On 2 August, a bomb killed 85 people and wounded more than 200 in Bologna. Known as the Bologna massacre, the blast destroyed a large portion of the city's railway station. This was found to be a neo-fascist bombing, mainly organized by the "Nuclei Armati Rivoluzionari": Francesca Mambro and Valerio Fioravanti were sentenced to life imprisonment. In April 2007 the Supreme Court confirmed the conviction of Luigi Ciavardini, a NAR member associated closely with close ties to "Terza Posizione". Ciavardini received a 30-year prison sentence for his role in the attack.
