The trial for Anders Behring Breivik, the perpetrator of the 2011 Norway attacks, begins in Oslo, Norway.

The 2011 Norway attacks, referred to in Norway as 22 July (Norwegian: 22. juli) or as 22/7, were two domestic terrorist

attacks by Anders Behring Breivik against the government, the civilian population, and a Workers' Youth League (AUF) summer camp, in which 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 eight people and injured at least 209 people, twelve severely.The second attack occurred less than two hours later at a summer camp on the island of Utya in Tyrifjorden, Viken (then Buskerud). The camp was organised by the AUF, the youth division of the ruling Norwegian Labour Party (AP). Breivik, dressed in a homemade police uniform and showing false identification, took a ferry to the island and opened fire at the participants, killing 67 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 Gjrv Report concluded that Norway's police could have prevented the bombing and caught Breivik faster at Utya, 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 right-wing extremist, on Utya 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, the maximum sentence allowed in Norway.

The trial of Anders Behring Breivik, the perpetrator of the 2011 Norway attacks, took place between 16 April and 22 June 2012 in Oslo District Court. Breivik was sentenced to 21 years of preventive detention on 24 August 2012. 170 media organisations were accredited to cover the proceedings, involving some 800 individual journalists.The main question during the trial became the extent of the defendant's criminal responsibility for these attacks and thereby whether he would be sentenced to imprisonment or committed to a psychiatric hospital. Two psychiatric reports with conflicting conclusions were submitted prior to the trial, leading to questions about the soundness and future role of forensic psychiatry in Norway.
