After World War II, Britain found itself in intense conflict with the Jewish community over Jewish immigration limits, as well as continued conflict with the Arab community over limit levels. The Haganah joined Irgun and Lehi in an armed struggle against British rule. At the same time, hundreds of thousands of Jewish Holocaust survivors and refugees sought a new life far from their destroyed communities in Europe. The Yishuv attempted to bring these refugees to Palestine but many were turned away or rounded up and placed in detention camps in Atlit and Cyprus by the British. Escalating violence culminated with the 1946 King David Hotel bombing which Bruce Hoffman characterized as one of the "most lethal terrorist incidents of the twentieth century". In 1947, the British government announced it would withdraw from Mandatory Palestine, stating it was unable to arrive at a solution acceptable to both Arabs and Jews.
