On 22 July 1946, Irgun bombed the British administrative headquarters for Palestine, which was housed in the southern wing of the King David Hotel in Jerusalem. A total of 91 people of various nationalities were killed and 46 were injured. The hotel was the site of the Secretariat of the Government of Palestine and the Headquarters of the British Armed Forces in Mandatory Palestine and Transjordan. The attack initially had the approval of the Haganah. It was conceived as a response to Operation Agatha (a series of widespread raids, including one on the Jewish Agency, conducted by the British authorities) and was the deadliest directed at the British during the Mandate era. The Jewish insurgency continued throughout the rest of 1946 and 1947 despite concerted efforts by the British military and Palestine Police Force to suppress it. British efforts to mediate a negotiated solution with Jewish and Arab representatives also failed as the Jews were unwilling to accept any solution that did not involve a Jewish state and suggested a partition of Palestine into Jewish and Arab states, while the Arabs were adamant that a Jewish state in any part of Palestine was unacceptable and that the only solution was a unified Palestine under Arab rule. In February 1947, the British referred the Palestine issue to the newly formed United Nations. On 15 May 1947, the General Assembly of the United Nations resolved that the United Nations Special Committee on Palestine be created "to prepare for consideration at the next regular session of the Assembly a report on the question of Palestine." In the Report of the Committee dated 3 September 1947 to the General Assembly, the majority of the Committee in Chapter VI proposed a plan to replace the British Mandate with "an independent Arab State, an independent Jewish State, and the City of Jerusalem ... the last to be under an International Trusteeship System." Meanwhile, the Jewish insurgency continued and peaked in July 1947, with a series of widespread guerrilla raids culminating in the sergeants affair. After three Irgun fighters had been sentenced to death for their role in the Acre Prison break, a May 1947 Irgun raid on Acre Prison in which 27 Irgun and Lehi militants were freed, the Irgun captured two British sergeants and held them hostage, threatening to kill them if the three men were executed. When the British carried out the executions, the Irgun responded by killing the two hostages and hanged their bodies from eucalyptus trees, booby-trapping one of them with a mine which injured a British officer as he cut the body down. The hangings caused widespread outrage in Britain and were a major factor in the consensus forming in Britain that it was time to evacuate Palestine.
