2011 Norway attacks

On 22 July 2011, far-right extremist Anders Behring Breivik committed two domestic terrorist attacks in Norway against the government, the civilian population, and a Workers' Youth League (AUF) summer camp, in which a total of 77 people were killed.

The first attack was a car bomb explosion in Oslo within Regjeringskvartalet, the executive government quarter of Norway, at 15:25:22 (CEST). The bomb was placed inside a van next to the tower block housing the office of the then prime minister Jens Stoltenberg. The explosion killed 8 people and injured at least 209 people, 12 severely.

The second attack occurred less than two hours later at a summer camp on the island of Utøya in Tyrifjorden, Buskerud. The camp was organised by the AUF, the youth wing of the ruling Norwegian Labour Party (AP). Breivik, dressed in a homemade police uniform and showing false identification, arrived at the island claiming to be performing a routine check following the bombing. His presence raised the suspicions of the camp's organizer and subsequently a security guard, prompting Breivik to kill them both. He then opened fire at the participants, killing 69 and injuring 32. Among the dead were friends of Stoltenberg, and the stepbrother of Norway's crown princess Mette-Marit.

The attack was the deadliest in Norway since World War II. A survey found that one in four Norwegians knew someone affected. The European Union, NATO and several countries expressed their support for Norway and condemned the attacks. The 2012 Gjørv Report concluded that Norway's police could have prevented the bombing and caught Breivik faster at Utøya, and that measures to prevent further attacks and "mitigate adverse effects" should have been implemented.

The Norwegian Police arrested Breivik, a 32-year-old Norwegian far-right extremist, on Utøya island and charged him with both attacks. His trial took place between 16 April and 22 June 2012 in Oslo District Court, where Breivik admitted carrying out the attacks, but denied criminal guilt and claimed the defence of necessity (jus necessitatis). On 24 August, Breivik was convicted as charged and sentenced to 21 years of preventive detention in prison with the possibility of indefinite five-year extensions for public safety, the maximum sentence allowed in Norway.
