Italy is hunting for five terror suspects after the FBI alerted the country to potential attack plots.

“Since yesterday afternoon, our security forces have been working to find five people,” Foreign Minister Paolo Gentiloni said Thursday, AFP reports.

“The minister of the interior has explained many times that we are at a very high level of alert covering symbolic sites, places where people gather, from stadiums to cathedrals, and St. Peter’s in particular, which were, among others, the places highlighted by the FBI yesterday,” he continued. “We always take such signals of alarm very seriously, especially when they come from the United States.”

The U.S. embassy in Rome also posted a security message on Wednesday urging vigilance among American visitors to Italy (the State Department has not, however issued an official travel warning for the country). The message identifies St. Peter’s Basilica in Rome and The Duomo and La Scala in Milan as potential targets.

The warnings come after Nov. 13 terror attacks in Paris left 129 people dead.
