Italian police have been checking all embassies in Rome after bombs went off at two missions, in what the mayor is calling a ''wave of terrorism''. Parcel bombs were sent to the Swiss and Chilean embassies. Two employees working in the mailroom were injured when the devices went off in their hands. It comes seven weeks after a series of parcel bombs were sent to embassies in Athens and foreign governments around Europe. Earlier this week, a device was discovered in an underground train in Rome - but it had no detonator or explosives. Police are so far not linking the parcel bombs to the train device. Italy's Interior Minister had said ''anarchists'' may be to blame for the embassy explosions. And there are now reports an Italian anarchist group left a claim of responsibility at the scene of one of the attacks. From Rome, Sabina Castelfranco reports.
