On July 22, 2011, the island of Utøya, 40 kilometers from Oslo, became the site of the deadliest crime in Norway's history since World War II. The far-right terrorist Anders Breivik detonated a bomb near the government building in Oslo, killing eight people. Afterward, disguised as a police officer, he reached the island and for an hour and a half shot participants of the summer camp of the Workers' Youth League (AUF) — the youth wing of the Norwegian Labour Party. 69 people were killed on the island, most of them teenagers and very young activists.
