Just days after letter bombs sent to the Swiss and Chilean embassies detonated, injuring two people,

disposal experts defused a similar device mailed to the Italian capital's Greek embassy. The Informal

Anarchist Federation has claimed responsibility for all the explosives. Suspicious packages received

recently at other embassies proved to be false alarms. Authorities are investigating potential links

between anarchist groups in Italy and Greece, where similar bombings took place in November.
