Anders Behring Breivik 'planned to bomb Barack Obama at Nobel Peace Prize ceremony' The plot is similar to the bombing of government buildings Breivik carried out last July, hours before he drove to a youth camp on the island of Utoya to commit what Norwegian prosecutors have described as Norway's worst atrocity of modern times. Breivik has admitted to carrying out the attacks on July 22, which left 77 people dead, but claims they were "necessary" to alert the Norwegian people to what he believes is a creeping Islamic takeover. The trial is set to begin on April 16, almost nine months after he carried out the attacks. Prosecutors said last that month they would proceed on the assumption that Breivik is insane, following the recommendations of the official forensic psychiatric report, and argue that he be forcibly committed to a mental institution. But this may change if a second psychiatric report, commissioned by the court in January on the request of families of his victims, and expected to be made public on April 10, concludes that Breivik should be held responsible.
