As Norway struggles to come to terms with its greatest loss of life in decades, all eyes are on the man charged in the explosion in central Oslo and the deadly shooting rampage at a youth camp.
While police have not officially named him, Norwegian television and newspaper reports have identified the suspect as 32-year-old Anders Behring Breivik, of Norwegian origin.
A picture is emerging, gleaned from official sources and social media, of a right-wing Christian fundamentalist who may have had an issue with Norway's multi-cultural society.
Norwegian and international news outlets have run photographs of a blond man with blue-green eyes and chiseled features, dressed in a preppy style.
A victim who was shot during the attack at the youth camp on Utoya island told CNN Saturday that he had seen pictures of Breivik taken from what is believed to be his Facebook page and shown on NRK and TV2. The victim said he recognized the man from the news reports as the gunman.
Breivik is a member of the Oslo Pistol Club and has three weapons registered in his name, according to leading Norwegian newspaper VG, citing Norway's official weapons register. They are a Glock pistol, a rifle and a shotgun, VG reported.
NRK reports that Breivik does not have a military background and was exempt from Norway's mandatory military service. He has not had any special military training, it adds on its website.
He was a youth and adult member of the conservative Fremskrittspartiet (FrP) or Progress Party, VG newspaper reports, remaining involved until 2007. The party's most prominent manifesto pledge is to minimize immigration.
His membership was confirmed by a senior party member, Jonas Kallmyr, who is quoted by VG as saying that encountering Breivik was "like meeting Hitler before World War II."
The leader of the Progress Party, Siv Jensen, told Norwegian broadcaster TV2 News she was "horrified" to learn that the suspect was a former member of her party.
"But this is first and foremost an attack against the entire nation. It has affected all of us," she said, saying that her party members stood in solidarity with the youth movement of the Labour Party.
A post in Breivik's name on an online forum, Document.no, from December 2009, talks about non-Muslim teenagers being "in an especially precarious situation with regards to being harassed by Islamic youth."
