Here is a timeline of some major attacks in Greece over the
last two years:

Jan. 2007 - Guerrillas fire a grenade at the U.S. embassy in
Athens, hitting its facade.

April 2007 - Gunmen attack the Nea Ionia police station in

Ministry in Athens. They said it was in revenge for the death of
15-year-old Alexandros Grigoropoulos.

causing a fire which seriously damages the Piraeus Bank branch
in the northern Athens suburb of New Psychico.
