Police investing the slaying of two members of the far-right Golden Dawn party and the wounding of a third say the gun used in the Friday evening attack had not been used in previous terrorist attacks.

The assailant fired 12 rounds from a Zastava Tokarev type semi-auto pistol, police say.

A police source, speaking on condition of anonymity because officers were not authorized to comment on the ongoing investigation, said Saturday that a video from a nearby security camera confirmed accounts from Golden Dawn lawmakers that the assailant started firing from 15 meters (yards) away and finished off his victims from point-blank range. The gunman fired at a fourth Golden Dawn member, who managed to enter a building unharmed.
