The carnage caused by Anders Breivik began with a bomb in Oslo and culminated in a massacre of young people on the island of Utoya.

A Norwegian gunman disguised as a police officer beckoned his victims closer before shooting them one by one, claiming at least 84 lives, in a horrific killing spree on an idyllic island teeming with youths that has left this peaceful Nordic nation in mourning.

The man in the police uniform shouted for the campers to come closer. When they did, he killed them.

A Norwegian who dressed as a police officer to gun down summer campers killed at least 80 people at an island retreat, police said today.
