Nazi bureaucrats exiled in Argentina, which helped them gain easy access to weapons, an advantage which put them apart from other political organizations. They were also engaged in racketeering, demanding a “revolutionary tax” from many Jewish shops in the Once (once means 'eleven') neighborhood of Buenos Aires, until the shops organized themselves to confront the MNT together. At first mainly engaged in street fights with other rival students’ organizations, in particular concerning the conflict between nonreligious and religious schooling, the MNT also engaged in antisemitic acts (such as vandalism in the Jewish cemetery of La Tablada in 1959, etc.). The MNT's antisemitism became even stronger after Adolf Eichmann's May 1960 kidnapping by Israel's intelligence agency, the Mossad, leading to a violent antisemitic campaign which lasted until 1964, when the MNT was almost completely dismantled. This led the Jewish association DAIA to pressure the government into taking actions against MNT. The peak was reached on August 17, 1960, when MNT members from Sarmiento National High School attacked Jewish pupils and injured a 15-year-old, Edgardo Trilnik, during the celebrations in honor of José de San Martín, Argentina's national hero in the war of independence. From then on, the MNT perpetrated acts of intimidation against the Jewish community, including bombing synagogues and other Jewish institutions and defacing the buildings with antisemitic graffiti. Following Eichmann's execution in 1962, the MNT launched 30 antisemitic attacks. On June 21, 1962, they kidnapped a 19-year-old Jewish girl, Graciela Sirota, tortured her, and scarred her with Swastika signs. In retaliation against this odious act, which raised public outrage, the DAIA on June 28, 1962, stopped all the activities of Jewish trade, supported by students (many high schools went on strike) and various political organizations, trade unions and intellectuals. These violent actions finally led the government to issue decree 3134/63 which prohibited, in 1963, any MNT or GRN activity. However, the influence of the secret services effectively nullified this decree. Some members of the MNRT became famous on August 29, 1963, by assaulting the Policlínico Bancario bank, stealing 14 million pesos (equivalent to 100,000 US dollars), a fortune at the time. Two employees were killed in the assault and three injured. This was the first armed political action carried on by an exclusively civil group in Argentina's history, making of the MNT-MNRT the "first urban guerrilla group in Argentina". However, the police finally tracked down the robbers and practically
