The prosecution continues its questioning of Norwegian mass murderer Anders Behring Breivik on the fourth day of the trial in Oslo.

Arriving in court in hand cuffs , Breivik made no far-right salute, unlike previous days. His lawyers had asked him not to salute in deference to the victim families but sceptics believe it is part of his defence strategy. The prosecution will today focus on the first of his two attacks, and the circumstances, leading up to the bombing of a government building.

Yesterday said he joined a gun club in 2010 as part of his preparations which he had been planning since 2008 and that he had used computer games to rehearse scenarios before he bombed a government building in Oslo, killing eight people and injuring 209. Today he said he originally planned to carry out three car bombs but settled on just on in the end.
