He was one of the planners of the assassination of Lord Moyne . He saw the struggle against the British in an international context , and advocated collaboration with other anti-colonialist forces , including Palestinian and other Arab forces . After the Deir Yassin massacre , he privately confronted Eldad . After the assassination in September 1948 of United Nations mediator Count Folke Bernadotte , he was arrested along with Lehi member Matityahu Shmuelevitch and charged with leadership of a terrorist organization . They were found guilty on January 25 , 1949 , the day on which Yellin-Mor was elected to the Knesset . On February 10 , 1949 , Yellin-Mor was sentenced to 8 years imprisonment . Though the court was confident that Lehi was responsible for Bernadotte 's death , it did not find sufficient evidence that the murder had been sanctioned by the Lehi leadership . The court offered to release the defendants if they agreed to certain conditions that included forswearing underground activity and submitting to police supervision , but they rejected the offer . However the Provisional State Council soon authorised their pardon
