The pope cited the killing of a naval officer's wife, saying that immigrants need the means for "an honest and dignified life," the news agency Ansa reported. She was allegedly robbed and killed by a Romanian immigrant living in a shantytown.

''A tragic event like the killing of Giovanna Reggiani suddenly brought the city's residents face to face with not only the problem of security but also the serious urban decay in certain areas of Rome,'' he said.

He said there is an "education emergency" and said young people are not given a firm moral grounding.

Benedict had lived in Rome for more than 20 years when he became pope. A cardinal serves as vicar for most of his duties as bishop.

Rome Mayor Walter Veltroni and Lazio regional President Piero Marazzo did not comment on the pope's remarks after the meeting. Some conservative politicians and publications seized on them.

''More than a condemnation, it sounds like an excommunication for Veltroni,'' Northern League Sen. Roberto Calderoli said.
