A terrorist group called the Zarate Willka Armed Forces of Liberation (Fuerzas Armadas de Liberación Zárate Willka—FALZW), presumably another name for the FIPZW, took responsibility for a bombing in December 1988 that caused much damage to the offices of the president of the Chamber of Deputies and for machine gunning to death two young Mormon missionaries from Utah in a La Paz barrio in May 1989. Pre-election terrorism by unknown perpetrators in March 1989 included bombings at various political party offices in the La Paz area that caused considerable property damage and a bomb attempt at the United States embassy.
