Terrorist attacks (?) in Oslo,Norway

In such a peaceful country, we couldn't expect such cruel terrorist attacks would happen. In Oslo, Norway, the government office was attacked by a car bomb and several people were killed. About 90 minutes later, in a camp site on a small island named "Utoya" 30 kms off Oslo, a gunman shot randomly at young people who were taking part in the rally organized by Norway's governing party Labor Party, and killed at least 85 people.
