Several cars, including that of a Finnish diplomat, and the offices of a political party were damaged by gas canister attacks in Athens on Tuesday. No one was hurt. A home-made gas canister bomb exploded under the diplomat's car, setting it on fire and burning five more cars nearby. A second attack damaged the offices of the ruling conservative New Democracy party in the Athens district of Polygono. Police said a so far unknown group named Anti-state Justice claimed responsibility with a call to a local TV station.
