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.
