Norway's chief of police has quit following a report which found that police could have prevented all or part of the attacks carried out by Anders Breivik.

Norwegian security services could have prevented all or part of an attack by far-right militant Anders Breivik, who killed 77 people in a bombing and gun massacre last year, a government commission said yesterday.

Survivors of the Norway youth camp massacre relived their terrified attempts to escape as they gave evidence at the Anders Breivik trial today.
