Italian Carabinieri stand in front of the Greek embassy in Rome on December 27, 2010 after an explosive package was found. Some other suspect packages at other embassies in the city have proved to be false alarms. Last week, an Italian anarchist group claimed responsibility for parcel bombs that wounded two people at the Swiss and Chilean embassies in Rome.
