Norway commemorated the 15th anniversary of the 22 July 2011 attacks on Tuesday, marking the day far-right extremist Anders Behring Breivik killed 77 people — eight in a car bomb targeting Oslo's government quarter and 69, mostly teenagers, in a shooting rampage at a Labour Party youth camp on the island of Utøya. A new memorial artwork was unveiled in central Oslo, and survivors' organisations warned that the threat of hate and far-right radicalism has grown rather than receded, partly driven by social media. Gaute Skjervø, a Utøya survivor who now leads the Labour youth wing, said he continues to receive threats from people who express regret that the attacker did not finish the job — underscoring warnings from multiple voices that the ideological environment that produced the massacre remains a live danger.
