Young people of the Akiva youth movement, who had undertaken the publication of an underground newsletter, "HeHaluc HaLohem" ("The Fighting Pioneer"), joined forces with other Zionists to form a local branch of the Jewish Fighting Organization (ŻOB, Polish: Żydowska Organizacja Bojowa), and organize resistance in the ghetto, supported by the Polish underground Armia Krajowa. The group carried out a variety of resistance activities including the bombing of the Cyganeria cafe – a gathering place of Nazi officers. Unlike in Warsaw, their efforts did not lead to a general uprising before the ghetto was liquidated.
