Venezuela’s prosecutors have summoned Juan Guaido over his role in the “attempted coup d’etat,” as well as in alleged assassination attempts. Guaido is the main figure in US-backed efforts to oust President Nicolas Maduro. The move was announced by Attorney General Tarek William Saab on Tuesday in a televised speech. The official described Guaido as “one of the main perpetrators” of a “new” attempted coup.
