Unknown Group Says It Killed 2 Activists in Greece Greek police are investigating a statement by an unknown group claiming responsibility for the killing of two members of the far-right Golden Dawn party. The group, Fighting Popular Revolutionary Forces, said the Nov. 1 killings were retribution for the slaying of a left-wing activist rapper by a Golden Dawn member in September. The group threatened to keep killing Golden Dawn members and their supporters. The Zougla (Jungle) news website said it reported the statement Saturday after receiving an anonymous phone call saying it could be found on a USB stick in a plastic bag at an Athens location. A member of the police counterterrorism division said it is studying the statement which wasn't from any known terrorist group. The official spoke on condition of anonymity because he was not authorized to speak to the media.
