The 2011 Norway attacks, also known as 22 July, were two far-right extremist terrorist attacks carried out by Anders Behring Breivik. The first attack occurred when Breivik detonated a car bomb in Oslo’s government quarter, killing eight people and injuring over 200. Less than two hours later, Breivik, dressed as a police officer, attacked a Workers' Youth League (AUF) summer camp on the island of Utøya, killing 69 people, mostly teenagers, and injuring 32.
These attacks were the deadliest in Norway since World War II. Breivik was arrested on Utøya, admitted to the attacks, but claimed they were necessary. He was tried and convicted in 2012, receiving a 21-year sentence with the possibility of indefinite extensions. A government report later found that Norwegian police could have responded more effectively to prevent some of the deaths. The attacks deeply impacted Norway, with one in four citizens knowing someone affected. The international community condemned the violence and expressed support for Norway.
