2011 Norway attacks
two sequential lone wolf terrorist attacks in Norway on 22 July 2011

On 22 July 2011, 32-year-old far-right extremist Anders Behring Breivik committed two domestic terrorist attacks in Norway against the government, the civilian population, and a Workers' Youth League (AUF) summer camp, in which a total of 77 people were killed.
The first attack was a car bomb explosion in Oslo within Regjeringskvartalet, the executive government quarter of Norway, at 15:25:22 (CEST). The bomb was placed inside a Volkswagen Crafter van next to the tower block housing the office of the then prime minister Jens Stoltenberg. The explosion killed 8 people and injured at least 210 people, 12 severely.
The second attack occurred less than two hours later at a summer camp on the island of Utøya in Tyrifjorden, Buskerud. The camp was organised by the AUF, the youth wing of the ruling Norwegian Labour Party (Ap). Breivik, dressed in a homemade police uniform and showing false identification, arrived at the island claiming to be performing a routine check following the bombing. His presence raised the suspicions of the camp's organizer and subsequently a security guard, prompting Breivik to kill them both. He then opened fire at the participants, killing 69 and injuring 33. Among the dead were friends of Stoltenberg, and the stepbrother of Norway's Queen Mette-Marit.

Why this record matters
The subject matters to the general reference register because the source frames it as two sequential lone wolf terrorist attacks in Norway on 22 July 2011. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 26, 2026. The linked authority identifier is Q79967. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2011.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
