An 18-month-old boy was mauled to death by two Argentinian Mastiff dogs in Mascalucia near Catania, earlier today, Ansa news agency reported.
The boy's mother, who tried to protect her son, was injured.
The toddler was flown to hospital by helicopter but was pronounced dead on arrival. The dogs have been impounded by the authorities.
The mother, 34, who was alone with her son when the dogs attacked, has been placed under investigation in what police said was a formality needed for the autopsy.
Another tragedy in the UK
Meanwhile, a 52-year-old man died in the UK after being attacked by a dog which had been returned to its owner despite concerns that it was dangerous.
West Yorkshire Police said David Ellam was out walking with his Yorkshire terrier in Huddersfield when he was attacked by another dog. He died later in hospital.
The incident has been referred to the Independent Police Complaints Commission (IPCC) because the dog involved in the attack was seized by officers earlier this month but returned to its owner a week ago after it was determined it was not a banned breed.
A woman who said she was Mr Ellam's cousin wrote on Facebook: "There was nothing accidental about this, it was a tragic incident that should never have happened and correct measures were not taken to ensure this situation wouldn't arise.
"We hope that in the coming days, a true representation of what happened yesterday will come to light and end all speculation. At this point, there is nothing to gain from finger pointing or blaming of dangerous dogs or their owners - a man has died in one of the most horrific ways possible, and we should focus on making sure this never happens again rather than playing the blame game."
A 29-year-old man, the owner of the dog, was arrested in connection with the incident and later released on police bail.
