7 years ago today the terrorist attacks by Anders Behring Breivik took the lives of 77 people in the government quarter in Oslo and at Labor Party summer camp in Utøya. Most of the victims were the teenagers at the camp.

It was the deadliest attack in Norway since World War II, and a survey found that one in four Norwegians knew “someone affected by the attacks”.

The terrorist Anders Behring Breivik, a 32-year-old Norwegian right-wing extremist,is still serving his 21 years prison sentence (the maximum sentence allowed in Norway).
