With hundreds of thousands of mourners and 130 official delegations expected, the security measures for the late pontiff's funeral are among the most extensive ever arrayed in Rome.

Thousands of police officers will be deployed for the funeral, with reinforcements arriving from several Italian regions. That’s before considering the security services being brought along by the 130 foreign delegations.

The area around the Holy See and along the route of the funeral procession will be protected by a full-fledged security presence covering threats from air, land and sea: a Navy destroyer near the capital, Eurofighter jets from the Italian Air Force, radar installations and anti-drone bazookas.
