MLN-T began by staging the robbing of banks, gun clubs and other businesses in the early 1960s, then distributing stolen food and money among the poor in Montevideo. By the late 1960s, it was engaged in political kidnappings, armed propaganda and assassinations. The group kidnapped bank manager Pereyra Rebervel and the United Kingdom ambassador to Uruguay, Geoffrey Jackson, as well as kidnapping and murdering Dan Mitrione, an FBI agent alleged to have taught techniques of torture to police forces in various Latin American countries.
