Italy's interior minister says almost $110 million has been spent on security for the Turin Winter Olympics, and that amount is expected to grow in the next few weeks.

Interior Minister Giuseppe Pisanu gave the first official figures for security spending Monday, and said security arrangements are on schedule. Pisanu said Italian officials are "reasonably optimistic" they will be able to foil any terrorist threats, although there have been no specific threats against the Olympics or Italy.

More than 9,000 extra officers will help protect the Games, while a center coordinating the intelligence from national and international security forces will provide surveillance.

Pisanu said that Italian security will be in charge during the Olympics, though foreign security agencies will be included in the information center. The Italians are drawing on their experience handling previous major events, including the funeral of Pope John Paul II at the Vatican.
