Norway’s worst massacre since World War II saw a lone man killing 76 people end July. The gunman, believed to be a right-winger, indiscriminately opened fire at the Utoeya island youth camp in Norway, hours after a bombing in the capital Oslo killed seven people.

Police have charged Anders Behring Breivik, a Norwegian dressed as a police officer, for both the incidents. He is said to have acted alone, though he e-mailed his manifesto to 1,003 e-mail addresses, about 90 minutes before he detonated a bomb in Oslo.

The Norwegian admitted to carrying out both the incidents told a court that two cells of collaborators were in his “Knights Templar” group that aimed to ‘save’ Europe from Muslims. The Police attorney Christian Hatlo said nothing could be ruled out on accomplices.
