Authorities are investigating after a device exploded outside of a carabinieri barracks on the outskirts of Bologna, hours before Prime Minister Matteo Renzi was due to visit the city.

Renzi is campaigning a week before Italians vote on a referendum on constitutional reform, but it’s not clear if the blast is linked to the issue.
