His trial awaits prosecutors' stance on sanity
The BBC's Richard Galpin says judges will decide whether Breivik will go to prison or a secure psychiatric ward
The trial of Anders Behring Breivik in Oslo is waiting to hear whether prosecutors will ask for him to be sent to prison or into psychiatric care.
They have begun summing up their case, with their decision resting on whether they believe he was sane when he killed 77 people in Norway last year.
Conflicting psychiatric evaluations were presented earlier.
Breivik bombed government buildings in Oslo before shooting young Labour Party supporters at an island camp.
As well as killing 77 people, he injured 242.
Breivik sought to justify his attacks by saying they were necessary to stop the "Islamisation" of Norway.
The defence concludes on Friday, and a verdict is expected in July or August.
