The families of some 20 Utøya massacre victims are planning to take court action against either the state or the police.

The goal of the action is to establish responsibility for the inadequate police response to the events of July 22, 2011, when Anders Brevik killed 69 people on the island of Utøya where the Norwegian Labour Party had organised a youth camp.

Most of the families are relatives of people who were shot during the last 21 minutes of the massacre, at a time when, they allege, security forces should have already intervened.
