Greek police say two men have been shot and are believed dead in a drive-by shooting outside an office of the far-right, Nazi-inspired Golden Dawn party in Athens.

A party statement says two men aged 20 and 23 have been shot dead and a third man was injured in the attack.

A police official says the men were shot by two men on a motorcycle in the Iraklio neighborhood late Friday. It was unclear whether the victims were Golden Dawn members. The official spoke on condition of anonymity.

No arrests have been made.

Golden Dawn's leader and two lawmakers have been jailed pending trial on charges of forming a criminal group. The party has denied any wrongdoing.
