The attack by Jewish extremists on the King David Hotel is considered an act of terrorism for two reasons. First, because the target was largely of a civilian nature. The majority of the hotel was largely taken up by civilian administrative personnel; only a few offices had any military function. Second, because the perpetrators were a Jewish extremist group that committed atrocities throughout Palestine. They were referred to as terrorists by foreign organizations, the media of the day, and even by Jews themselves: "Leaders within the mainstream Jewish organizations, the Jewish Agency, Haganah and Histadrut, as well as the British authorities, routinely condemned Irgun operations as terrorism and branded it an illegal organization as a result of the group's attacks on civilian targets."
