Banna wrote a pamphlet in which he rejected all the charges against the Brotherhood and condemned once again the acts of violence committed by its members, including the attacks on Jews; he said the Society's leaders would never have condoned this violence, and had been unable to prevent it because arrests and surveillance had made it impossible for them to exercise their authority. Nevertheless, he argued that these events were, in part, a result of the government's behaviour and the war in Palestine. He denied that the Society had been planning revolution, insisting that its arms had been intended for use only in Palestine in its legitimate partnership with the Arab League. In February 1949, Banna was assassinated by the political police, probably on the orders of the prime minister and the palace.
