A bomb in a package addressed to the Dutch Embassy was seized at another Athens delivery company.

Greek authorities said one of the men is suspected of belonging to Conspiracy Nuclei of Fire, a domestic anarchist group that has carried out dozens of arson and crude bomb attacks — part of a wave of violence that broke out following massive riots triggered by the police shooting of a teenager in December, 2008.

The incident began when a bomb went off in the hands of a delivery-service employee, leaving her with injuries that hospital officials said were not life-threatening.

Police spotted two suspicious-looking men at a bus stop a few hundred meters away and took them into custody. The men were armed and had a bomb addressed to Sarkozy and another to the Belgian Embassy in Athens.
