MILAN (AP) — U.S. Immigration and Customs Enforcement agents will have a security role during the upcoming Milan Cortina Winter Games, according to sources at the U.S. embassy in Rome.

The sources who confirmed ICE participation on Tuesday said that federal ICE agents would support diplomatic security details and not run any immigration enforcement operations.

During previous Olympics, several federal agencies have supported security for U.S. diplomats, including the investigative component of ICE called Homeland Security Investigations, the sources said. They could not be named because they are not authorized to speak publicly.

Milan Mayor Giuseppe Sala said that ICE would not be welcome in his city, which is hosting most ice sports.

“They are not welcome in Milan. They are not aligned with our democratic way of managing security,″ Sala told RTL Radio 102.
