Anders Behring Breivik is a Norwegian domestic terrorist responsible for the 2011 attacks in Oslo and on the island of Utøya, the deadliest act of violence in Norway since World War II. His coordinated attack involved a car bombing followed by a mass shooting, resulting in 77 deaths. Breivik was arrested on the day of the attacks and later convicted of terrorism and mass murder. He received the maximum sentence under Norwegian law, with provisions allowing for indefinite extension based on continued risk.

Early Life
Anders Behring Breivik was born on February 13, 1979, in Oslo, Norway. His early life was shaped by family instability following his parents’ separation, and he was raised primarily by his mother. Reports from his youth describe a socially withdrawn individual who struggled with identity and interpersonal relationships.
As he entered adulthood, Breivik became increasingly isolated and disengaged from mainstream society. He developed strong ideological beliefs centred around nationalism, anti-immigration sentiment, and opposition to multiculturalism. Over time, these views intensified, forming the foundation of his worldview and later actions.
Killing Spree
The attacks took place on July 22, 2011, and are classified as a coordinated mass-casualty terrorist event rather than a spree or serial pattern.
Breivik first detonated a vehicle-borne explosive device in Oslo’s government district, causing significant destruction and loss of life. He then travelled to the island of Utøya, where a youth political camp was underway, and carried out a sustained shooting attack. The two-stage operation resulted in a combined death toll of 77 victims within a single day.
Modus Operandi
Breivik’s actions were highly planned and executed with clear intent. The attack combined the use of an improvised explosive device with a firearms assault, demonstrating preparation across multiple methods.
He used deception to gain access to Utøya, presenting himself as a police officer before initiating the shooting. The operation reflected logistical planning, acquisition of materials, and premeditated targeting linked to ideological motivations. The scale and coordination distinguish the event as an act of domestic terrorism rather than impulsive violence.
Capture
Anders Breivik was apprehended on July 22, 2011, on the island of Utøya shortly after the shooting concluded. He surrendered to police without resistance.
The immediate capture ensured that he faced trial and provided authorities with direct access to the perpetrator, unlike many comparable large-scale attacks.
Trial & Sentence
Breivik’s trial took place in 2012 and focused heavily on the question of criminal responsibility and mental state. Multiple psychiatric evaluations were conducted before the court ultimately determined that he was legally sane and fully accountable for his actions.
He was convicted of terrorism and mass murder and sentenced to 21 years of preventive detention, the maximum penalty under Norwegian law. This sentence includes provisions for indefinite extension in five-year increments if he is deemed an ongoing threat to society. Terrorism and mass murder: 21 years preventive detention (extendable indefinitely)
