on exchange of prisoners-of-war, Israeli withdrawal to the Purple Line and the establishment of a UN buffer zone. The agreement ended the skirmishes and exchanges of artillery fire that had occurred frequently along the Israeli-Syrian ceasefire line. The UN Disengagement and Observer Force (UNDOF) was established as a peacekeeping force in the Golan. The peace discussion at the end of the war was the first time that Arab and Israeli officials met for direct
