About 600,000 Palestinian (other estimates range form 500,000 to 800,0000) fled Israel between 1947 and 1949, fundamentally because of the Arab states' rejection of the United Nation partition plan and invasion of Israel. The refugees fled out of fear of war and in response to Arab leaders' calls for Arabs to evacuate the areas allocated to the Jews until Israel had been eliminated. In a handful of cases, Palestinians were expelled. A majority of the refugees and their descendants now live in the Gaza Strip, the Golan Heights and the West Bank. About 360,000 Palestinians fled eastern Jerusalem, the West Bank, the Gaza Strip and the Golan Heights during and after Israel's defensive 1967 War. Palestinian who fled in 1967 are technically considered displaced persons and do not have official refugee status. The United Nations Relief and Works Agency estimated that 175,000 of these 360,000 Palestinians were refugees from the 1948 War. The May 4, 1994, Gaza-Jericho Accord calls for Israel, the Palestinians, Jordan, and Egypt to form a Continuing Committee to discuss the 1967 displaced persons. The problem of the 1947-1949 refugees, on the other hand, is to be left for the “final status” negotiations under the terms of the Israeli-PLO Declaration of Principles of September 13, 1993.
