Images are shown that Breivik took of his barn and of the manufacturing area where the bomb was made. One image shows four food blenders, another shows a cement mixer, used for crushing and mixing ingredients of the bomb. 10.32am: Pictures are shown of Breivik's farm, described by the prosecutor as "a good place to manufacture the bomb." The bomb was manufactured as Breivik described to the police, the court hears. Police made a bomb, according to the instructions given to Breivik, and tested it. The court is shown an image of the bomb created by the police. A drawing of the bomb made by Breivik for the police shows the location of the primary explosives, the secondary explosives and the booster. 10.27am: Moving onto what the prosecutor calls "equipment," the prosecutor says Breivik bought 43 weapon-related items. Four of these were bought from abroad. 10.24am: Breivik again smiles as a picture is shown of him in uniform (left). The prosecutor moves onto equipment. Another picture is shown of Breivik holding a weapon, taken from his manifesto (see below). A badge photoshopped onto the uniform, shown in close up, says "Marxist hunter England." On the uniform, it had been changed to say "Marxist hunter Norway." It also said "Multicultur [sic] traitor hunting permit." Breivik bought 36 items from 8 countries to make his uniforms, the court hears 10.17am: The prosecution moves on to the three-part compendium created by Breivik - the manifesto for his actions. 10.13am: The prosecutor is talking about Breivok's playing of World of Warcraft. He is said to have played the game "full-time" between the summer of 2006 and summer 2007. The prosecutor describes it as a violent game. As a picture is shown of one of the characters Breivik adopted in the game, the accused smiles. The court also saw a picture of the bedroom where he played the game. 10.04am: The prosecutor said that the Knights Templar anti-Islam network that Breivik claimed to have joined "does not exist" as he describes it. The prosecutor proceeds with a "timeline" of Breivik's life, starting with his birth in 1979, running briefly through his schooling and going on to three companies he set up. "Several important incidents" take place in Breivik's life in 2003, including making "significant" money selling fake degree and diploma certificates, dropping out of the job he had for six years and going to live on an appartment on his own, says the prosecutor. 9.57am: The court has resumed after a short break. Before the prosecutor began, the judge warned that there would be "very strong images" of the events of 22 July 2011. The judge said these images would not be broadcast on television (the trial is being televised) and so said the prosecutor should give plenty of notice before the video is to be screened 9.53am: The names of the 77 people and the details of how they were killed were read out in court this morning. My colleague, Helen Pidd, who in the courtroom, is tweeting from the trial and provided an example from the indictment. 9.40am: Good morning. Welcome to live coverage of the first day of the trial of Anders Behring Breivik, who has admitted killing 77 people in a bomb-and-shooting massacre in Oslo, Norway, last summer. Breivik has rejected the authority of the court at the opening of the trial. Dressed in a dark suit, he smiled as a guard removed his handcuffs in the crowded courtroom. His first words were: I don't recognize Norwegian courts because you get your mandate from the Norwegian political parties who support multiculturalism. Breivik also said he doesn't recognize the authority of Judge Wenche Elisabeth Arntzen, because he said she is friends with the sister of former Norwegian prime minister and Labour party leader Gro Harlem Brundtland. He has pleaded not guilty, telling the court: I acknowledge the acts but I do not plead guilty and I claim that I was doing it in self defence. He faces a maximum sentence of 21 years in prison but could be held indefinitely if he is considered a continuing danger.
