(ANSA) Palermo, May 23 - Italian Education Minister Maria Chiara Carrozza was greeted by singing students when she arrived at the Sant'Agostino complex in the city of Corleone in Sicily to visit a photography exhibition marking the 21st anniversary of the slayings of anti-Mafia magistrates Giovanni Falcone and Paolo Borselllino. The exhibit, called Falcone and Borsellino 20 Years Later, is made up of photographs from ANSA, remembering the May 23, 1992 assassination of Falcone, his wife and three bodyguards when a bomb exploded on the Trapani-Palermo highway near Capaci in Sicily, and the assassination two months later of Borsellino in a car bomb attack in Palermo, which left five of his bodyguards dead and 20 people injured. The minister expressed great satisfaction for being able to visit the exhibition in a city once infamous as a breeding ground for Cosa Nostra. "Corleone today is a base for lawfulness, and these initiatives makes one feel that one is not isolated," said Mayor Lea Savona, who welcomed Carozza together with the head of the ANSA bureau in Palermo, Franco Nuccio, and Father Luigi Ciotti, who runs Libera, an organization that converts former mob property into socially responsible businesses and institutions. The exhibition includes historic photos of the Falcone and Borsellino families, as well as snapshots of anti-Mafia trials, and then also news photographs of the two killings in 1992.
