ATHENS, Greece - Greek authorities have charged two local men with terrorist acts in connection with a wave of mail bombs that targeted diplomatic missions in Athens.

Court officials say the suspects, whose names have not been released, were charged Tuesday with belonging to a terrorist group, acts of terrorism and causing explosions that endangered human lives. The men, both in their twenties, were arrested Monday.

The charges carry a minimum 25-year prison sentence.

The charge sheet did not specify what group the two men allegedly belonged to. Police say the one suspect was already wanted for alleged membership in a small radical anarchist group named Conspiracy Nuclei of Fire.

On Tuesday, small mail bombs exploded outside the Russian and Swiss embassies in Athens and another three were destroyed by police.
