The hearing took place amid a massive security operation that aimed to avoid escape attempts by Mr. Breivik and protect him against potential avengers.
Mr. Breivik walked roughly the same route as the one he took during the shooting spree and explained what happened with as little interference as possible from police, Mr. Hjort Kraby said.
The entire hearing was filmed by police and may later be used in court, he added.
Police disperse opposition protest
MOSCOW — Russian police quickly broke up a protest of a few dozen opposition activists and detained about 30 participants on Friday.
The action, dubbed the “Day of Wrath,” was organized by the Left Front, whose leader Sergei Udaltsov is serving a 15-day jail sentence for taking part in an unsanctioned rally on July 31.
A few dozen protesters gathered Friday outside a subway station near the Kremlin, chanting “Free Sergei Udaltsov!” and some of them lay down on the ground. Police dispersed the demonstrators within minutes.
Amnesty International has declared Mr. Udaltsov a prisoner of conscience and demanded his immediate release.
Russia’s beleaguered opposition has made regular attempts to hold protests, but authorities have banned their rallies and police move quickly to break them up.
