Italian Prime Minister Silvio Berlusconi has said in an interview that he had "precise" information before Christmas about a threat of a Christmas Day attack on Rome and the Vatican.
He said in the interview with the Libero newspaper, conducted on Christmas Eve, he had received "precise and verified news of an attack on Rome on Christmas Day. A hijacked plane above the Vatican... An attack from the sky."
"The threat from terrorism is extremely high at this moment. I've spent today (Dec 24) in Rome to deal with the situation," Berlusconi added in the interview published today.
"Now I'm calm. It will pass... I don't say this out of fatalism but because I am aware that our defences are very high. If that is what they have organised, they won't make it."
He gave no details of who was believed to be behind the planned attack or of any measures taken to prevent it.
No one was immediately available for comment at the prime minister's office or the interior ministry, which is in charge of national security.
At the Vatican, chief spokesman Joaquin Navarrro-Valls told Reuters: "As is customary, we do not comment on matters security".
