The first deaths of the war occurred on 30 November 1947: Two busses carrying Jews were ambushed. There had been tension and conflict between the Arabs and the Jews since the 1917 Balfour Declaration and the 1920 creation of the British Mandate of Palestine. Neither the Arabs nor the Jews liked British policies. The Arabs' opposition developed into the 1936–1939 Arab revolt in Palestine. The Jewish resistance developed into the Jewish insurgency in Palestine (1944–1947). In 1947, these tensions led to civil war . The United Nations Partition Plan for Palestine was adopted on 29 November 1947: it planned to divide Palestine into an Arab state, a Jewish state, and the Special International Regime for the cities of Jerusalem and Bethlehem.
