On this day in 1963 the Ciaculli Massacre took place. The event started with a car bomb that exploded in Ciaculli, an outlying suburb of Palermo. The bomb killed seven police and military officers that were sent out to defuse it after an anonymous phone call. The bomb was intended for Salvatore Greco, who was the head of the Sicilian Mafia Commission and the boss of the Ciaculli Mafia family.

Mafia boss Pietro Torretta was considered to be the man behind the bomb attack.
