"The ETA admitted that the history of its activities was a failure. It has gained nothing from either the murders or the end of those deeds, and it will get nothing in view of its self-dissolution. ETA crimes will be investigated and continue to be subject to prosecution. No, there will be no impunity whatsoever," Rajoy said at a press conference, as quoted by El Pais newspaper.
The prime minister recalled that as many as 853 people had fallen victim to the ETA over 50 years.
On May 2, the group announced its full dissolution and end of all activities.
