Anders Behring Breivik, also known as Fjotolf Hansen, gained notoriety for committing the 2011 Norway attacks, which included a bombing in Oslo and a mass shooting at a youth camp on the island of Utøya. These attacks resulted in the deaths of 77 people and left many others injured. Breivik's actions were motivated by his extreme right-wing ideology and anti-Muslim sentiments.
Born on February 13, 1979, in Oslo, Norway, Breivik grew up in a middle-class family and later became involved in far-right politics. He authored a manifesto outlining his anti-immigrant and anti-Islamic views, which he claimed were the basis for his attacks. Breivik was convicted of mass murder and terrorism in 2012 and is currently serving a 21-year prison sentence, which can be extended indefinitely as long as he is deemed a threat to society. His case continues to be a subject of public interest and debate regarding extremism and terrorism.
