Three the worst terrorist attacks in the beginning of the XXI century

2011, Norway attacks


It was the deadliest attack in Norway since World War II, and a survey found that on average, 1 in 4 Norwegians knew "someone affected by the attacks". The European Union, NATO and several countries around the world expressed their support for Norway and condemned the attacks. On 13 August 2012 Norway's prime minister received the Gjørv Report which concluded that Norway's police could have prevented the bombing of central Oslo, caught mass killer Anders Behring Breivik faster at Utøya and that more security and emergency measures to prevent further attacks and "mitigate adverse effects" should have been implemented on 22 July.

The Norwegian Police arrested Anders Behring Breivik, a then 32-year-old Norwegian right-wing extremist, on Utøya Island and charged him with both attacks. The trial against him took place between 16 April and 22 June 2012 in Oslo District Court, and as at all his remand hearings Breivik admitted to having carried out the actions he was accused of, but denied criminal guilt and claimed the defense of necessity. On 24 August 2012 Breivik was convicted as charged and sentenced to 21 years of preventive detention in prison, which at the end can be repeatedly extended for 5 years as long as he is considered a threat to society.
