OSLO, Norway (AP) — Norwegian police have set off a replica of the car bomb that ripped through Oslo's government district in July, killing eight people.
A police spokesman says investigators built the 2,100 pound device using fertilizer found at the bomber's farm and detonated it at a military firing range. They say they were trying to measure the impact of the explosion.
Anders Breivik confessed to carrying out the bombing and a mass shooting at a Labor Party youth camp on an island outside of Oslo, which left another 69 people dead.
Breivik has been helping police reconstruct how he carried out the attacks. However, he has pleaded not guilty to terrorism charges, claiming he is in a state of war to protect Europe from being taken over by Muslim immigrants.
Members of a commission investigating how authorities responded to the incidents toured the government offices where the bomb went off. The block has been sealed off since the blast and debris is still being cleared from the area.
