Rome's public transport and tourist sites to get extra security.
Rome will have more than 2,000 extra police officers on duty from 23 November, 15 days before the Vatican's Holy Jubilee of Mercy begins on 8 December.
The new measures were announced by Rome police chief Nicolò D'Angelo as part of heightened security measures following the 13 November attacks in Paris, in which terrorists killed 129 people.
Rome will increase security on the public transport network, at the Stadio Olimpico football stadium and in the city suburbs. Security will also be increased at major Holy Jubilee events, which runs until 20 November 2016. Metal detector security gates will be installed at the Colosseum and Italian and Vatican police are working together to double security at St Peter's. At present 140 tourist sites are under surveillance.
Italian premier Matteo Renzi has urged people not to be "overwhelmed by hysteria and fear" as the capital's metro system continues to experience false bomb scares. He also said that those who spread false alarms could face prosecution.
The city's annual Musei in Musica initiative attracted only 25,000 visitors, down from 70,000 last year.
However it was business as usual at the Vatican's Sunday Angelus ceremony on 22 November when more than 30,000 faithful showed up to receive a blessing from Pope Francis.
