 Known as the Bologna massacre, the blast destroyed a large portion of the city's railway station.This was found to be a fascist bombing, mainly organized by the NAR, who had ties with the Roman criminal organization "Banda della Magliana".In the following days the central square of Bologna, Piazza Maggiore, hosted large-scale demonstrations of indignation and protest among the population, in which were not spared harsh criticism and protests addressed to government representatives, who attended the funerals of the victims celebrated in the San Petronio Basilica on 6 August.
