One year later ( May – July 1993 ) , after the arrest of mob boss Salvatore Riina , the Mafia furthered their campaign of terrorism on the Italian mainland . Tourist spots were attacked , such as the Via dei Georgofili in Florence , Via Palestro in Milan , and the Piazza San Giovanni in Laterano and Via San Teodoro in Rome , leaving 10 dead and 93 injured and causing severe damage to cultural heritage such as the Uffizi Gallery . The Catholic Church openly condemned the Mafia , and two churches were bombed and an anti-Mafia priest shot dead in Rome
