Notorious Sicilian Mafia boss Salvatore "Toto" Riina has died from cancer, Italian media reports say.
He was serving 26 life sentences and is believed to have ordered more than 150 murders.
Riina had been in a medically induced coma and his family had been given special permission to visit him in the prisoners' wing of the hospital in Parma.
The mobster's eldest son, Giovanni, is serving a life sentence in jail.
Riina was behind a series of mafia bombings in Rome, Milan and Florence in 1993, which left 10 people dead.
