In 1937 the Jewish Agency's intelligence groups were responsible for bugging the Peel Commission hearings in Palestine. Eventually, the Arab Revolt convinced the Agency that a central intelligence service was required and this led to the formation of a counter-intelligence agency known as the "Ran" (headed by Yehuda Arazi, who also helped to smuggle rifles, machine guns and ammunition from Poland to Palestine) and thereafter in 1940 to the creation of SHAI, the forerunner of Mossad.
