"On the night of 16 April 1973, militants of Potere Operaio set fire to the house of Mario Mattei, "guilty" of being the secretary of the Italian Social Movement in the popular neighborhood of Primavalle in Rome.
Two of his sons lost their lives in the fire: Virgilio, aged 22 , and little Stefano, a child of just 10, survived in the flames. A terrible massacre, two innocent young lives shattered by political hatred." Prime Minister Giorgia Meloni wrote this on social media, underlining that "our task today is not to forget and to condemn without ambiguity the cruelty of that dramatic page in our history represented by the so-called years of lead. No more hatred and political violence".
