OSLO - Norwegian mass killer Anders Behring Breivik, who refused to show remorse for killing 77 people in 2011, hugged his mother and apologised for ruining her life before she died of cancer this year, according to a new biography.
"The Mother", based on hours of conversations with Wenche Behring Breivik by journalist Marit Christensen and published on Thursday, says she once described herself as the world's "saddest mother" who both hated and loved her son.
She had no inkling that he was planning the attacks on July 22, 2011, cooking him a dinner of spaghetti that got cold as she waited in vain for his return and watched the news of bombings and shootings by an unknown killer.
She broke down in tears when the police came to her house that night to say Anders Breivik was to blame for the massacre - a bombing in Oslo that killed 8 and a shooting rampage on a nearby island that killed 69, many of them teenagers.
Breivik, a right-wing anti-Islamic fanatic now aged 34, is serving Norway's maximum sentence in jail for the attacks, which were aimed at the Labour-led government and its youth wing.
A few days before Wenche Breivik died of cancer in March, she was taken by ambulance to visit her son in jail.
Glass divided them on previous visits but this time Anders Breivik was allowed out. Still in handcuffs, he put his arms over and around his mother in a hug. "Sorry that I have ruined your life," he whispered, the book said.
