Some former Zionists had by then joined the Communist Party. In 1950, they were singled out among the 5.6% undesirables whom the party wanted purged from its ranks. The same year saw mass arrests of Zionist militants, followed by their torturing and nine separate waves of show trials, lasting to 1959. The first such group, comprising Revisionists Șlomo Șinovitzer, Marcel Tăbăcaru and Pascu Schechter, was sentenced in July 1953. Another trial staged in 1954 for thirteen Zionist leaders, including Zissu, Benvenisti, and Moscovici. Meanwhile, Marton, praised for his humanitarian work with deportees regaining republican Hungary, began putting out a new edition of "Új Kelet" from his new home in Palestine.
