OSLO: The Norwegian anti-Muslim extremist, Anders Behring Breivik, comprehensively elaborated the massacre on Friday and shocked the entire Norwegian nation. Breivik was seen calm and cold when he described how he chased teenagers room by room and shot them dead on an island summer camp last year in Norway.

Standing in the court, Breivik stated that he shot majority of his victims several times in order to ensure their death. He stated that he took the first shot at his victims to bring them down and then finished them with a shot to their head.

His trial, now into its fifth day and due to last in 10 weeks, has shocked a calm and peaceful region of Norway. The massacre is considered to be the most violent act since World War 2.

He further described how his body tensed up when he carried out the carnage at the ruling Labour Party's youth camp on Utoeya island. "I took the gun out and thought it was now or never, and it seemed like a year," he said.

Later, he calmly elaborated how he continued with his rampage, shooting 69 people with majority of them being teenagers.

"When I make a follow up shot, his (victim's) cranium bursts and there are brains flowing out. I remember that very well," Breivik said. He further stated that his victims got paralyzed before he killed them. "I walk towards a group of 10 who have stopped. They have stopped running and just lie down. I go to them and shoot them all to the head. They were paralyzed most likely."

Breivik, 33, admits the killings but has pleaded not guilty. He says he was defending his country against Muslim immigrants by setting off a car bomb that killed eight people at government headquarters in Oslo before travelling to the island to carry out the massacre.

"It was extremely hard to shoot that first shot, it is contrary to human nature. But after that... it became easier," he said. "To take a human life is the most extreme you can do, but you weigh that against superior motives."

Breivik arrived at the island, dressed as a Police Officer. He shot some of his victims while they were swimming, trying to escape to the mainland. "Calmly I raised my rifle... and shot from a distance toward these people. I know that I hit at least four of them."

"I shouted on two occasions, you are going to die today, Marxists... and people panicked completely," Breivik told the silent courtroom. "The object was to kill everyone on the island by scaring them into the water."

In one room alone, he said: "I shoot perhaps four or five persons. I think I shoot them once in the head first, until I have shot them all, and then I fire follow-up shots afterwards."

He reloaded. One person tried to attack him but was shot.

"Many people scream and beg for their lives. I don't really remember what they were saying."

Police have reported that there were 564 people present on the island at that time and Breivik told the court that he had planned to kill all of them, including former Norwegian Prime Minister Gro Harlem Brundtland who was there that day.

On Thursday, Breivik had stated that he had planned to behead her and upload that film onto the internet, but the former President had left the island several hours before Breivik’s arrival.

Breivik also added that he had started his training five years prior to the attacks in order to suppress his feelings, after he decided to use violence to alert Europeans to what he considered the loss of their culture.

For his training, he played video games up to 16 hours in a day and practiced daily meditation to "hammer away" at emotions and embrace his own death, he said.

"One might say that I was quite normal until 2006 when I started training, when I commenced de-emotionalizing," he told the court. "And many people will describe me as a nice person or a sympathetic, caring person to friends and anyone."

"I've had a dehumanization strategy towards those I considered valid targets so I could come to the point of killing them. ... It is easy to press a button and detonate a bomb. It is very, very difficult to carry out something as barbaric as a firearms operation."

Defense attorney Geir Lippestad stated that Breivik's only goal at the trial was to prove himself sane.

"He thinks he has explained his views satisfactorily, the way he wishes, and he thinks that people understand what he is saying, at least the group he talks to," Lippestad stated. (Reuters)
